    Hello all, I'm running blackbox with openbuilds and sheetcam. Parts drawn in autocad. I've been able to get part into gcode and nested and program successfully runs except its not firing torch. I've eliminated any problems with the torch itself and believe it's somthing to do with the post processor, any help is greatly appreciated.

    Make sure your Post is Grbl compatible and sends M3S1000 (if $30=1000) to turn on the relay. (not just M3 without the S word)

    Went through the code and it's reading m3s1000, but now it stops and says invalid gcode tracking tolerance set to .254. Thanks

    Post the file, and screenshot the error (the error shows the line that errored, which helps a lot) but usually that error means your are still not generating Grbl Compatible gcode.

    G64 is not a supported Gcode? (halfway down on gnea/grbl ) You are still not using a Grbl Compatible Post processor.


    You'll need to find a Grbl compatible post, speak to SheetCAM support they may know where to find one.

    If you can do without SheetCAM, OpenBuildsCAM supports Grbl:

    There is 4 different grbl's on the drop down list in my sheetcam and none have worked, I was kinda figuring like you confirmed it was still the post processor. I will hit them up. Thanks again

    Point them at the Grbl Wiki if they argue, it lists the gcodes Grbl accepts. Anything else will error out.

    Oh, something else:
    Looked up G64: G Codes "path/motion blending tolerance" and I think you mentioned
    So may relate to that setting?
