Invalid GCode Error 33

Trying to simply carve some letters onto wood. It starts carving the B perfectly but then gives me an GRBL error in the middle. Could it be the font I’m using?. (64.0 KB)

It seems to fail at line 819. Is it related to the J0. It seems to be the first time this command with value 0 shows up. There are other J values but not 0.


Thank you so much @RichCournoyer. Exporting the file out of Fusion360 in mm worked perfectly. Much appreciated.

I had this happen numerous times with various Fusion 360 files. It typically happened during an 3D adaptive clearing step. These were all in inches so I also started using metric units and haven’t had the problem since.
