Python utilities to communicate with the Shapeoko desktop CNC machine and its GRBL controller.

shapeoko commandline utilities. run with --help option for more info.

• gcat: send a gcode file to the grbl controller
• gdraw: use keypresses to interactively move the shapeoko tool.
• gsh: send gcode commands to the grbl controller
• gjoycat: jog the spindle using a joypad to set zero; then send a file (requires pygame)

• grblstuff.py: library for chatting with the grbl.
• getch.py: get a keypress
• GCodeAnalyzer.py: analyze gcode to get time, length, bounding box and stuff
• JoyStatus.py: manages the joypad

Various utilities to manage gcode

• gcode3dZopt.py: optimizes heekscad 3D gcode by avoiding to follow the 3D profile of the model, and replacing it with G0 moves
• gcodeAnalyze.py: executable wrapper for GCodeAnalyzer, returning bounding box and time
• gcodeconv.py: convert grbl-style gcode (without redundant G1/G0) produced by heekscad into more verbose and general gcode
• gcodeopt.py: inspired by gcodemillopt, optimizes MakerCam gcode by minimizing G0 moves
• gcodeupdownopt.py: removes useless up/down moves
• truncate.py: truncates MakerCam gcode. Modified from https://github.com/jhessig/metric-gcode-truncator

sample gcode files (give these to gcat), including the shapeoko hello world.
