An addon to simulate a CNC inside blender. The idea is to read .gcode and either lay out the toolpath as a polyline or move an empty to points along the path using a modal. Combined with dynamic paint you can simulate milling etc straight in Blender.
Below is the toolpath for milling one side of a wooden button for a dress. There are still some intermittent issues with the XZ and ZY plane arc angles. Will be resolved shortly
The gcode parser is forked from Peter Rogers (https://github.com/parogers/gsim) and adapted for 3 axis coordinates and support of multiple planes.
