Qtplasmac radius to end of arc differs error

Hi All,

Been using sheetcam and Recently changed my OS to Ubuntu from windows. but linuxcnc isn’t happy with the gcode from the post processor. I copied over all the settings from the windows sheetcam to Linux but I get the below error and can’t fathom how to fix it.

Radius to end of arc differs from radius to start.

Any ideas? Thanks

are you using sheetcams linuxcnc-plasmac post processor?

Yes running linuxcnc plasma post processor and I’ve checked arc fitting tolerance and it’s the same as sheet cam on windows that works.

Is the kerf width being compensated in SheetCAM or in QtPlasmaC?
Never on both.
