FreeCAD path post processor for laser control.

laser_post

FreeCAD Path post processor for laser control.

This post processor outputs gcode for laser control, it should work
with most gcode lasers.

Defaults:

• Z axis moves are removed
• M5 is added before all rapid moves
• M3 S##### is added before each group of motion controlled moves.

The following command line options have been added:

--laser-off Overrides the default "M5" command for laser off.

--laser-on Overrides the default "M3" command for laser on.

--laser-power Overrides the default "S####" command for laser on. --laser-power "" or --laser-power "NONE" suppresses the power command.

Use "\n" for newlines.

Examples :

  My laser max power setting is 1000 so if spindle speed is set
  at 900 that gives me 90%.
  
  Default output would be:
    M3 S900  for laser on
    M5  for laser off
  
  --laser-on "M4" would produce:
       M4 S900
       
  --laser-power "NONE" --laser-on "M4" would produce:
       M4

  --laser-on "G4 P1\nM3" --laser-power "\nfull power" would produce:
       G4 P1
       M3
       full power

Installation :

• Copy laser_post.py to your macro directory
