Compatibility with Lantek and other high-end software

The ARC_BLEND parameters that you are changing have nothin to do with G2/G3 arcs, they ar for look ahead trajectory planning.

There is a CENTER_ARC_RADIUS_TOLERANCE_MM here:
linuxcnc.org/docs/devel/html/config/ini-...sub:ini:sec:rs274ngc

I tried adjust this earlier with some gcode that you posted but it did not resolve the error.

just tried it. changed to 10 no luck

I converted the file from your earlier post so it would run on an AXIS sim and the same errors happen.
I also ran this file on an online gcode simulator  ncviewer.com/  and it ran fine.
I think that I am unable to help any further. It may be worthwhile posting on the  G&M Codes  section of the forum.

G-code:


Error:

Does by chance Lantec uses absolute coordinates  and not relative on arcs?

Looks like that is it, below is with G90.1 at the beginning of the code:

Hello.
I am still having some errors.
Could you please send your filter? It seems to work without errors.
thank you
