Error offset in preview

hi, gmoccapy generates me an offset with respect to axis. what can it depend on?

Do you have an x or y offset on your tool?

no, I just replaced in the [display] gmoccapy section with the axis configuration where there is no error.
the error is also on z

I do understand you mean the preview.
That is because of rounding calculation the preview caused by gremlin.

I do know that, but gremlin is a real complicate part of software.

Thanks Norbert, but the error is only in the preview?

I did a trial run and the error in x and y is not there. While in Z yes, the tool is lowered with respect to the origin. I recently applied automatic tool measurement and I probably made some mistakes. I didn't understand this well:

Thanks for everything

Any gcode that moves the offset could do this. Linuxcnc doesn't explicitly tell the gui to redraw the screen if an offset moves.
