Some experiments where made with simavr to prove the independence of the xy and uv planes. For the simulation the gcode of the inner panel of a 2 panel Supergee II 2 wing was used. Simulation was performed with 2 runs for the right and the left wing.
The original grbl-0.8 takes into accout the maximum speed (feedrate) and the acceleration of the tools path. Adjustments to planner.c where made to consider the change from a single tool path (i.e. nozzle of 3d printer) in 3 dimensions to two semi-independent tool paths in 2 dimensions (wire end of hot wire foam cutter).
Here are the VCD-waveforms from the simulation:
- Real live tests have to be made.
