  • If you have a Smoothieware based controller, but performance on Raster is choking you with stuttering moves: This is a known issue. We recommend switching to which runs on the LPC1769 based boards for now, as this performs much faster for laser applications. Want to help fix the Smoothieware stuttering issue: Contact @openhardwarecoza and I'll give you details on the testing regiment we need to provide to the Smoothieware team to prove the point


If you want to contribute, the 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
  • More Controllers! Help us implement more firmwares (improve Tiny, add Marlin/Repetier, etc)
