I know the real displayed value is set by a touch-off on a lathe.

Why do you care about machine coordinates? So I can set these soft limits with some semblance of knowing what I'm doing. The figures I use should not be diddled by a touch-off, only by the final closure of the home switch of that axis. This then should become the reference from which the limit offsets put in the .ini file are derived. IOW, if this internal var is set to 0.000000 by the final home switch closure, and unaffected by the saved position.txt, then that var's offset at the desired offset becomes what I put in the .ini file. ?? And what motion pin is this reported on? When changing chucks, the Z safe changes, so ideally one should have an .ini for each chuck. But both x safe and z safe are rendered invalid when the toolpost is moved or rotated = waste of time even thinking about that. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
