Is your feature request related to a problem? Please describe.
I have been using Fabex to operate a laser on a machine with Klipper firmware. Klipper solidified PWM tool control in late 2023. I am able to use the Gravos post processor pretty successfully, but there are several things that would be greatly improved with a dedicated post processor.

Describe the solution you'd like
A clear and concise description of what you want to happen.

A Klipper post processor would be the ideal outcome. It would have the following features:

  • It would use the Gravos post processor as a starting point
  • Klipper uses G4 instead of G04
  • Klipper doesn't store differences between G0 and G1 feed rates. These feed rates need to be explicitly stated any time either of them vary from the previous G0 or G1 command.
  • Klipper processes .gcode files, not .nc files
  • comments in Klipper gcode are lines that start with ;

Describe alternatives you've considered
I have been touching up the generated gcode by hand.
