== Usage and Workflow ==
== Usage and Workflow ==
The 3D printer is controlled via the desktop computer set up next to it. The basic workflow is this:
The general process for 3D printing is outlined below. Please see the individual printer pages for full details.


# Take a 3D model and convert it to an STL file.
# Convert 3D model to STL or download an STL file from online.
# The STL file then must be converted to GCode.
#* https://www.printables.com/
# The GCode is sent to the printer for printing.
#* https://www.thingiverse.com/
#* etc
# "Slice" the STL file to generate GCode (or resin printer file).
# Prepare the printer
#* Load filament
#* Clean/level the bed
#* Change nozzles if needed
# Send the GCode to the printer.
# Monitor the printer until the print is completed.


=== 3D Modeling/STL creation ===
=== 3D Modeling/STL creation ===


We have three CAD programs installed for creating 3D models. Two rely on the principle of [[wp>Constructive solid geometry|Constructive Solid Geometry]] (CSG).
We currently recommend [https://www.solidworks.com/solution/3dexperience-solidworks-makers SOLIDWORKS for Makers] or [https://www.alibre.com/atom3d/ Alibre Atom3D] which are both available on the laser-room computer. Autodesk [https://www.autodesk.com/products/fusion-360/personal Fusion 360] offers a free license for hobbyist use. [https://www.onshape.com/ OnShape] offers a free online CAD editor (note: all free OnShape models are publicly shared).


* [http://openscad.org/ OpenSCAD] is the more mature of the two programs. It uses a scripting language to define a model using CSG.
Other options which are FOSS include:
* [http://www.mattkeeter.com/projects/antimony/3/ Antimony] is a new program, released in Spring 2015 as a visual approach to CSG. While it is easier to use, its STL export is considerably cruder (it uses a naive algorithm for creating models).
* [http://openscad.org/ OpenSCAD] uses a text-based scripting language to define a model, making it distinct from other CAD software. It is great for making parametric parts, where a user can easily modify critical dimensions.
* [http://www.mattkeeter.com/projects/antimony/3/ Antimony] is another procedural modeling software, which uses an interconnected graph of nodes to define geometry (rather than plain text). It is no longer receiving updates.
* [http://solvespace.com/ SolveSpace] is a constraint-based, parametric CAD program. It has the advantage of having a more traditional CAD interface, but there is a bit of a learning curve; going through the tutorials on the program's website is highly recommended.

* [https://www.freecad.org/ FreeCAD] is a constraint-based, parametric CAD program. Its interface is usually considered more difficult, but recent updates have improved the experience. It is a very powerful software with many built-in tools.
Alternatively, you can download an STL file from an online 3D printing repository like [[https://www.youmagine.com/|YouMagine]] or [https://www.thingiverse.com/ Thingiverse].
 
=== GCode Production ===
We recommend the use of PrusaSlicer (Slic3r) for the Creality CR-10. A settings file optimized for this printer is [https://gist.github.com/MaxBareiss/9f97218f1111aa1ae0247e9d0fbc3083 here]. The most important setting for this printer is to set the maximum acceleration limit to 500 mm/s².

== Webcam Access ==
There are three options to access the webcam to view 3D prints in progress.
* Static View: [http://216.252.200.71:65413/cgi-bin/CGIStream.fcgi?cmd=snapPicture2&usr=Snap&pwd=123snap! Click Here] (This does not work on Hacksburg WiFi, refresh the page for an updated image.
* Basic Stream:
*# Open VLC and navigate to Tools>Preferences.
*# In the bottom left corner of the Preferences window under "Show Settings" click the "All" option.
*# In the search box, type "Image Demuxer" and select the "Image" option.
*# Change the "Duration in Seconds" option to 1.00 seconds and click save.
*# Turn on looping.
*# Select Media>"Open a Network Stream" and type <nowiki>http://216.252.200.71:65413//cgi-bin/CGIStream.fcgi?cmd=snapPicture2&amp;usr=Snap&amp;pwd=123snap!</nowiki> into the Network URL box.
*# Click Play and the video should begin playing at ~1 FPS
*# '''Note:''' This method is a workaround if you do not wish to install the IPCWebComponents.exe required for full camera control. That method provides better video quality and the option to pan/tilt/zoom.
* Full Control: [http://216.252.200.71:65413 Click Here] Visit from Internet Explorer initially to download and install IPCWebComponents.exe. The interface can then be accessed from other browsers (does not appear to work in Firefox).
** User: Operator
** Password: 123snap!
== Planned Printers ==
* Prusa i3 derivative
** Planning discussions started in early January 2015, but stalled.
** '''Current components:''' RAMPS board, Arduino, heated bed, thermistor, user interface board, one pulley with CL2 toothed belt
** '''Missing components:''' Just about everything else
