New to CNC with duet3d



  • Hi.
    I am new to the CNC side of things, i am bale to create models in fusion 360 and have watched some tutorials about creating tool paths and the manufacture side, however i always get errors from the duet control page. I am using a Buffalo CNC 750mmx750mm and trying to create a basic cut initially.
    im getting this error currently.

    24/07/2020, 17:55:40 Error: Bad command: S5000 M3
    Warning: M8 command is not supported
    Cancelled printing file 0:/gcodes/1001.nc, print time was 0h 0m
    Error: G0/G1: target position outside machine limits
    24/07/2020, 17:55:37 M32 "0:/gcodes/1001.nc"
    File 0:/gcodes/1001.nc selected for printing
    Warning: G94 command is not supported
    24/07/2020, 17:55:37 Upload of 1001.nc successful after 5s
    24/07/2020, 17:55:18 Connected to 192.168.0.34

    is anyone able to help please? or point me in the direction of a tutorial that will help?

    thank you 🙂



  • Which Post Processor are you using?

    The purpose of the Post Processor is to convert Fusion's native toolpaths, into gcode which your machine can understand. Since Duet is more meant for 3D printing, and does not support all cnc related codes, you should use a Duet compatible version of a Post Processor - this ensures the right commands and parameters are in the output (and nothing which will cause "Bad command" errors).



  • Hey, exactly what @Jacotheron said. Here are a couple of post processors found on the forum, but you can search for others too. You'll have to try some out and see what works best for you. If you find one that works, you may also need to manually edit the Gcode to add or remove commands as needed (I have to do this).

    I've used this with success:

    I tried this but it didn't quite work for me:

    Search google for how to import a post-processor into Fusion360



  • @Jacotheron ah thank you 🙂



  • @jpomo10 Brilliant thanks, I'll try that 🙂
