Tolerance issue affecting lathe roughing

[Dylan Gondyke]

Just installed 2023. Can't swing an arc on a mill. Cimco doesn't like it either. What the hexk changed?

My first guess would be that in the version change, you somehow got a change in config system tolerances, or control def tolerances. This could be that userfiles/MD/CD didn't get migrated that you needed and you're working with new default values, or that they didn't migrate properly.

[gcode]

Are you sure Cimco isn't pulling a a lathe template for your backplot??

Customer is getting the same problem with 2023.
gotta be something simple.

Machine craps the bed on line 34. Haven't analyzed the circle's code since the problem is obviously in MC.
