Things to make
This script has been tested to created a 50mm cube from 7.5mm clear acrylic, here are the settings used.
Interestingly, the cube had an internal width of 42mm and external width of 57mm - this was due to the DPI, the generator assumes 100 DPI, the Inkscape default is 90 DPI. Once set correctly, it is highly accurate.
|Cut Width (Kerf)||0.1|
This is a Perl script...
This is untested. May work well with wood but will not play nicely with the 7.5mm acrylic. burn baby burn the fun part
Help / issues
It's been found that if you try cutting with Acrylic underside's protective film removed, you will find 'swirl marks' after cutting. These are caused by the heat/smoke being extracted from the cut. To fix this, simply leave the protective film in place until you are finished cutting.
NOTE: The demo software will crash in the demo on A0 "Blacknose" settings. Please change the file "syscfg - Blacknose.ini", find "NeedRevise=1" under section "[TWOAXIS_0]" and change it to "NeedRevise=0" - a revised download may be provided soon. Source - Nottingham Hackspace wiki
