Makerspace 3D and 2D

Leo's notes about 2D and 3D design and tools.

2D - Laser Cutting and engraving

Life cycle:

1. Design the 2D object (Inkscape, or any graphical editor)
2. Export to a compatible format: Gcode or DXF
3. Send to the laser cutter

Inkscape for Laser cutting

Good and short tutorial videos:

• Laser Cutting With Inkscape Tutorial

Notes: about Inkscape and Linux

• There is an extension for Gcode export.
• It appears to be written for Python 2, while the newest Inkscape appears to be running Python 3. There might be problems with running the extensions. Change the default version for python to be 2.7 like this:
  • Open Inkscape preferences, usually here: ~/.config/inkscape/preferences.xml
  • Search for

<group
    id="extensions"
    …
    org.ekips.filter.gears.pitch="20"
    org.ekips.filter.gears.angle="20" />

• • Change to - add the following:

<group
    id="extensions"
    python-interpreter="/usr/bin/python2.7"
    …
    org.ekips.filter.gears.pitch="20"
    org.ekips.filter.gears.angle="20" />
