Hey guys, Mach 3 runs great for me with 1 exception. It does this every time. I always need to zero the Z axis a 2nd time. For example, when I touch off the top of my work piece, zero out Z on the DRO, then start the run cycle, Z will go from about 100.000 or so instead of from its relative location from where I touched it off. I repeat the whole process again, touch off, zero out DRO....etc.. and it's fine. Always takes that 2nd time.
Any ideas on why?
