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

* 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)

* 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)

Talk:Process for manually installing Byzantium.

Why not include the commands for:
*You've checked the Porteus .xzm modules we built for Byzantium out of SVN, installed, and enabled them.
*You've checked the source tree for Byzantium out of the Git repository.

Also, if porteus doesn't provide sudo, then... you must be root? In that case why not just omit "sudo" and note at the beginning of the page that you must be root?

And THEN, if all that is ok, why not just line them all up in a script and say "hey, download and run this script as root on a clean install of porteus!"

Makerbot Howto / Tutorial

2011-09-20T00:16:04Z

Xaqrox: /* Set up the Software Side */

=== Overview ===

Before you start, it's nice to have the big picture. Here's an outline of the steps that you'll be taking, and why you take them.

* Download the replicator-G software that controls the machine.

* Download/create a 3-D model in .stl format.

* Using skeinforge, (some python routines bundled with replicator-G) turn the 3-D model into a toolpath for the bot's extruder head to follow. At this point the toolpath will be in an industry-standard text format called "gcode".

* Warm up the machine. (You could have been doing this all along...)

* Convert the gcode into the makerbot's native format (.s3g) and send it across. This is done transparently in one step when you press the "Build" button.

* Confirm that the test extrusion worked.

* Watch it print. Let it cool a bit when it's done. Hooray!

The rest of this page is a step-by-step that you can follow. Enjoy.

=== Set up the Software Side ===

Get your bits set up.

* Download the latest version of replicator-G: [http://replicat.org/ replicat.org]

* Run it at least once. It creates a secret .replicatorg directory in your home directory.

* Replace the ~/.replicatorg/machines.xml file it creates with the one found here: [[Makerbot machines.xml]]. If you don't do this, you will '''fail''' when using the makerbot in the space. (Ugh. They've moved the location of the machines.xml file in version replicatorG-0022. The path to machines.xml will depend on the version you install. Placing "machines.xml" into the "machines" directory in the install directory seems to work.) You will know you have it right when you see "Andy Walker's Cupcake with 4 axis board" in the Machine...Driver pulldown menu. (Current as of Jan 2011)

* Download something fun to print. If this is your first time, something cool but quick like the [http://www.thingiverse.com/thing:1813 penny bottle opener] or a [http://www.thingiverse.com/thing:198 dodecahedron] is a good idea. You should now have a .stl file.

* Open up your .stl file in replicator-G. You should see a 3-D representation of it on a wireframe of the build platform. If it's too big, scale it. I always press "Move...Center" which puts the object on the build platform for you.

* Feel free to follow the [http://replicat.org/usage replicator-G usage tutorial], but start the machine warming up first. (Next step.) That way, the ten minutes you spend monkeying with replicator-G will serve double-duty as time warming up the machine.

=== Fire up the Machine ===

Here we connect to the machine, and start it warming up.

* Make sure the power switches on the power supply and the bot itself are flipped on.

* Plug in the USB cable that's coming out of the Makerbot.

* Select Machine...Driver and choose Andy's Cupcake. (You _did_ replace the machines.xml file in the step above, right?)

* Select Machine...Serial Port and choose /dev/ttyUSB*

* The top bar should now be green and the machine's name ("Slick") visible. If not, try clicking on the disconnect and re-connect icons. The next time you connect, replicator-G will remember these settings and it should just connect automagically.

* The four-way arrow icon opens up the Control Panel. Do that.

* On the right-hand side are controls for temperatures. Since it takes a while to heat up, we're going to pre-heat the machine now. Set the extruder temperature for 220 and the build platform for 100 (celcius). You will need to wait at least 5 minutes (maybe 10) until it's ready to go. _DO NOT_ start extruding when the extruder temperature gets up to 220 -- the thermistor is on the outside of the barrel and it heats up before the plastic is melted. You need to wait another five minutes after it says it's at 220.

* On the left are the platform controls. Honestly, it's easiest to zero the machine by hand. Press the "Set Zero" button. Now, push the platform so that the nozzle is in the center, and using the crank on the top right of the machine, lower the nozzle until it's almost touching the platform (0.1-0.2 mm above).

* (Optional manual test extrusion) If it's been at temperature for more than five minutes already and the extruder head is good and hot, you can raise the nozzle (press z+ to step up 10mm) and do a test extrusion. Type "255" into the PWM box at the top right, and select "Forward". In a few seconds, you should see hot plastic noodle extruding. Congrats. Now press "Stop". If you do a test extrusion, be sure to place the nozzle back down at zero when you're done.

=== Build the G-code for your Model ===

G-code describes the path that the extruder head needs to follow to make your object, along with temperatures and motor speeds and other necessary details. Skeinforge is the program that turns your 3-D model into the g-code tool path for the machine. (This is where many bodies are buried.) Skeinforge is part of the replicator-G package that you've already downloaded. You're gonna need to click some buttons.

[[Media: cupcake_raftless.tgz]]

* While the bot is warming up, press the "Generate GCode" button. It will open up a dialog box with a choice something like "cupcake-mk4-heated-platform-abs". Select that. Check the "Use raft" checkbox if it's not already.

* For now, we'll be using the vanilla settings, but if you were going to change some of the skeinforge parameters, you'd click "Edit" or "Create" to edit or duplicate and edit the skeinforge settings to your liking.

* OK, I lied. There's one setting you might want to change. (Optional.) With "cupcake-mk4-heated-platform-abs" selected, click "Edit" and then "Raft". Set "Interface Layers" to 1. Press save and close.

* Back at the first menu, pressing "OK" will start compiling. This can take a while. Good thing the machine is warming up... Pace around expectantly for a few minutes.

* When it's done, you should have a tab labelled "gcode". Click it if you want to see what gcode is like.

* The leftmost button on the top row (arrow pointing to a ghostly jelly bean) enables you to simulate the build. Click it, wait a few seconds, and then watch as it traces out the planned object path. Cool, huh? This will be an important pre-flight check in the future, once you get used to what it means.

=== Print ===

Here goes nothing...

* Are you ready to rumble?

* Has the extruder heated up? When you see a little bit of plastic oozing out from the tip of the extruder, you know you're ready. (Feel free to re-open the control panel to check that it's at temp for a while.)

* Does the machine think it's at zero? (Feel free to re-open the control panel and press "Set Zero" again.)

* Is the nozzle physically at zero? (Move the nozzle to the center of the platform, almost touching.)

* Press the arrow-pointing-to-solid-jelly-bean button ("Build") to start the build!

* The nozzle will rise up. In a few seconds, it will run a test extrusion. If it worked, pull the extra plastic off of the extruder and click "yes" and it will start the print in earnest.

* (If it didn't extrude, you'll need to see the section on troubleshooting.)

* The nozzle will move back down to the zero position and it'll start printing out the raft.

* The first layer of the raft is slow and low, and ends up being fat. That's to make it stick better to the platform.

* The next layer (or layers) are skinnier. They're just there to get the height right and the surface level. They will peel off your model when it's all done.

* Watch in amazement for a few minutes. It's neat.

=== While Printing... ===

You're going to have some down-time here. Feel free to grab a drink. But don't stray too far from the machine. It needs babying.

* First thing to check is that the filament is unspooling properly. Sometimes it kinks up. You may want to rotate the whole reel until there's a decent amount of slack for insurance. (Mostly historical -- the current skate-bearing spool has not failed yet.)

* Smell that? That's the smell of melting ABS in the morning. It's probably toxic. Don't inhale directly above the machine.

* Is everything sticking to the platform? Are the platform lights going on and off? These are good signs. It means the heater's working and around the right temperature.

* Is the raft peeling up and jamming the head? Press stop. Do over from the pre-heat instructions onward. This time, you might try putting the nozzle closer to the platform, which can help. Of course, too close and it won't extrude right. The raft will also peel if the build platform is not yet up to temperature. Check that it's hit 100C.

* Listen to the noises. It'll change when it transitions from a solid layer to a fill layer as the pattern changes. Get to know these noises and you won't have to watch it so closely.

* Relax. It takes a while.

* When it's done, wait another minute or so for the part to cool down.

* Sometimes you'll need to peel it off the platform. I use a tiny screwdriver tip under the raft corners.

* Peel off the raft from your part.

* Feel free to trim off the excess plastic bits that inevitably stick out. Diagonal wire cutters are good for this.

* You win. Nice part.

* You can stop here, or download another file and repeat. If you're a tuner (and you know if you are) read on.

=== Writeup ===

* Head on over to [[Makerbot Operators Log]] and write up what you've done. Heck, include pictures if you're feeling swanky.

* Did the machine work? Did it have troubles in places? What was non-intuitive? We want to know!

=== Advanced Tricks for Your Second Print ===

There's a bunch of options in rendering to g-code that you may be interested in changing. You should probably preview your model before printing it out. Read this section while you're watching it print, but don't change anything until it's done -- there's a glitch where sometimes it will abort your print if you try to render g-code.

* See how it's doing multiple laps around the perimeter? That's a setting in skeinforge. "Fill..Solid Surface Thickness (layers)" I often set it down to 2 instead of the default 3.

* See how much fill it's making? Another setting in Fill. "Infill Solidity (ratio)". The default is 0.20. I usually use 0.15.

* If the raft took "forever" and you're impatient, feel free to drop "Raft...Interface Layers" down to 1 or even 0.

* As you saw, there's a billion skeinforge parameters. The defaults aren't bad for most models, but sometimes you'll want to change them, even on a per-model basis. I have more than ten tuned-up skeinforge preference sets. I'll have to share some.

=== Quirks ===

* The z-axis lead screws are modified and super-beefy on Andy's bot. You'll need to modify your machines.xml file to get it to work. See [[Makerbot machines.xml]].

* The motor-driver board is also non-standard now. We're using John Yang's 4-axis motor controller board, which lets us do 1/16th step [http://en.wikipedia.org/wiki/Stepper_motor#Microstepping microstepping]. This means that the steps-per-mm in machines.xml needed to be multiplied by eight relative to the default half-stepping. See [[Makerbot machines.xml]].

* As noted above, the temperature indicated on the nozzle is _not_ the interior temperature that's relevant for melting the plastic, but the exterior temperature right next to the heating elements. You'll need to give it 5 min or so to soak in and melt the plastic.

* The heated build platform solved our problems with the model warping, but getting a raftless print to adhere to the bed is a 50/50 proposition, especially with thin or detailed first layers. (The tip of the [http://www.thingiverse.com/thing:1222 whistle] for instance, is problematic.) Sometimes you can get away with printing onto the Kapton surface, but sometimes you need the blue painters tape for extra adhesion.

=== Troubleshooting ===

Here I list all the things that can go wrong. And they will...

Xaqrox: /* Status */

A new reprap printer will built along the lines of the Prusa Mendel. You can find details of the Prusa design at the [http://reprap.org/wiki/Prusa Prusa Mendel page] on the reprap wiki, or you can [https://github.com/prusajr/PrusaMendel view the sources for the Prusa at github]

=Intro=
Having another 3d printer in the space will allow us to always have a working machine and to use one machine to help fix another if there are problems. It will also enable several people to print things out at the same time. The goal is to document this build so others can make their own printer following our documentation.

=Status=
[[File:prusamendelbucket.jpg|250px|left]]Turns out the Imperial 5/16" washers are not a workable replacement for M8 washers, so we need to get those before the frame construction can begin. Also, we're still waiting on electronics from John.

==John==
1x gen3 mobo
2x gen3 EC
5x steppers
4x stepper controllers (we'll have to pull these from the cupcake and have the cupcake use the mbi ones)
1x p4ac 4 axis stepper controller carrier board (we'll have to pull this from the cupcake too)
1x wade's extruder (assembled and working)
1x 36mm brass barrel
1x 0.5mm mbi nozzle
1x 0.5mm makergear bighead nozzle
Insulator materials (have to make and document on lathe)
nuts/bolts/washers - I have tons
plywood/mdf for build platform

==Still needed==
===Threaded Rod===
We have:
*340x6
*600x2
*480x1
*400x3

How do we make the best use of this?

Or, as per John's suggestion, do we just use 5/16" for the frame and save our 8mm for everything else?

===Heated Build Platform===
If we want it, can get away with some other hacks if we want, or leave it out altogether.
==Offers==
Mark has threaded rod
Alden has a Tiny G board... this is attractive

==Presentations==
===Xaq===
Xaq presented CigLog, a home-brewed cigarette-habit-tracking PHP/MySQL webapp. He talked about the value of social support in trying to create (keep tracking!) or destroy (stop smoking!) habits.

====Xaq's Links====
[http://www.amazon.com/Science-Self-Control-Howard-Rachlin/dp/0674013573 The Science of Self Control] This book is required reading for anyone interested in how habits are formed and extinguished, and the paradox of self control... why is is hard to do things that are good for us (ok, me), and so easy to do things that are bad?

===Bjorn===
Bjorn described working with data from UAVs, which led him to wonder how he could benefit from similar data analysis on his self. He presented an impressive array of projects: GPS logging, using a web notebook to keep track of his thoughts, and a DIY pulse/oximeter (which I, Xaq, saw in prototypical form this past Monday and dang was it cool).

Bjorn metioned a few articles:

*[http://en.wikipedia.org/wiki/Dymaxion_Chronofile Buckminster Fuller's Dymaxion Chronofile]
*[http://www.nytimes.com/2007/10/29/us/29shields.html Obituary of Reverend Robert Shields---the dark side of QS?]

===Erica===
Erica talked about her experience with the Bodybugg, a fitness device that tracks steps and calories. She explained some principles of weight loss, showed some photos and graphs of her results, and talked about some common ideas about weight loss and whether her experience confirmed or debunked those ideas.

[[Media:Bodybugg_Presentation.pdf|Erica's slides]]

===Elephant Ninja (aka Robert)===
Mr. Ninja told us how the disturbing motivational power of video game achievement systems inspired him to implement a similar, low-tech system to help him improve his pull-ups.

http://exrx.net/Lists/Directory.html - the exercise prescription - web-resource for muscles and exercises

===Matthew===
Matthew talked about using engineering principles in the realm of self improvement.

[[Media:DMAIC_Fitness.pdf‎|Matthew's slides]]

===Blue===
Blue told the story of her project to learn guitar the right way - by playing songs and posting them on YouTube as Hello, the Future! She played two songs, one from the beginning of the project, and one from the end, to show her progression.

====Blue's links====
[http://hello-the-future.com Hello, the Future!] - Blue's blog
[http://www.youtube.com/blueinthefuture#p/a/u/3/N0VFQFn7dRI The Songs of the Fifty States] - This video cuts between Blue playing the same song at weeks 1 and 52 of her project.

===Daniel===
Daniel presented his mobile app, ProactiveSleep, which allows the user to track several habits and see correlations between them. He talked about lowering the cost of tracking, and the need for (and seeming lack of) statistcal analysis in self-quantification.

Quantified Self Show & Tell 05/22/2011

2011-05-25T15:06:13Z

Xaqrox: /* Daniel's Links */

We'll meet at 6, schmooze a while, and start presentations around 7.

=Presenters=
'''Xaq Rothman''': Tracking smoking with CigLog, a webapp I wrote.

'''Bjorn Westergard''': Dietary logging with Cron-O-Meter, journaling with tiddlywiki, carrying a gps logger, DIY pulse-oximeter.

'''Erica Kane''': Using a Bodybugg to monitor calorie burn, and to confirm or deny common beliefs about weight loss.

'''Elephant Ninja''': Using the sticker method to track and improve pull-ups.

'''Matthew Velderman''': A total fitness tracking system, including key metrics, the system itself, and outcomes so far. [http://bit.ly/k1pE8e Fitness Tracking Spreadsheet] and [http://bit.ly/jNu2Ae DMAIC Fitness Presentation]

'''Blue of [http://hello-the-future.net hello-the-future.net]''': Every week I sit down with my guitar and make a new song for the internet. In my presentation, we'll hear just how fast a musician can level up in a year.

==What do you track/quantify with?==
Here is an informal/incomplete list of the tools people use that we collected on the whiteboard.

==Presentations==
===Xaq===
Xaq presented CigLog, a home-brewed cigarette-habit-tracking PHP/MySQL webapp. He talked about the value of social support in trying to create (keep tracking!) or destroy (stop smoking!) habits.

====Xaq's Links====
[http://www.amazon.com/Science-Self-Control-Howard-Rachlin/dp/0674013573 The Science of Self Control] This book is required reading for anyone interested in how habits are formed and extinguished, and the paradox of self control... why is is hard to do things that are good for us, and so easy to do things that are bad?

===Bjorn===
Bjorn described working with data from UAVs, which led him to wonder how he could benefit from similar data analysis on his self. He presented an impressive array of projects: GPS logging, using a web notebook to keep track of his thoughts, and a DIY pulse/oximeter (which I, Xaq, saw in prototypical form this past Monday and dang was it cool).

===Erica===
Erica talked about her experience with the Bodybugg, a fitness device that tracks steps and calories. She explained some principles of weight loss, showed some photos and graphs of her results, and talked about some common ideas about weight loss and whether her experience confirmed or debunked those ideas.

[[Media:Bodybugg_Presentation.pdf|Erica's slides]]

===Elephant Ninja (aka Robert)===
Mr. Ninja told us how the disturbing motivational power of video game achievement systems inspired him to implement a similar, low-tech system to help him improve his pull-ups.

==Presentations==
===Xaq===
Xaq presented CigLog, a home-brewed cigarette-habit-tracking PHP/MySQL webapp. He talked about the value of social support in trying to create (keep tracking!) or destroy (stop smoking!) habits.

====Xaq's Links====
[http://www.amazon.com/Science-Self-Control-Howard-Rachlin/dp/0674013573 The Science of Self Control] This book is required reading for anyone interested in how habits are formed and extinguished, and the paradox of self control... why is is hard to do things that are good for us, and so easy to do things that are bad?

===Bjorn===
Bjorn described working with data from UAVs, which led him to wonder how he could benefit from similar data analysis on his self. He presented an impressive array of projects: GPS logging, using a web notebook to keep track of his thoughts, and a DIY pulse/oximeter (which I, Xaq, saw in prototypical form this past Monday and dang was it cool).

===Erica===
Erica talked about her experience with the Bodybugg, a fitness device that tracks steps and calories. She explained some principles of weight loss, showed some photos and graphs of her results, and talked about some common ideas about weight loss and whether her experience confirmed or debunked those ideas.

[[Media:Bodybugg_Presentation.pdf|Erica's slides]]

===Elephant Ninja (aka Robert)===
Mr. Ninja told us how the disturbing motivational power of video game achievement systems inspired him to implement a similar, low-tech system to help him improve his pull-ups.

Xaqrox: /* Presentations */

We'll meet at 6, schmooze a while, and start presentations around 7.

=Presenters=
'''Xaq Rothman''': Tracking smoking with CigLog, a webapp I wrote.

'''Bjorn Westergard''': Dietary logging with Cron-O-Meter, journaling with tiddlywiki, carrying a gps logger, DIY pulse-oximeter.

'''Erica Kane''': Using a Bodybugg to monitor calorie burn, and to confirm or deny common beliefs about weight loss.

'''Elephant Ninja''': Using the sticker method to track and improve pull-ups.

'''Matthew Velderman''': A total fitness tracking system, including key metrics, the system itself, and outcomes so far. [http://bit.ly/k1pE8e Fitness Tracking Spreadsheet] and [http://bit.ly/jNu2Ae DMAIC Fitness Presentation]

'''Blue of [http://hello-the-future.net hello-the-future.net]''': Every week I sit down with my guitar and make a new song for the internet. In my presentation, we'll hear just how fast a musician can level up in a year.

=Recap=
==What do you track/quantify with?==
Here is an informal/incomplete list of the tools people use that we collected on the whiteboard.

Prusa Mendel Documentation

2011-05-24T14:57:04Z

Xaqrox: /* Threaded Rod */

A new reprap printer will built along the lines of the Prusa Mendel. You can find details of the Prusa design at the [http://reprap.org/wiki/Prusa Prusa Mendel page] on the reprap wiki, or you can [https://github.com/prusajr/PrusaMendel view the sources for the Prusa at github]

=Intro=
Having another 3d printer in the space will allow us to always have a working machine and to use one machine to help fix another if there are problems. It will also enable several people to print things out at the same time. The goal is to document this build so others can make their own printer following our documentation.

Or, as per John's suggestion, do we just use 5/16" for the frame and save our 8mm for everything else?

If we want it, can get away with some other hacks if we want, or leave it out altogether.

Having another 3d printer in the space will allow us to always have a working machine and to use one machine to help fix another if there are problems. It will also enable several people to print things out at the same time. The goal is to document this build so others can make their own printer following our documentation.
