    Hi, I've recently acquired a Workbee CNC and have been playing around with PCB milling. i have been using CamBam to do up the tool paths (there is probably a better way of doing PCB tool paths but i want to learn the ins and outs of CamBam first) and when I use canned cycle drilling for small through-holes with 0.8mm drill bit the Workbee gives an error that G81 is not supported. Any help in the right direction to drill straight non spiral cut holes with the Workbee Duet controller and CamBam would be much appreciated.

    The Duet uses Rep-Rap variety of g-code (similar to, but not identical to grbl) - the g-code supported by the Duet is in the link below.

    Thanks Peter, I appreciate the point in the right direction. Still learning and working hard to get comfortable running my machine, hopefully one day I'll be as comfortable with it as I am with my printers... It is a steeper learning curve, I must have a better look into GRBL and more importantly save some headache and use FlatCAM.

    As I said above @Cian Warren, the Duet does not use grbl - it uses Rep-Rap variety of g-code which has some significant differences. There are also some differences in the way the machine behaves.

    Thanks Alex, my apologies I somehow missed your previous reply Ill be sure to check out what Rep-Rap G-Code is supported I'm familiar enough with it from the couple of printers I've built which makes life a bit easier. Again thanks for this info.
