Gatohaus: Outgoing Secretary's last notes

[[Category:Meeting Minutes]] {{TOCright}}

== Time and Location ==
:May 13, 2014
:Called to order at 2013 by Dan B.
:Members present: Dan, Mirage, Ben, Kevin, Katie, George, Travis, David, Phil, ITG, juri, Shawn
:Others present: Rob, Bobbie, 2 others.

:[[Quorum]]? need 14.
:: Quorum met? Called Lee for quorum on one proposal.

== Approval of Previous Meeting's Minutes ==
[[Regular Member Meeting 2014 04 08]]
(not voted on)

== Recognition ==
Dan: Thanks to all for the help at USAEF.
Reminds all that if you want to represent Hac at such events, you don't need approval.. just commitment.
Thanks to those are pursuing the free legal help that has been offered.

Ben: Travis, mirage and all that have helped with getting the spiffy new 3DPs!

== Director Reports ==
=== President's Report ===
Wants to know what we need to change in order to have enough members at the monthly meets in order to reach quorum. Please provide feedback as to whether on not we need to change the meeting time or other ideas.

=== Vice President's Report ===
n/a

=== Treasurer's Report ===
Here is the financial summary spreadsheet for April 2014: [[File:HacDC Financials 2014 04.pdf]]. We gained 3 members in the past month: Harry Detwiler, Travis Brown, and Robin Bell. We lost one member, William Gibb. We have 48 dues-paying members in good standing, 9 dues-waived members, and 3 members who are behind on dues. We have filed IRS Form 990-N (Return of Organization Exempt From Income Tax for small organizations whose annual gross receipts are normally $50,000 or less).

==== Project Awesome ====
Here is the Project Awesome spreadsheet for April: [[File:HacDC PA Projects-2014 04.pdf]]. Between less income from dues/donations and higher expenses from the truck rental for the SEM, there was no surplus this month and thus no Project Awesome dividend. :(

=== Secretary's Report ===
My pleas to the gods to slow the Earth's rotation by a few hours a day have, sadly gone unanswered.
Unfortunately, this means I'm resigning my position as Secretary.

I'll still be around, but have become too neglectful of things secretarial to continue holding the position in good conscience.

=== Director-at-Large Reports ===
==== Ben ====
nada

==== Zach ====
Nothing to report at the moment, I was traveling a lot this past month. El Presidente and I looked over the donated 60" TV LED issues last night, and Dan is going to see if he can rustle up a replacement for the ONE DEAD LED that is keeping the screen from working.

== [[:Category:Project_Awesome|Project Awesome]] Reports ==
=== Project LASER ===
Dan cleaned the laser from the Splat run. It was quite nasty.
We're considering buying a more powerful laser as the current laser is at the edge of the kind of utility we want.
Looking at replacing guides with rails to increase accuracy and lifespan.

=== Project BYZANTIUM ===

=== Project KITBUILD ===
In preparation for the 2014 Summer School session, Project KITBUILD foresees a related kit build for rookies in late June or mid-July. Because Summer School participants are required to buy their own supplies, none, or little, of Project KITBUILD's funds would be used unless soldering irons need mending or more power strips are needed.

It would be fun to have a more advanced kit build before or around that time. More on this under New Business.

=== Project SUPPLIES ===
Last month's expenses included:
* ~$100 for 2kG 3mm PLA filament.
* ~$5 for batteries.

Next month's expenses are expected to include:
* New end mill bits to replace broken drill bits for PCB pre-milling/drilling.
* 3D printer supplies/parts.
* SEM supplies/parts.
* Possibly parts for the optical table if not funded otherwise.

=== Project EXPANSION ===
Have not ordered bandsaw yet, been busy with USASEF.

=== Project SPACECAM ===
Kevin: going to leave projector cart with instructions near arcade machine. We need to to work towards cleaning the meeting room, getting rid of some of the older furniture. For the upcoming summer classes we need better infrastructure (bandwidth) and the space should be more functional.

Dan & Ben: we should get rid of the arcade machine.. Ben will try to get in touch with owner, whoever that may be.

== Member Reports ==
=== Dan B ===
Wants to start working on rewiring (power and ethernet) of the meeting room. Could use help. Will re-post request for help on list-serv.
Kevin can help on Sundays.

=== mirage335 ===
==== USASEF ====
USASEF was absolutely awesome. We had several demos, including Dan Barlow's plotter, a logic analyzer, some amateur radio equipment, possibly a working byzantium node, Dan Barlow's HeNe laser projector, and my own working [[:Category:BiosignalAmplifier]]. Our table was by far the best staffed and best equipped of any local hackerspaces.

Travis picked up a free Cube printer from 3DSystems. Hopefully, this 'appliance' 3D printer will help guarantee we have an operational printer at all times.

After making contact in person, and proceeding with some follow-up, SeeMeCNC shipped us a free Rostock Max kit, the absolute best-value printer on the market. Julia Longtin is taking care of assembly for that printer, as well as Shawn Wilson's own Rostock Max.

Given we now have two 3D printers, including one of the proposed types, I consider the budget approved (officially unconditionally, unofficially conditionally) at last month cancelled, with no plans to spend it.

==== Photolithography PCB Fab ====
Modified an EEPROM timed UV exposure box, laser cut new PCB exposure jig, and improved software toolchain. Have now fabricated full-scale high-resolution PCBs suitable for complex circuits.

Practice is required to evenly develop/etch the PCBs. Follow the tips at [[:Category:Photolithography_PCB_Fab]] .

=== Parts Library ===
Generic high-quality parts library under construction in mini-drawers. Emphasis is on the ability to rapidly prototype high-performance 2.7-3.3V analog and digital circuits.

==== Unnecessary Mess ====
Two members lost valuable cleanup time straitening out work surfaces. That time could otherwise have been used to free up more space instead. Apparently, making it absolutely clear this behavior is highly unhelpful has been insufficient. Wish we had RFID logs to personally draw attention to the individual responsible.

To be clear, this does not refer to the legitimate mess created during 3D printer commissioning, which was easily and neatly packed up this morning.

== Old Business ==

== New Business ==
Proposal on having Ben become the Secretary and Travis becoming Director at Large (taking Ben's place).
Passed (Thanks Lee!) by member vote.
Dave Mc. is no longer Secretary.

=== via Alberto ===
It would be attractive to have a more advanced--Project KI on having Ben become the Secretary and Travis becoming Director at Large (taking Ben's place).TBUILD sponsored--kit build before or around the 2014 Summer School session in conjunction with an AVR programming-related workshop. '''Please chime-in via the Members list if you feel you can run 2 - 4 workshops on AVR programming''' and you and Project KITBUILD can look into getting a custom PCB manufactured to serve the curriculum. (The Late) Elliot Williams has already expressed that he would be honored to have the Eagle files for his [[Avr2011_kit|AVR project board]] reused or modded. Perhaps his [http://shop.oreilly.com/product/0636920028161.do newly published book] can serve as a course supplement. I'm pretty sure I can finagle an instructor copy from Make Books gratis.

HacDC is in the process of refurbishing a scanning electron microscope: a Cambridge Stereoscan 200.

[[File:SEM_install_1_thumb.jpg|right|SEM in workshop]]

=Current Status=

March 30th: Moving complete! The SEM is now in the workshop

March 29th: Awaiting pick-up and installation (March 29th and 30th).

March 23rd: A space in the workshop has been cleared. Photo: http://i.imgur.com/BDNWL5z.jpg

Maintenance and repair logs will be kept on an ongoing basis. For previous status and repairs, see:

* The original S200 operating instructions will be available at the space in a three-ring binder near the machine.

* If possible, members will also have access to a PDF copy of ''Scanning Electron Microscopy - A Student's Handbook'', 1980, self-published by Michael Postek, et al. This book was widely used by microscopists and is still regarded as a good learning reference, but the original binding is rare and prone to falling apart. It might be possible to use the PDF copy for private, educational use.

Annual Meeting 2014

2014-03-12T01:19:25Z

Gatohaus: Secretary's notes.. please feel free to correct or add things that occurred but were missed.

[[Category:Meeting Minutes]] {{TOCright}}
== Purpose ==

From the HacDC Bylaws, Article III, Section 2:
:At the annual meeting, the voting members shall elect the Board of Directors, review and vote on the standing rules and policies of the corporation, receive reports on the activities of the corporation, approve the budget and determine the direction of corporation in the coming year.

This meeting will also serve as the monthly meeting for the month of March.

== Time and Location ==
March 11, 2014

Meeting called to order at 1955 by Ben.

Members Present: Ben, Katie, DavidMc.. 12 in person, 3 online.

Others Present: ~5

[[Quorum]] met? Yes.

== Approval of Previous Meeting's Minutes ==
[[Regular Member Meeting 2014 02 11]]
- approved.

== Recognition ==
* Thanks to Evan and Zack for their work on the laser cutter.
* Everyone involved in Project SEM .
* David McInnis for adding really cool lighting to the new shelves in the basement.
* Julia Longtin (aka. juri) for more 3D printer tweaking and getting ahead on cleaning up the space.

== Director Reports ==

=== President's Report ===
As reported last month, the BoD has approved accepting the donation of a Scanning Electron Microscope (SEM). The SEM is now ready to be picked up and we have about three weeks to collect it. It is currently in Norfolk, VA and is a large, heavy piece of equipment. We will need to rent/borrow a truck (ideally one with a lift-gate) to transport it up to HacDC, and we'll need several strong volunteers to help us load, and unload the truck (including bringing it up the stairs and into the workshop). Additionally, we will need some help making space for it in the workshop. '''We are currently shooting for Saturday, March 29th.'''

=== Vice President's Report ===
admin team is accepting donations of gigabit network switches. we need both managed and unmanaged switches. one managed switch with 20+ ports which is for the church network.
we are getting the space wired for gigabit ethernet so cat5e and cat6 keystone jacks and and wall plates are welcome.

=== Treasurer's Report ===
Here is the financial summary spreadsheet for February 2014: [[File:HacDC_Financials_2014_02.pdf]]. We gained two members in the last month: Elizabeth Smith and Ariam Mogos. We lost two members in the last month: Tim Dixon and Nick Mapsy. We have 46 dues-paying members in good standing, two permanently dues-waived members, four temporarily dues-waived members, and five members who are behind on dues.

==== Project Awesome ====
Here is the Project Awesome spreadsheet for February: [[File:HacDC_PA_Projects-2014_02.pdf]]. Once again we are in the red for the month, so there is no Project Awesome dividend. :(

=== Secretary's Report ===
NonHacDC calendar is being populated. Need to put it in a more public place and open it up to members for editing.
Otherwise nothing significant to report.

=== Director-at-Large Reports ===
No report.

== [[:Category:Project_Awesome|Project Awesome]] Reports ==

=== Project LASER ===
Dan: Optical maintenance; cleaning lenses, tightening things, etc. Found the aluminum track is wearing and has some play. Will try to flip them to use the other side, otherwise will purchase new tracks. This is expected, normal wear.
Aiming laser and combining optic is here, but dust is still a problem. Will add air flushing to all optical components.
Thanks to those who worked on the alignment.
The idea of having jigs underneath is being put off. The cabinet will need to be reworked first.

=== Project BYZANTIUM ===
Nothing new to report.

=== Project KITBUILD ===
Nothing new to report.

=== Project SUPPLIES ===
Still healthy and stable. A few expenses this month, related to lighting the new shelves.

=== Project EXPANSION ===
We may be able to afford a small vertical bandsaw for about $100, similar to the one we had before. This would help cutting stock materials for CNC mill, laser cutter, photolithography fab, etc. Any suggestions or objections?
Dan: reminds Mirage that we'd like ink for the inkjet plotter in the basement.

=== Project SPACECAM ===
Kevin: comments on Rob's donation list, very interested in the projectors and the scanning/projecting white boards.
WebRTC is what will hopefully replace Hangouts in the future. Please check it out.

== Member Reports ==
=== Justin Myers ===
Quick reminder that our first [http://larcmd.org/vec/ Laurel]-accredited ham radio licensing [[Licensing Exams|exam session]] starts at noon [http://www.meetup.com/hac-dc/events/160901402/ March 22] (a week from this coming Saturday). Review/questions are welcome at tomorrow's (March 12) HARC meeting.

If you're interested in getting licensed, take your exams here for free! Other exam dates this year: [http://www.meetup.com/hac-dc/events/160901522/ June 21] and [http://www.meetup.com/hac-dc/events/160901572/ Nov. 8].

We also need more examiners who can help out at these sessions; if you're already licensed (General or above) and want to help, let me know.

=== Mirage ===
Audio difficulties.

From chat: Basically, I have a nice HF antenna, and continuing work with Imagnus. The USRP is cooperating now. Would like Dan and I to have permission to expediently dispose of remaining junk in the basement. Three months is far too long!

=== Dan ===
New acrylic colors in stock. Non-rastering cutting is working fine (laser cutter).
Discussion: computer for laser cutter could use more memory, but it's windoz XP. Options presented, will look into it.

== Old Business ==
Provide Martin a keyholding honorary (nonpaying) membership.
- Approved by member vote.

== New Business ==
Approve Article IV of the [[Proposed_Standing_Rules#Article_IV:_Meetings|Proposed Standing Rules]]. This codifies our existing policies and empowers the BoD to reschedule member meetings for the following week in the event that an emergency (such as weather) forces the cancellation of a scheduled meeting.
- proposed rules reviewed in meeting, minor discussion followed
- Approved by member vote.

Permit Dan Barlow and mirage335 to expediently dispose of junk in the basement for the next few months.
- Approved by member vote.

I'm a senior imaging scientist (or so said my job title) looking to find creative types (art, science, tech, or "wild cards") to fulfill the social void that seems so common these days. My background is in theatre, photography, astronomy instrumentation, image processing and, most recently, long wave hyperspectral imaging.

== Project Ideas ==
; Soft boiled egg cooker
: small temperature controlled water bath
: hold somewhere between 1 and 4 eggs
: temperature of 160F with <2F error/flucuation

; Search for non-G,A,C,T based life
: very little research has gone into looking for different forms of life here on Earth
: most of what searching has been done would only be able to detect the kinds of life we're already familiar with
: the ubiquitous assumption is that there is but one Darwin-esque tree of life.. but there's nothing to have prevented multiple trees from sprouting, actually it would be strange if there was only one
: I have no ideas on how to start such a search and my skillset has little to do with such things, which makes it sound like more fun

== Organizational Ideas ==
* organize wiki pages containing rules and such
*: considered also moving rules and meeting pages to their own namespace.. too much effort
* calendar of non-hacdc events from around the region
*: Started, see http://jbwa.net/HacDC.php
* tweak wiki's css: headings, background, whitespace honoring

== Sparsely sampled journal ==
=== 14 Feb 2014 ===
* Lighting for the new shelves in the basement are functional.
*: Need better power supply and to tidy things up a bit.

=== 17 Mar 2013 ===
Thanks to the instructions here ([[PrusaMendel]]), I've been able to try a couple of prints. Lots to learn, from CAD software to maintaining the printer.

=== 12 Mar 2013 ===
For some reason I stepped up to be Katie's replacement as secretary, as she becomes treasurer.

==Ancient==
=== 22 Jan 2013 ===
We've recently moved from Old Town to Mount Pleasant, about 5 blocks from HacDC. :-)
So maybe I'll actually be able to do stuff at Hac now.
I'm interested in learning how to use the 3D printers, for a start.

=== 09 Nov 2010 ===
Became full HacDC member. Started paying and received approval at member meeting, [[Regular Member Meeting 2010 11 09]]. Received key to space.

=== 05 June 2010 ===
My wife and I went to the last lightning talks (June 2010) and were pretty impressed.
I have a project I'd like to work on (and would welcome help from someone interested in machining or programming) but am unsure of how to 'jump in' to [[HACDC]].
The project is not wholly new, but is uncommon enough to be interesting (to me anyway). It's to transform a flatbed scanner into a large format scanning back for an 8x10 camera. There's a secondary project of transforming a scanner into a portrait camera.

...hmmm, why am I writing this on my user page, this should be under proposed projects....

<s>Also, I recently started helping out an artist, [http://www.RosemaryCovey.com RosemaryCovey], at the [http://www.torpedofactory.org/ Torpedo Factory] with the technical side of her creations. We're heading toward forming a group that blends art and science in an attempt to de-isolate these communities. We are still shaping the idea and looking for interested people (we just started at the end of May 2010).</s> Rosemary suffered a major loss, this idea had to be dropped.

Gatohaus: Added before and after pic.

[[Category:BasementShelves]]

[[File:Shelf lights v0.9.gif|Before and after, same exposure|right]]
==LED Lighting==
Feb 2014: LED strips have been added to the underside of each shelf by [[User:Gatohaus|Gatohaus]] ([[User talk:Gatohaus|talk]]).
These are SMD 5050 strips, 5m long, 300 LEDs each that draw 1.2A per meter at 12v. Note they have been trimmed nearly a foot each to fit.
Total maximum wattage for the 10 strips currently in place is 10 x 72w = 720w. Output is around 800-900 lumens per meter. (~40k lumens)
A good balance between light and heat (longevity) seems to be in the 3 to 4A per strip range.

The location of the strips was chosen: to be somewhat protected, to light the shelf adequately, to avoid as much glare as possible, and to provide significant spillage into the surrounding area.

Feb 2014: '''Expect a few of the strips to fall down.''' Some are still partially attached by their adhesive tape which won't really fail until they're warm for a while. When they do fail, reattach them with a hot glue gun. That seems (fingers crossed) to be permanent.

=== <u>Lessons Learned</u> ===
==== Strip Choice ====
SMD 3528's were also tested (the strip remains in use on the shelves). The 5050's were the same price (~$12) at about the same efficiency but allow for a higher maximum brightness (and greater power draw of course).

==== Adhering the strips ====
The tape adhesive that comes on the strips works very poorly on OSB (shelving material used). They'll hold while the lights are off, but once they warm up the adhesive begins to fail.
I tried 3M's "77" spray.. an embarrassing failure. It too loses adhesion when warmed.

Trying mechanical attachments, typically a nail or staple with a plastic brace, the type used to hold cables in place, proved troublesome. The OSB is hard enough that significant force is required with a hammer to drive the nails in. Over a span of 50m of LEDs it seems likely that misses would occur probably smashing some of the LED components.

In the end a simple hot glue gun seems to have worked.

==== Wiring & Power ====
In hindsight it would have been better to mount the strips with more of the connecting leads sticking out at the end. The leads can easily be replaced if needed, they're just surface mounted.

<s>I used a PC's ATX power supply which has 2 x 12v at 15A.</s> (I managed to damage this ps somehow.) I don't know how efficient it is but after spending several hours hunting for options in our collection of stuff, this seemed the best choice. Perhaps it can be replaced at some point. I'm giving one of the 15A sources to the lower 3 shelves, and the other to the top two shelves. This means the upper ones will be brighter, but the spill over will help illuminate the surrounding area.

Temporarily (which tends to become permanent) there is another ATX ps plus a couple of in-line wall warts in place of the ATX mentioned above. This ATX has 12v at 21A and the two wall warts have 5A and 2.5A at 12v. Not quite the distribution I'd like, but it works.

'''Well... almost works...''' After being on for half an hour or so the 21A ATX takes a nap. Exhaust air feels cool, but it's probably too much of a load. So I added ''another'' computer power supply (~5A) to help out. Seems to be stable.
Need help either repairing the original ATX supply or finding something else.

=== <u>Things to Improve</u> ===
In general I'm not exactly proud of the wiring. It's solid and safe, but not quite pretty. If someone wishes to redo this work, please do!

I have a project I'd like to work on (and would welcome help from someone interested in machining or programming) but am unsure of how to 'jump in' to [[HACDC]].
The project is not wholly new, but is uncommon enough to be interesting (to me anyway). It's to transform a flatbed scanner into a large format scanning back for an 8x10 camera. There's a secondary project of transforming a scanner into a portrait camera.

'''When you use the Prusa Mendel, please add notes here. Newest at top.'''

* Thanks for the update. For a mechanical part like that, "Quality" was appropriate. FYI, "Cheap" parts are now just as aesthetically beautiful, but use less and simpler infill to print much faster. Also, uploaded relevant custom hardware files to [https://github.com/HacDC/PrusaMendel github] . With that, the essential modifications to HacDC's printer are now fully documented. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 18:33, 18 January 2014 (PST)

* Printed [http://www.thingiverse.com/thing:216153/ a piece for my Printrbot's new extruder], and all went well. Forgot just how long the "Quality" setting takes, but I had the time to spare. (myersjustinc, 2014-01-13)

* Printer returned yesterday. Applied new double pane glass, alignment is excellent. This means good adhesion across the entire print surface and high resolution output. Also, support material has been configured and tested, enable as necessary. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 13:10, 5 January 2014 (PST)

* New version of pronterface seems to be helping with the crashing. More Slic3r fixes have improved quality for small parts. Delaying printer return until Saturday to test ABS printing, build more spare parts, enable support material, and possibly recompile firmware. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 20:24, 1 January 2014 (PST)

* Maintenance in progress. So far, extruder has been replaced, failed wooden groovemount swapped out for a new aluminum groovemount, bed has been leveled by a printed mat, and various Slic3r tweaks have been applied. End result is '''vastly superior print quality''', probably above what was originally achieved. Unfortunately, pronterface software is now crashing in the middle of print jobs. If this can't be fixed, new firmware will be needed to enable fully embedded printing from SD card. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 11:31, 1 January 2014 (PST)

* Started printing [http://www.thingiverse.com/thing:194956/ an ornament], but I was silly and tried to close Slic3r while the print was going on, so the laptop (and therefore the print) hung. Wasted some time, but the print was going great until then. (myersjustinc 2013-12-16)

* Unfortunately, severe icy weather is keeping me and the filament spools away from HacDC for tomorrow. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 18:06, 7 December 2013 (PST)

* PLA plastic filament, 2 1kg reels, will be delivered to HacDC ASAP, probably this weekend. Vastly improved replacement glass bed finished, leveled, bolted down, tested to 95C, and used to print a PLA object. Similar high-thickness polycarbonate bed also available. ABS printing should now be achievable. Additionally, a replacement polycarbonate groovemount is ready for CNC milling. The net is that Prusa Mendel should return to above factory condition performance within the week. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 11:12, 3 December 2013 (PST)

* Pronterface has had two crashes in the middle of jobs, independent of laptop. Suspect lack of priority to be at fault, increased nice priority to compensate. PLA plastic filament is out, 2 1kg reels are on the way. ABS printing has been tested, however, the bed cannot get hot enough for the plastic to stick (80C achieved, need >105C). Replacement glass bed nearly finished, diamond cutter and dremel glass drilling tools tested successfully. [[User:Mirage335|Mirage335]] ([[User talk:Mirage335|talk]]) 22:30, 25 November 2013 (PST)

* New operating system loaded onto dedicated laptop. Improved stability and speed, dual monitor support, KDE based UI (goodbye unity!) and other fixes. (mirage335 2013-10-29)

* Thank you all for putting the printer to good use. Please note the bed temperature sensor must be properly taped to the glass to work. Smoothing out the tape holding the glass bed helps too. Also, it is normal for starting temperature to be 53C or so, and decrease when fans engage. Finally, a new glass bed has been ordered to alleviate first-layer issues, which largely account for extrusion width problems. (mirage335 2013-10-15)

* Printed a [http://www.thingiverse.com/thing:50544/ simple stand] with similar heated bed issues to my Aug. 14 report, but no issues at all with the resulting print. (myersjustinc 2013-09-30)

* Worked beautifully. (Rob 2013-09-06)

* I've tried several prints over the last two days, with really inconsistent results. It looks to my inexperienced eye like the flow is narrower than it should be. When I checked the Prusa Mendel manual on how to clean the nozzle, it sounded like there were a lot of ways to break it if you do it wrong, so I did not want to try. (Rob 2013-08-30)

* Worked fine; no issues. (Rob 2013-08-22)

* Worked great, but heated bed never got up to temp. (I tend to print with first-layer temps of 0 to avoid the wait, so it didn't hold me up.) Used 55 C set point, got up to 53 before I started the print, but stayed closer to 45 throughout the print itself (about 30 minutes). Otherwise fully operational. (myersjustinc 2013-08-14).

* Cautionary sign added to prevent further bed fouling incidents. Minor softload updates. Travel (non-print) speed increased, first layer extrusion increased slightly. Machine continues operating reliably, printing without user assistance. (mirage335 2013-08-03).

* Dedicated laptop softload updated (mirage335 2013-06-28).

* Old glass bed fractured. Temporarily replaced with another glass pane. Intend to replace with laser cut glass when possible. As seen [http://devdonkey.blogspot.ca/2013/04/custom-heated-build-platform-for-prusa.html here]. (mirage335 2013-06-21)

* Stable. Fire-and-forget. (mirage335 2013-05-31)

* Fully operational. No known problems. (mirage335 2013-05-17)

* New hot end promptly donated by juri. Machine repaired, however, minor X-axis timing belt rubbing and Z-Axis end stop position need to be tested. (mirage335 2013-05-13)

* Bowden extruder tested, with success. However, the hot-end finally clogged, stripping the PTFE tube out of its M6 bolt clamps at the cold end. A second incident ended my patience with the bowden extruder for now. Moreover, unclogging the hot-end was not entirely successful, and that hot-end now needs replacement. (mirage335 2013-05-12)

* Replacement LM8UU bearings applied to X-Axis along with new X-carriage and zip tie X-axis belt tensioner. Performance greatly improved. Y-Axis replacement bearings will be applied soon. (mirage335 2013-05-05)

* Machine operational. Small gear deformed, due to excessive room temperature. Gear replaced, extruder motor fan added to compensate. It is now clear that all three of the recent failures responsible for downtime likely occurred due to excessive ambient temperatures. (mirage335 2013-05-03)

* New part installed. Machine operational. (mirage335 2013-05-02)

* Machine barely functional. Replacement hot-end mount needed, and already CNC milled. Installation will be done ASAP. (mirage335 2013-04-29)

* Machine functional. Still needs new software load and documentation (will be done this weekend). Use with care, and send M92 E855 for accurate extrusion. Also, more plastic as well as replacement and upgrade parts are on the way. (mirage335 2013-04-25)

* Printing new extruder has proven difficult. Borrowing machine temporarily to complete repairs in a reasonable time. ETA Thursday. (mirage335 2013-04-21)

* MACHINE NOT OPERATIONAL. New extruder must be installed and calibrated before machine can be recommissioned. Also, some of the linear bearings are badly worn, and must be replaced soon. On the upside, print bed standoffs have been eliminated in favor of rigid MDF backing. Bed leveling issues are practically eliminated. This dramatically improves print quality, reduces machine wear, and encourages newbie use (mirage335 2013-04-15).

* No one is at fault for the gear failure. Occurred due to unusual slippage of stepper motor faceplate mounting screws, and subsequent poor contact between gears. Easily repaired by printing new gears. Printer will be operational again in a few days. (mirage335 2013-04-10)

* Started to print again after previous issue, and about 30 minutes in drive gear for the extruder chipped, resulting in flecks of red plastic. This led to the larger extruder gear skipping and making a clicking noise. I was able to pause the printer within a few seconds of this occurring. The drive gear now appears damaged and the teeth-skipping problem persists. Settings at the time were 50mm/min. feed rate, recommended slid3r profiles, 175*C extruder temperature, green PLA, 45*C bed temperature. The print was progressing as expected up until that point. (plasma_ 2013-04-07)
:* (warning, newbie response) Maybe 50mm/min at 175C is a bit much? I was using 40mm/min at 185C without problems. Do we have a table of temperature versus feedrate for PLA somewhere? (gatohaus, 2013-04-08)
* Started a print of my own case. With help from eryc and haxwithaxe on IRC, discovered that the fans were causing rippling. Also noted that the PLA is low. Replaced white PLA spool with green. (plasma_ 2013-04-07)
* Printed first piece of my own design. (filter holder for a spectrometer) Printer worked well. Had minor non-stick problem on first layer, but nothing significant. (gatohaus 2013-03-17)
Check whether extruder is sufficiently close to polycarbonate bed. If all else fails (or you don't mind the extra work), just use paper tape. (mirage335)
:* Thanks. And after inspecting the piece and reinspecting the model, I found something I don't understand. [[Image:3DP PELstand printed gatohaus.jpg|200px|right]] The top slots were supposed to be 14mm wide, but they're 11mm. All other dimensions came out fine. I re-checked the model and the STL file in 2 programs, all show the slot as 14mm wide. ??? (gatohaus)
Slic3r sometimes creates perimeters inwards, changing the dimensions of such gaps. The best way to solve this is to adjust the model. If that is not an option, you can reduce "Vertical shells -> Perimeters" to 1, reducing the error. Failing that, printing "Robust" will use no perimeters and solid infill - at the cost of extreme plastic consumption. (mirage335)

* Printer has been working quite well again for a while now. (mirage335, 2013-03-11)

* Been a while. Attempted to print an untested guitar pick model on poly bed, it failed. Switched to trying the old reliable dodecahedron, but it failed similarly. The nozzle was draggin trhough the layers and smushing everything around. Had a print head/print bed collision that unseated the z axis from it's nuts, attempted to re-level the z axis, and I think I did ok. Switched to glass bed, and definitely had less squishing, but the first layer wouldn't stick... I need help. (xaqrox, 2013-02-18)
Sounds like you successfully dealt with some [http://wiki.hacdc.org/index.php/PrusaMendel#Print_Depth print depth issues] and then switched to glass bed. However, the glass bed is finicky about cleanliness, so try again with the polycarbonate bed. Failing that, try paper tape on the polycarbonate bed. (mirage335)

* New software load added to dedicated laptop. Wiki and machinery fully harmonized, efficiency and performance maximized. (mirage335, 2013-02-11)

* Found PSU switched on. (mirage335, 2013-02-07)

* Printed part of an [http://www.thingiverse.com/thing:36321 earbud holder]. Print quality was great--no problems at all. (myersjustinc, 2013-02-04)

* Proper spool mounting system and Z-axis constraints added. Print quality vastly improved. (mirage335, 2013-02-04)

* Attempted to print UCK (universal connector kit) lego to krinkle block adapter with great difficulty due to stl weirdness. printed a whistle instead. it was uneventful. i had the fans peeled back though so i got a bit of droop on the primary hole and the speed (what was it) was a bit fast so it wasn't very tight. (haxwithaxe, 2012-01-23)

* Some problems may be ambient temperature related. When the room is 52F (11C), plastic curling, extruder jams, and Z-axis endstop malfunction are more likely. Placing a space heater on medium heat (~750W) at least four feet from the RepRap helps. Usual concerns about space heaters apply, be safe. (mirage335, 12-31-2012)

* Found loose bolts on end stops. Tightening the bolts and greasing part of the Z-axis endstop switch resolved previously mentioned homing issue. (mirage335, 12-28-2012)

* Machine needed grease. Donated [http://reprap.org/wiki/Lubrication officially recommended grease]. Re-greased linear bearings and Z-axis threaded rods. (mirage335, 12-24-2012)

* Z-axis end stop occasionally deviates from its typical 'double click' homing. This puts it too far above the printbed. Fortunately, this occurs rarely, and may be a software glitch. The workaround is to restart the print job until it works correctly. (mirage335, 12-23-2012)

* Polycarbonate beds provided for RepRap. Glass bed still available. First layer adhesion vastly improved, bed leveling issues now far less critical. Enables easy printing of large (180x180mm) parts. Spare polycarbonate beds are exist, so users need not be too concerned about fouling. Paper tape may be used if necessary. (mirage335)

* Thin paper provided for leveling. Place small strips under print bed to adjust height. (mirage335)

* Existing power supply spontaneously failed in the middle of a job. Cautiously wired up new ATX 12V power supply, with help from juri_ . Also added 120mm fans, with cable ties (semi-permanent attachment) and gator clamps (to allow swinging the fans out of the way). Finally, achieved successful [http://www.thingiverse.com/thing:12925 bridge tests], finding lower extrusion temperatures (165C vs 185C) improved print quality. (mirage335, 11-19-2012)

* A user found the PLA filament almost entirely used up.

* The Z-axis endstop has been moving slightly downward every time it is used. (mirage335)

* Found printer bed deleveled again. Releveled, and now machine is happy-go-lucky. (mirage335)

* Found the glass detached from the heater bed, Z-axis badly askew, and Z-axis end-stop repositioned. Performance degraded to worse than the old makerbot, but was repaired after much wasted plastic and lost time. Also added paper tape to front of printing bed for safety. (mirage335, 9-23-2012)

* Vastly better printing than makerbot. High precision, fast, easy to use, configurable. Extreme objects were tested successfully. (mirage335)

Most ''minor glitches'' were on account of provided USB ''fan''. Overhang is best reduced by filleting[http://en.wikipedia.org/wiki/Fillet_(mechanics)] sharp edges and placing fan a few inches from to printer. However, strong wind may cause unusually tall and thin parts (ie. pencil-like) to print crooked; the fan should be placed at least a foot away in these cases. Fan itself should be externally powered, unplugging it from the laptop USB port disconnects the printer. Unplugging other devices (USB sticks) has no effect. Fan must rest on high-friction (eg. rubber) surface, or will slowly blow itself away. (mirage335, 9-15-2012)

More detailed documentation on the newly built Prusa Mendel (iteration 2). A PC has been dedicated to run it, below you will find the toolchain used to run it and other details that you may find useful.

=Workflow=

CAD/Thingiverse -> Netfabb -> STL -> Slic3r -> Pronterface -> PRINT!

See operation section for a tutorial.

;CAD
: FreeCAD (free, open source) and SolidWorks (expensive, some extra features) offer intuitive sketch and constraint based modeling.
: OpenSCAD uses programming code to describe 3D models.
: And in case you don't want to model anything and simply want to print stuff, go to [http://www.thingiverse.com Thingiverse].

;Netfabb
: software for checking the "3D printability" of the model you created. Go to [http://www.netfabb.com Netfabb] and download the Studio Basic option. You can also simply use their cloud offering and have a repaired model emailed back to you.
: if your model has issues, run the repair function with default settings and see if that remedies the issues. The repair function can be used by clicking the "first aid" symbol found at the far right on the tool bar.

; STL
: current format for 3D printing (AMF is coming around the corner).
: at this point, your file should be patched up and ready to print.

;Slic3r
: software for creating 3d printing toolpaths
: precompiled binaries can be had from [http://www.slic3r.org Slic3r.org] or be built built from [https://github.com/alexrj/Slic3r github].
: use the profiles already generated for best results.

;Pronterface
: GUI for controlling the Prusa.
: where you will connect to the printer, home, warm up and send print jobs from.
: can be built from [https://github.com/kliment/Printrun github] or download precompiled binaries for Windows/Mac [http://koti.kapsi.fi/%7Ekliment/printrun/ here].
: preview G-Code generated by Slic3r.

;Print
: File is good to go, toolpaths are generated, time to let the robot do what it does best, PRINT!

=Materials=
Switching from PLA to ABS, or vice versa, will require purging extruder at with at least one meter of filament at >225C.

Generally, PLA is stronger, better for the environment, and easier to print with. Please use ABS only if there is a specific need for it.

* PLA - Polylactic Acid
: '''Extremely ecologically friendly''', made from corn starch, smells like waffles/syrup while printing.
: Harder than ABS at room temperature.
: Needs a fan for parts with overhang/bridging.
: Recommended solvent for gluing or vapor polishing is tetrahydrofuran. Slightly more hazardous, much more expensive, and less effective.
: Low operating temperature (160C-200C).

* ABS
: '''Much less environmentally friendly.'''
: Weaker than PLA at room temperature.
: Poorer adhesion to bed while printing, may need polycarbonate bed, paper tape, kapton tape, etc.
: Degrades nozzle, forcing more frequent cleaning by an experienced person with blowtorch and acetone.
: High operating temperature (225C-240C).
: Recommended solvent for gluing or vapor polishing is acetone. Low risk, low cost, highly effective.
: Suitable for moderately high-temperature applications like coffee mugs, outdoor fixtures, and certain 3D printer components.

=Extra Maintenance=
==Malfunction==
*Only grease with PTFE SuperLube, kept at HacDC next to printer.
*Grease smooth rods and Z-Axis threaded rod if axes show signs of binding.
*Tighten timing belts if not taunt.
*Floss the hobbed bolt in the extruder.
*Replace linear bearings if they are grinding, slipping laterally, or otherwise ruined.

==Replacing filament/changing spools==
#Turn on the printer, open pronterface, and connect to the printer.
#If there is filament sticking out of the top of the extruder, you'll need to remove it.
#Set the hotend temperature (175-185 degrees Celsius for PLA)
#When extruder is warmed up, raise the extruder (+z axis) so it's not touching the bed.
#Click the reverse button while gently pulling upwards on the filament you wish to remove.
#Continue gently pulling and pressing reverse until the remaining filament is drawn out from the top of the extruder housing.
#Once the filament has been removed, replace the spool.
#Feed the new filament into the appropriate hole in the extruder housing.
#Gently press down on the filament while clicking "extrude" in pronterface. The extruder should grab the filament as you feed it.
#Repeat the previous step until you see the new material being extruded from the tip.
#Sometimes it may be necessary to loosen the spring loaded screws on the extruder, and manually unload/load the extruder.

=Tips=
*'''Always swing fans in during a print. They engage automatically as appropriate.'''
*Time estimate in pronterface's bottom bar is wildly inaccurate. The console printout when a gcode file is loaded will be about 75% accurate.
*Some problems may be ambient temperature related. When the room is 52F (11C), plastic curling, extruder jams, and Z-axis endstop malfunction are more likely. Placing a space heater on medium heat (~750W) at least four feet from the RepRap helps. Usual concerns about space heaters apply, be safe.
*Bare glass bed is best for quality, tightly grips plastic when hot, releases when cold. Paper tape on glass is generally more tolerant to misalignment. Bare polycarbonate provides extremely strong adhesion, too strong above 45C.
*When printing long parts (eg. 150mm*50mm), it it is better to rotate the part, and align its length to the X-axis. The bed is slightly more level along the X-axis than the Y-axis due to a minor design flaw.

=Slic3r Settings=

==Print Settings==
===Cheap===
High speed, low plastic consumption, lightweight part. Also most appropriate for model aircraft parts, as the strength-to-weight ratio is likely approaching that of carbon fiber.

===Quality===
Maximizes quality, strength, and accuracy. Used for Prusa Mendel Replication.

===Precision===
75micron layer height, for parts with smaller features.

==FilamentSettings==
===HacDC===
Optimized for bare glass bed, solid parts, and fast printing. Decrease bed temperature to 45C for bare polycarbonate bed. Decreasing extrusion temperature to 167C may improve bridging but requires slowing down print speed, reduces quality, weakens printout, and may significantly increase extruder wear.

==Printer Settings==
Leave at "HacDC" unless you feel they need debugging.

* 100K Thermistors (extruder an heated bed)

For FW reference on steps per axis: (80, 80, 2560, 855) {X, Y, Z, E}, this is also assuming 1/16th microstepping and 9/47 gears. Old extruder used 666.67steps/mm.

=To Do=
* Tune trimpots on motor drivers
* Print spare parts.
* Experiment with higher supply voltages.

=Known Bugs=
* Model holes will print the wrong size. The proper way to manage this is by keeping about 0.25mm per wall or 0.5mm diameter clearance in CAD models.

=Swapping Materials=
Changing from glass to acrylic or polycarbonate beds is '''easy'''. '''Just remember the following:'''
# For glass, use the laser cut foam washers, and don't over tighten.
# Ordinary glass needs the laser cut plastic as heat spreader and thermal resistor. Not recommended for other materials.
# For plastic (acrylic/polycarbonate), don't set the bed too warm, or the printed part will be non-removable.

The full print bed stackup is:
# Bottom. MDF backing attached to LM8UU bearings and timing belt.
# Printed, plastic, leveling mat. See "Leveling" section below for details.
# Laser cut foam mat. Serves as thermal insulator, provides a notch for wiring, and slightly improves flatness.
# PCB heater.
# Optional. Laser cut red plastic, clear plastic, or silicone. Mostly serves as heat spreader and thermal resistor, sometimes necessary for ordinary glass.
# '''User-selected print surface.''' Glass, plastic, the choices are elaborated in the "Surface Materials" section.
# Foam washers. These are laser cut from the same material as the foam mat, and should not be reused once crushed. Extras are stored in a glass jar.
# M3 screws and washers. These are bolted directly through mounting holes in all other layers, including glass.

=Surface Materials=
By default, we are using an ordinary glass print surface, which has been cut, drilled, and bolted onto the printer. Other surfaces are available, and we plan to upgrade to pyroceramic glass as the default print surface.

==Glass==
Glass is an ideal print surface material. It binds strongly to the plastic while warm, and releases the part once cool. Additionally, glass is somewhat rigid, flattening out the print surface.

Obviously, is all good for first layer alignment, warp prevention, and easy part removal at the end of a job.

'''Please be careful to use the laser cut foam washers for installing glass, and apply as little pressure as possible.''' Tighten all the screws a quarter rotation at a time, just until the glass stops moving downward.

===Ideal Glass Surface===
Pyroceramic Glass, 9" * 9", Four Mounting Holes. Recommend against the [http://devdonkey.blogspot.ca/2013/04/custom-heated-build-platform-for-prusa.html similar bed design here]. The wiring cutout and larger 9.5" * 9.5" size may contribute unnecessarily to thermal stress.

Can be ordered from One Day Glass.

===Ordinary Glass===
Ordinary glass can be purchased from a variety of stores, cut to size, the drilled with a dremel and the cylindrical diamond abrasion tool. After a little practice, new glass beds can be manufactured with just a few dollars and 20 minutes.

Tenleytown Ace Hardware is especially helpful, offering cutting service with the glass.

Unfortunately, ordinary glass does tolerate thermal stress well. Although we are in theory using a PCB heater to evenly warm the bed, in practice the thermal gradient from center to outside edge can be high as 30C. Catastrophic failure becomes likely given mechanical stress, spot heating/cooling from some 3D printed parts, or microfractures on a poorly cut edge. Further, ordinary glass may be less rigid, prone to representing complex warped shapes underneath it.

Ordinary glass surfaces should be double pane and no larger than 8.75" * 8.75" . Optionally add the thin laser cut red plastic, clear plastic, or silicone sheet between ordinary glass and the PCB heater. This will mitigate rapid or uneven heating.

==Plastics==
Plastics tend to offer extremely tough adhesion, without the quick release behavior offered by glass. While this may be helpful at times, care is needed to prevent parts from permanently binding to the print surface, even if paper or kapton tape layers are used.

'''When printing on these surfaces, please set the bed temperature as low as possible. Recommend no more than 45C for PLA.'''

Additionally, plastic surfaces are inherently less rigid than glass, particularly if thinner than ~5mm.

===Heavy Acrylic===
An 8.25mm acrylic sheet has been salvaged from a disassembled LCD monitor, and laser cut to fit. At this thickness, rigidity seems to be exceptional. Probably the best choice for laying down a paper tape or kapton printing surface.

===Polycarbonate===
A 5.75mm polycarbonate sheet has been cut and drilled to fit our printer.

=Leveling=
'''Suggest others do not attempt this without prior experience.''' Anyone contemplating this '''exercise in frustration''' needs a ''lot of patience and a fire extinguisher''. Additionally, the end result is difficult to undo if incorrect.

Built-in alignment between extruder positioning system and print surface is badly warped on our aging Prusa Mendel, taking as many as six polynomial orders to accurately characterize. Consequently, the only reliable process for realigning this complex system is rather complicated, involving a 3D printed and heat-polished leveling mat. It is roughly equivalent to using a CNC mill to finish off its own table.

==Step 1==
Use a CAD program to generate a large rectangular object covering most of the print surface '''at least three layers high'''. This is our 'leveling mat'.

==Step 2==
'''Disassemble''' the print bed down to an '''intermediate surface''' (preferably the hard MDF backing), cover with paper tape. This is the print surface for our 'leveling mat'.

==Step 3==
Carefully '''move the Z-axis endstop''' to match extruder depth with the new print surface.

==Step 4==
'''Abort'''! If you have started printing the leveling mat, you probably didn't set the Z-axis endstop position well enough. When this happens, do not wait for the printer to put down more than one layer of the leveling mat - it may become infeasible to remove.

Use '''PLA material''', and '''retry printing''' the leveling mat until the first layer is clearly adhered to the intermediate surface.

==Step 5==
There will be some rough areas on the printed mat. '''Heat polishing solves that.''' Bolt the PCB heater on top of this leveling mat, bolt laser cut foam on top of that, and the heavy acrylic print surface on top of that. Ensure the whole assembly is evenly clamped down under significant pressure.

Heat to ~90C for 5 minutes, and '''have a fire extinguisher handy'''. Generally, when the underside of the MDF hits 40-50C, heat polishing will be complete.

==Step 6==
Unbolt the heat polishing assembly, and check the leveling mat. Should be '''silky smooth''', with no bumps larger than 0.05mm. If not, repeat Step 5 until it is.

==Step 7==
'''Reassemble''' the print bed as it was before, carefully. If lucky, it should be possible to keep extruder nozzle aligned to print surface within <0.15mm at all positions.

If unlucky, not only will the print surface remain warped, but the old leveling mat will need to be removed to repeat the process. Since the leveling mat can adhere very strongly, this can be excruciatingly difficult.

2) If you used [[User:haxwithaxe|haxwithaxe's]] image then skip this step else read on.
The default image is missing some rather important bits like the terminal activity and the means to install it. To install any activity go [http://wiki.laptop.org/go/Activities here] and write down the url for the .xo file of the activity you want and then get to the virtual console by pressing ctrl+alt+<first gradiated circle key> (the gradiated circle keys and the volume/brightness keys are mapped to the function keys). Then wget the .xo from the url '''without the http://''' (damned if I know why :/ ), run "sudo apt-get install unzip", then unzip the .xo and place the resulting <activity name>.activity folder in "/home/olpc/Activities/".
To get back to Sugar press ctrl+alt+<a gradiated circle key> ... i say "a" because it's one of them but i can't tell which one. Just press each one successively until Sugar pops up.

3) Go wild with it it's full on Debian :P If you want you can follow the [[OLPCSoundmodem|Soundmodem]] and make obnoxious noises :) or one of the other OLPC specific how tos on this wiki.

'''When you use the Laser Cutter, please add notes here. Newest at top.'''

* 18 Oct 2013: [[User: rob]] experimented with engraving some black-and-white images on acrylic and cut some acrylic for a project. The Full Spectrum LLC print driver just gave me error messages and I couldn't figure out the problem, so I just converted my images to BMP and that worked fine. It may be of interest that I have found that cutting 0.177" thick acrylic reliably takes 10-11 passes at 100% power, 100% speed. 10 passes leaves some small chads at the edges that are brushed off pretty easily; 11 generally cuts it clean.

* [[User:Haxwithaxe]] made acrylic PentaGo board parts. [https://github.com/haxwithaxe/pentago-flat design]. i forgot to record the time used.
** i used some of the red plastic that was next to the table and it made sort of a cotton candy like material when lased so we might want to figure out what it is exactly.
