    Hello,
    I'm coming from a 3d printing background, and I'm familiar with working from .stl files. I've got my Plate maker assembled and working, and would love to use some of my .stl's as a basis for my machine work. I have installed MESHCAM, it seems like a great way to reuse my .stls.

    I can load my saved files from Meshcam into Openbuilds Control just fine. But when i attempt to run them Open Control gives me this message: Error: 20 - Unsupported or invalid g-code command found in block. [M6 T1]

    It gives me the same message no matter what post-processor i select in MESHCAM.
    My set up:
    Plate cutter C-beam running Grbl 1.1g on the controller.
    CAD: Fusion 360 to produce .stls i can 3d print, (or hopefully) machine.
    Open Control 1.0.183 on my pc
    Thanks so very much!

    Chris

    I was able to do STL files in Estlcam.. there is a YouTube video
    Takes a bit if fiddling for sure. I was using Tinkercad for the drawing and Estlcam to make the code.
    Cheers

    Grbl does not support Toolchange commands. CONTROL just shows what Grbl says

    Investigate Post Processors. Cam software usually has a profile/post specific to machines (they dont all speak the same subset of gcode) so make sure you export in a Grbl friendly post

    Or manually edit gcode and remove unsupported entities like tool change commands

    Hi @Chris Hauser, have you tried using Fusion 360's cam functions to generate G-code from stl files? This link is to a suitable post processor.

    Fusion 360: grbl post processor install (the easy way)

    Alex.
