This python script has the only purpose of get rid of some Gcode I find useless:
- Comments. I use Candle as my GUI for controlling my CNC machine which has grbl in it. Grbl doesn't play nice with comments in the code and Candle stops the execution of everything when grbl throws an error. This is aweful.
- Homing when finishing Etching I would like the machine go Home (G0 X0 Y0) when it finishes etching.
- Only one Tool Size for drilling I found the pcb-gcode hard to config when I only have one Tool size for drills. I prefer to post process the drill file to delete all the code placed for Tool change since I have only one size of drill.
- Just place this python file in the same directory where your files were generated by pcb-gcode (the .etch.tap and .drill-tap files).
- Run with
python pcb-gcode-postprocessor.py - Wait for the program to finish (should not take more than a second or two)
- You are ready to etch and drill those PCB's
