backlash and feedhold questions
« on: March 22, 2018, 10:56:46 AM »
I have a Tormach 440 up and running with a usb smoothstepper. I have two problems that i have not sorted out yet. I have  backlash enabled and proper numbers in there (.0012" in z). When taking a cut across x axis, the cut starts and about mid way thru the cut the z moves .0012" and then finishes the x cut back at z0.  If i disable backlash, it does not do this. The machine is set up to home off of switches. The second problem i have is that feedhold is about useless. It was never that great with parallel ports but with the SS, it goes even longer before finally stopping. Is this normal?
