    All firmware are up to date...

    Using Hypertherm plasma but for this test machine are off. All parts of cnc are grounded and I make special attention in wiring ( shielded...)

    Using Sheetcam ( up to date ) for cam software and GRBL post processor recommanded in other post...

    Error 33 means the Gcode the post created is invalid and thus does not constitute a valid Arc

    Grbl supports valid Arcs yes. OpenBuilds CAM doesn't generate Arcs no, uses interpolated line segments, not as optimised, being a free, basic, entry level CAM (;

    Do you have idea to help me with this ? I can't see what is wrong with my G03 X15.202 Y30.798 I-2.956 J-1.225 ? Decimal ? I change from 0.0000 to 0.000 and no change...
    Do you have website or link for helping me ?

    I have contact Sheetcam admin and wait for return :)

    Thanks for your help and VERY fast reply :)

    Haven't used SheetCAM in years, so I don't have a better post around myself. See Grbl problems - sheetcam.com though, discussion mentions arc errors toward end of page 1 with another Post available on page 2. Getting into editing the post if needed may also be helpful
