Firmware Supported Raster Performance CNC Support Pull Requests Accepted
Grbl > v1.1f (ATmega328) Yes Good Great Yes - improvements
Grbl-Mega (ATmega2560) Yes Good Great Yes - improvements
Grbl-LPC (LPC176x) Yes Great Great Yes - improvements
Grbl_ESP32 (ESP32) Yes Great Great Yes - improvements

Repetier Yes Unknown No Yes - improvements
RepRapFirmware Yes Unknown Yes Yes - improvements
  • If fast raster engraving is important for you, we recommend replacing Smoothieware with grbl-LPC ( which also runs on the LPC1769 based boards and performs much faster for laser raster applications.


If you want to contribute, below are long standing community-requested enhancements, that a) we don't have time to code or b) need extra skills

  • GCODE Optimiser - to cut down on G0 moves (something like
  • Implement "Raster > TSP-Vector" operation
  • More Controllers! Help us implement more firmwares (improve TinyG add Marlin/Repetier, etc)
  • WebGL Transformation Filters to use Webcam to setup stock
  • Automate Electron Builds for all platforms
