The steps for lincurve.0.x-val-## are at 2.25" intervals from about .050 away from the nut of an ER40 adapter in the spindle, carrying about 22" of slightly crooked A2 rod for the measurements. However it may be that that the lincurve stuff is too early, but I'm not seeing its output change. So I think I'll disconnect the offset outputs and temporarily restore straight thru, then see what happens to offset.0.out when it has no control. Probably tomorrow as I got up to putz with this about 5Am local. > Halscope might help. Maybe, if I can get it to move at all. Z is ok, but X is frozen due to the F.E. :( Thanks Andy. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
