[http://www.yeggi.com/ Yeggi] is a search engine that shows results from several of the sites listed above.

=== Make your own ===
==== 3D Software ====
* [http://www.sketchup.com/ Sketchup] is a free, popular and most importantly, easy to use software which allows for the quick creation of 3D models (requires [http://rhin.crai.archi.fr/rld/plugin_details.php?id=429 su2stl plugin] for STL export/import)
** [ftp://fixme:fixme@ftp.fixme.ch/incoming/SketchUp%202013%20(Mac).dmg Sketchup 2013 Mac]
** [ftp://fixme:fixme@ftp.fixme.ch/incoming/SketchUp%202013%20(Windows).exe Sketchup 2013 Windows]
** [ftp://fixme:fixme@ftp.fixme.ch/incoming/Sketchup%208%20(Wine).zip Sketchup 8 Windows] (This version [http://wiki.winehq.org/Sketchup works with wine])
* [http://openscad.org OpenSCAD] is a script-based 3D editor, which can make use of parameters, conditions, for and while loops, etc... This is currently Petaflot's choice
* [http://www.3dtin.com/ 3DTin] is an online WebGL 3D modeling web-app
* [http://www.netfabb.com/download.php Netfabb] (Linux version)

==== Printing software ====
* https://print.fixme.ch web interface to replace Printrun/Cura (still need Slic3r to create the gcode)
** Currently not connected to the printer and the service is down
** run as unprivlilegied user please sudo su -c /home/francois/OctoPrint/run francois
** Used for the webcam: http://webcam.fixme.ch
* [http://slic3r.org/ Slic3r] and [http://reprap.org/wiki/Printrun Printrun] 
** [https://github.com/daid/Cura Cura]
* To check, http://projectsilkworm.com/
* Check STL files for printability: http://cloud.netfabb.com/
* Buy material in switzerland: [[Resources#3D_Printer]]
* There's a dedicated machine to print: spm.fixme.ch

== Printing ==
=== Software Installation ===
* http://daid.github.com/Cura/
* it's the only software worth it
* Yes, you will need PyOpenGL for it to run. Displaying nice 3d images is not that trivial.

* Recommended: Use the dev version on github: https://github.com/daid/Cura.git (12.10 when I'm writing)
* Required packages: wxPython and PyOpenGL.
* You can use a python virtualenv.

=== First use ===
* On first Cura start, you don't need to upgrade to Marlin firmware because it's already done.
* You should run the checks, at least to check if USB connection between PC and the printer is working. For temperature check, the printer need to cool down (to ~30) before heating and check, it can take looong time.
* Now you can use Cura to print objects.

=== Printing ===
'''Maximum length/width: 180mm'''
* Load a .stl model.
* Change orientation, size, etc...
* Check settings on the left (and in the different tabs)
* Click on the Prepare print button.
* Software will slice the object into GCode. The more you choose a large scale object, the longer the execution time is.
* When it done, click on Print button to open the Printing dialog.
* Wait the software connect with the printer, Connection button will turn from clickable to readonly and Print button will turn from readonly to clickable.
* Set the temperature with the arrows (yeah it's not working by putting the number directly)
* Wait a bit so the hot end is distributively warmed
* Extrude before printing, so the wire is at the start of the hot end
* Make sure the wire is extruding correctly (the output wire is regular)
* Click the Print button.

==== Settings ====
* Walls: 0.4 (1 wall) is good
* Print speed: 80mm/s is clean (you may increase temperature for more speed)
* Infill:
** strong material, 80-100%
** Light print, 10-15%
* Temparatures: ~230-240°
* Support type:
** Exterior when there's a big overhang (we made a 10cm overhang without support, but generally it's >1cm)
** None in general
* Raft: needed when there are small pieces at the bottom (so they stick to the bed)
* Experiment !

=== Important points ===
* '''[http://62.220.135.248:8081/stream.mjpg KEEP YOUR EYES] ON THE PRINTER THROUGHOUT THE PRINTING PROCESS!!!''' And clean what could interfere with the printing.
* BE carefull with the end stops, [http://www.youtube.com/watch_popup?feature=player_embedded&v=IYXnxllWcyc if they don't work], turn OFF the printer immediatly and fix them (by bending the metal part a little bit for instance)

=== After printing ===
* If a pile of plastic has formed in the extruder, remove the wire complitely and cut it
* Put the leftover in the box, maybe one day we'll be able to [http://www.filabot.com/ recycle it!]

== Finance ==
* To buy new PLA filament and upgrade parts, there's a piggy bank next to the printer
* The cost in filament is indicated by Cura, just take a guess to add general maintenance cost of the printer
[[File:piggy.png|300px]]

== Files ==
You can find 3D models to print from [[#Find model online|this list of websites]]. There is also a folder full of previously printed STL's on the machine attached to the Ultimaker.

* FIXME keychain: [[File:fixme-key.stl]]
* Tablet support: [[File:tablet-support.stl]]
* Pincette: [[File:pincette-led.stl]] [[File:pincette-piles.stl]]

== Webcam ==
* An AXIS webcam is deployed on the printer and accessible by IP: http://62.220.135.212
* There's a service for viewing the webcam
** https://webcam.fixme.ch
** Repo is in github: https://github.com/fixme-lausanne/fixme-webcam
** [[Gitolite#Deploy|Auto-deploy]] by pushing on the <code>live</code> branch in <code>ssh://gitolite@git.fixme.ch:1337/fixme-webcam</code>

== Maintenance ==
==== Issues to fix ====
* End stops are getting crapy
* Belt tension is bad
* Y alignement problems
* Fan can't be turned off (electrical problem?)
* <s>http://wiki.ultimaker.com/Jamming</s>
* <s>Needs a new tube and fixation</s>
* <s>One of the nozzle is loose. When the extrusion begins, the pipe move</s>
