Python interface coordinates? was created by eslavko

Hello...

Is there a way to read current coordinates (XYZ) within python interface but to include all offsets so the number retrived should be same as in axis DRO.
For now I'm able just to get real coordinates.

Thanks.

p.s.
reading linuxcnc.org/docs/html/common/python-interface.html doesn't show trick for me...

Just take a look at the code of my combiDRO.py, is is located at:

Linuxcnc-dev/lib/python/gladevcp/

It is doing whaf you want.

Seems that this is the answer.

rel_pos = p[self.joint_number] - self.status.g5x_offset[self.joint_number] - self.status.tool_offset[self.joint_number]

I already find that I need to subtract g5x_offset but miss the tool_offset.

Thanks for help.
