Hi Bruce,
If its any help this is what I have done in bCNC for laser work:
I have added 4 user defined buttons on the control tab:-
????????????Laser mode on; ? ? ? ? ? ? ? ? ? ? ? ? ??$32=1
? ? ? ? ? ? Laser mode off; ? ? ? ? ? ? ? ? ? ? ? ? ??$32=0
Laser constant power mode;?????? M3 (Laser only switches on during G1, G2, G3 off during G0)
Laser dynamic power mode;?????? M4 (Laser power varies with feed rate automatically)
I set the Z to zero when generating the G-Code.? Then before I start the job, I just press the laser mode on button followed by the laser mode I want to use.? The software takes it from there.? Don¡¯t forget to select laser mode off when you¡¯re finished as it is stored in the Arduino and will still be active the next time you use it.?
Happy lazing,
Marcus
