3d printer

Information

 * http://wiki.ultimaker.com/Newcomer_guide_to_your_first_3D_print
 * 3D Software:
 * OpenSCAD is a script-based 3D editor. it can make use of parameters, conditions, for and while loops, etc... This is currently Petaflot's choice
 * http://www.3dtin.com/ Online in the browser
 * http://www.netfabb.com/download.php (Linux version)
 * Sketchup (old version works with wine) with su2stl plugin
 * 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
 * Used for the webcam: http://62.220.135.248:8081/stream.mjpg
 * Slic3r and Printrun
 * Cura
 * To check, http://projectsilkworm.com/
 * Check STL files for printability: http://cloud.netfabb.com/
 * Buy material in switzerland: Resources

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

 * 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

 * KEEP YOUR EYES ON THE PRINTER THROUGHOUT THE PRINTING PROCESS!!! And clean what could interfere with the printing.
 * BE carefull with the end stops, 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 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

Issues to fix

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

 * Thermocoupler and the heater are stuck in the head
