Fusion 360 codes no longer work in GC

Welcome to the Forum!

How many lines does the gcode have?

Edit: If i was using f360 and had that error, i would try to limit precision to 0.1mm (enough for the Maslow) hoping that that will reduce the amount of lines.

Did you use the Maslow post-processor?

Here i found the general drawing precision, but there might be another setting for gcode.
