Fusion GBRL Invalid Commands

Hi All, I bought a 4030 v2 Pro a few months ago and only now have it working properly. Software Issue, not hardware.

The Question is, is there a simpler way to get GRBL from Fusion CAM without the invalid commands? Read to end…

Short story long…
I have been 3D designing and printing for about 5 years and thought I would take a go at CNC. I have used Fusion for years and was stoked to find out I could use it to create the CAM files for my new CNC.

I followed some tutorials on how to create a GRBL file, but every time I tried it on my CNC it would just stop and throw up an alarm. Tried all sorts of ways to zero everything in, no joy.

Thought, what if I take the STL, put it into different software to output the GRBL…Boom, it worked. I used ESTL CAM to create a file, all was good in the universe. But I didnt have the control of the CNC that I had in Fusion with STL files.

So, I opened a Fusion GRBL (.nc) file in ESTL CAM - the app to run an Arduino based CNC, and it showed all the GRBL commands, but with errors, ‘Invalid command “G94”’.
I used Visual Studio Code, to open the file and, to remove the invalid commands, saved the file and it all works as required.

So the Question is, is there a simpler way to get GRBL from Fusion CAM without the invalid commands?

I don’t use Fusion CAM, but… grbl interprets a restricted subset of gcode in order to fit on small microcontrollers.

It’s typical with gcode to need a “post” (postprocessor) to match the gocde processor. Autodesk suggest this post Post Library for Autodesk Fusion | Autodesk Fusion for grbl
