I managed to make a py script that converts the code. I print the M190 PXXX with the material number i want, and it runs as a separate program.
of course, the program just adds the right offsets for the kerfs, and replaces the "G" moves and adds the kerf based on hal parameter. All good.
The problem is the G03 moves. Lantek exports this arcs with some error in the arcs and i get: radius to end of arc differs from radius to start linuxcnc
What could be the problem?
Here is a sample of ALMOST zero problems: (The error i get is always the same)

Is there any way to merge the arcs or add a line before/after that will enable me to remove this difference?
I tried to mess with some INI parameters such as:
ARC_BLEND_ENABLE = 1
ARC_BLEND_FALLBACK_ENABLE = 0
ARC_BLEND_OPTIMIZATION_DEPTH = 50
ARC_BLEND_GAP_CYCLES = 4
ARC_BLEND_RAMP_FREQ = 100
is this the right approach? I had zero success (always the same errors)
Isn't there a way to allow more %relative error and just merge the lines?
