      Hi!

      My cousin bough a used CNC which is running with a Duet2 board.

      As he knows Blender very well, he would like to use Blender CAM, which does not output GCode for RRF. Which machine should he use, from this list:

      • Iso
      • Mach3
      • LinuxCNC
      • Fadal
      • Heidenhain (530, TNC151)
      • Sieg KX1
      • Hafco HM-50
      • Centroid M40
      • Anilam Crusader M
      • Gravos
      • WinPC-NC
      • ShopBot MTC
      • Lynx Otter o

      Is GRBL ok?

      Thanks.

      Frédéric

        Mmm, Blender CAM generates strange G-Code:

        G0X0Y0Z10
        X3.477Y3.144
        G1Z0F500
        G0Z10
        X3.666Y3.004
        G1Z0
        G0Z10
        X3.868Y2.883
        G1Z0
        G0Z10
        X4.081Y2.782
        G1Z0
        G0Z10
        X4.303Y2.703
        G1Z0
        G0Z10
        X4.531Y2.646
        G1Z0
        G0Z10
        X4.764Y2.611
        G1Z0
        G0Z10
        X4.999Y2.599
        G1Z0
        G0Z10
        X5.235Y2.611
        

        For lines only containing X/Y coords, G-Code simulators use the previous command (G0, here), but RRF does not seem to understand such lines... Do you confirm?

          @fma for that, RRF needs to be in CNC mode. See M453: https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m453-select-cnc-device-mode

          In CNC mode, it is valid in a Gcode file to send G0 or G1 on one line, and then just send co-ordinates on the following lines.

          It appears to have been supported since RRF 1.x/2.x. Check what version is on the Duet with M115.

            @droftarts Thanks. I'll ask my cousin to check.
            In the meantime, he tested the ISO prostprocessor, which seems to work fine.
