Radios to end of arc differs

I have the same problem ...

i have the only options, the width of the nozzle is 0.8 mm 

Well, if someone had the same error, please check the final part where the nozzle inlet and outlet is configured, I had it configured in an arc shape and it is where the problems that I had with different arcs were presented, now I use straight inlets at 90 degrees for exterior profiles and I no longer have those problems, everything works fine !!!

There is a gcode setting to select absolute or relative coordinates for arcs. I wonder if Fusion has it wrong?

If you look at the posted gcode that doesn't seem to be the issue.

Actually now I want to cut a letter for a sign and I have that same radius problem, I change tolerance, torch diameter in Fusion and I don't know what else to do to fix that problem.

Have you tried using Inkscape ?

I generated the same file in sheetcam and it works very well, but with fusion 360 I have that error, now I'm going to with inkscape but ideally everything works in Fusion

Inkscape already has the post processor for Plasmac or do I have to download it from somewhere?
