Will Lightburn work with Mach 3 controlled CNC machines with a laser?

Output Gcode for use on Mach3

When I search “Mach3” on the forum, a number of topics already discuss compatibility:

Some additional digging provides these posts as well.

Output Gcode for use on Mach3

If you’re using Mach3 without an external controller, the spindle PWM doesn’t respond fast enough for laser work. If you’re just doing “on/off” it might be ok.

How to use lightburn with mach3 and gecko g540

LightBurn will not drive the machine directly, but you could probably use it to save GCode that you could run on Mach3. I’ve been told that Mach3 is not usable for image engraving because the PWM output for the spindle doesn’t change fast enough, but it might be ok for engraving. If you create a GRBL-M3 profile in LightBurn and use the ‘Save GCode’ button in LightBurn you can probably run that GCode on Mach3.
