Printing software

Cura for printing

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
