I am adding a 4th axis to my Mach 3 driven CNC. I need to swing 45 degrees from 0 each direction and can, by using a lever switch, use one limit for Home, --A and ++A . The question is, Can I eliminate having adjustable stops at each end by using the Home 0ffsets entries in the Motor Home/Soft limits dialog?
When you home the machine, instead of adjusting the limit switch stop positions to get the machine to find the correct zero, could you home the machine(--A), measure the position error and reset the Home Offsets to compensate? ++A would be for soft limits and could float a small amount.
Otherwise, If I say 0 is 45 degrees away from home why could I not say Its 44.8 degrees or 45.3 degrees? Thanks Ed Courter
