== Introduction ==

Big Blue Button is an open source communication framework that allows for video-conferencing and more. It would allow this hackerspace to host video conferences for other hackerspaces/makerspaces and organizations which would further enhance our ability to communicate and share resources.

[https://www.youtube.com/watch?v=6Saztv2WlKI Watch this video for a full introduction]

== Infrastructure ==
We will be using a high-cpu Digital Ocean droplet 8GB Ram/50GB SSD/4 CPUs. This was presented as a viable option by a very helpful Fred Dixon from Blindside Networks.

We will use chill.hakely.org as our domain name until another more-appropriate domain name is decided upon.

== Software Installation ==

How Stepper Motors Work

source: [http://www.imagesco.com/articles/picstepper/02.html http://www.imagesco.com/articles/picstepper/02.html]

Stepper motors consist of a permanent magnetic rotating shaft, called the rotor, and electromagnets on the stationary portion that surrounds the motor, called the stator. Figure 1 illustrates one complete rotation of a stepper motor. At position 1, we can see that the rotor is beginning at the upper electromagnet, which is currently active (has voltage applied to it). To move the rotor clockwise (CW), the upper electromagnet is deactivated and the right electromagnet is activated, causing the rotor to move 90 degrees CW, aligning itself with the active magnet. This process is repeated in the same manner at the south and west electromagnets until we once again reach the starting position.

[[File:stepper_motor_01.gif]]

In the above example, we used a motor with a resolution of 90 degrees or demonstration purposes. In reality, this would not be a very practical motor for most applications. The average stepper motor's resolution -- the amount of degrees rotated per pulse -- is much higher than this. For example, a motor with a resolution of 5 degrees would move its rotor 5 degrees per step, thereby requiring 72 pulses (steps) to complete a full 360 degree rotation.

You may double the resolution of some motors by a process known as "half-stepping". Instead of switching the next electromagnet in the rotation on one at a time, with half stepping you turn on both electromagnets, causing an equal attraction between, thereby doubling the resolution. As you can see in Figure 2, in the first position only the upper electromagnet is active, and the rotor is drawn completely to it. In position 2, both the top and right electromagnets are active, causing the rotor to position itself between the two active poles. Finally, in position 3, the top magnet is deactivated and the rotor is drawn all the way right. This process can then be repeated for the entire rotation.

[[File:stepper_motor_02.gif]]

There are several types of stepper motors. 4-wire stepper motors contain only two electromagnets, however the operation is more complicated than those with three or four magnets, because the driving circuit must be able to reverse the current after each step. For our purposes, we will be using a 6-wire motor.

Unlike our example motors which rotated 90 degrees per step, real-world motors employ a series of mini-poles on the stator and rotor to increase resolution. Although this may seem to add more complexity to the process of driving the motors, the operation is identical to the simple 90 degree motor we used in our example. An example of a multipole motor can be seen in Figure 3. In position 1, the north pole of the rotor's permanent magnet is aligned with the south pole of the stator's electromagnet. Note that multiple positions are aligned at once. In position 2, the upper electromagnet is deactivated and the next one to its immediate left is activated, causing the rotor to rotate a precise amount of degrees. In this example, after eight steps the sequence repeats.

[[File:stepper_motor_03.gif]]

The specific stepper motor we are using for our experiments (ST-02: 5VDC, 5 degrees per step) has 6 wires coming out of the casing. If we follow Figure 5, the electrical equivalent of the stepper motor, we can see that 3 wires go to each half of the coils, and that the coil windings are connected in pairs. This is true for all four-phase stepper motors.

[[File:stepper_motor_04.gif]]

However, if you do not have an equivalent diagram for the motor you want to use, you can make a resistance chart to decipher the mystery connections. There is a 13 ohm resistance between the center-tap wire and each end lead, and 26 ohms between the two end leads. Wires originating from separate coils are not connected, and therefore would not read on the ohm meter.

=About My Interests=
I started flirting with Python in 2011 (I remember the joy in successfully executing my first Fibonacci function). I taught myself objected oriented programming
through PyGame and started dabbling in VR (Oculus DK1 + Unity) and 3D Printing/Scanning in 2013-2014. I took four CISC-related courses at my university: Intro to Problem-Solving (C),
Object-Oriented Programming (Java), Discrete Mathematics, and Information Security (PHP, Linux). I now develop software professionally (mostly web development).

Mechatronics is a new chapter in my life. It is already the most rewarding form of creation that I have ever experienced... 3D printing gave me an initial taste of this experience in 2014,
but I didn't realize my own ability to give life to inanimate shapes; until now. I am ruthlessly dedicated to my passions, and seek professionalism in every opportunity. I welcome collaboration
and am thankful for the sanctuary that HacDC provides for us like-minded individuals.

Lulzbot Instructions

2016-10-07T14:51:44Z

Zhuberty: Added categorization for lulzbot instructions

[[Category:3D_Printing]]
[[Category:Equipment]]
[[Category:3D_Printers]]
[[Category:LulzBotMini]]

Basic instructions for the HacDC '''Lulzbot 3D''' printers

== Create a model with CAD software ==

Create your model with [http://www.implicitcad.org/ ImplicitCAD] or [http://www.openscad.org/ OpenSCAD]. Creating your model is beyond the scope of this document, but the two previous links include documentation. The model will be saved with the extension or '''.escad''' or '''.scad''' respectively.

== Export CAD model to a STereoLithography (STL) file ==

Your model should then be exported as a [https://en.wikipedia.org/wiki/STL_%28file_format%29 STereoLithography file] with the extension '''.stl'''. OpenSCAD can do this from the '''File -> Export''' menu. ImplicitCAD appears to use a separate program:

== Export STL file to G-code printer instructions file ==

While the '''.escad''' and '''.scad''' files are unique to the apps above, the '''.stl''' file is a standard understood by many programs. Some(?) printers understand STL files directly. Our Lulzbot printers are not among them. The STL file must be further converted into a series of instructions that tell the printer exactly how to calibrate, heat, move, extrude, and cool.

Again there is a widely used standard: [https://en.wikipedia.org/wiki/G-code G-code]. G-code files, logically enough, typically have the extension '''.gcode'''. [https://www.lulzbot.com/cura Cura], among other programs, reads STL files and produces G-code files. [http://slic3r.org/ Slic3r] is another such program. (See the [http://manual.slic3r.org/ Slic3r manual] for more info.)

<div style="background-color: #ffff7f; color:#ff0000; font-weight:bold; margin:40px; padding:20px; font-size:120%; border: 1px solid #ff0000;">Use Lulzbot's Cura, not "standard" Cura! The link above will take you to the right place.</div>

== Finally! From virtual to physical. PRINT! ==

# Turn computer and 3D printer on.
# After boot, login as '''root'''. The password is printed on the monitor.
# Insert USB stick (or get your '''.gcode''' to the computer by other means).
# Start '''pronsole'''.
