Mach3 Laser Post Processor

[ian.tyssen]

Hi there, I'm very new to CAD and CAM in general, and have been messing around with Fusion's CAD side of things while I get my 5x10 CNC mill/laser set up (BuildYourCNC GreenBull 5x combo, driven by a PoKeys57CNC board).

I've run some gcode successfully for milling. I'm trying now to get the laser going, but am having difficulties at the post processing stage and onward. I've looked through the forums, and some threads seem to apply to a point, but I have what seems a somewhat unique combination of equipment and software. My laser on/off is currently set up to be controlled by Coolant Mist On/Off (M7/M9), but I've also created a new Mach3 profile in which it's controlled by Spindle On/Off (M3/M5).

I have a simple model (our company logo from SVG, extruded to 0.1"), and have created a CAM setup using Cutting > 2D Profile. All of that seems fine. Once I get to Post Processing, I can't seem to figure out what processor to use. The general Mach3Mill processor doesn't work (verified by other posters in the forum). I've also tried the Mach3Waterjet post processor from AutoDesk, but that fails - doesn't even open in Brackets, just a file with appended .fail extension (it's blank when I open it afterward). I've also tried other laser post processors but they make my machine do odd things, as I was expecting.

It seems the solution would be a custom Mach3Laser post processor, but I certainly don't have the know-how to do that myself. If anyone knows where one would go to have that done, or has a solid workaround that doesn't require major manual gcode edits every time, that would be very helpful. Thanks!
