But the main question is still open: is there any way to tell the backplotter where the centre of rotation is, when the rotary chuck is not at machine Y=0?
In my case the chuck is fixed at Y=700mm. The backplotter always rotates around Y=0 (machine origin), so the wrapped toolpath displays as a large circle far from the actual machine envelope instead of showing correctly near the chuck.
I have already seen the 2013 thread where andypugh said there is no solution.
Is this still the case in 2.9.8, or has anything changed since then?
