If you are using marlin then I think you have the wrong postprocessor because that gcode is not the proper dialect for marlin. I’d recommend guffy’s postprocessor for fusion.

I dont see that option to select

Those images are too tiny to make out any detail.

Make sure when you select Post Process, you select “Personal Posts” from the Source drop down (the one on the top) and then select the DIYCNC that you installed from the link that Barry posted above in the Post Processor drop down right under it. This drop down remembers your selection, but sometimes forgets it and defaults.
