Hello everybody I'm writing because i have a problem setting backlash on my systems. I've tried on mach 3 and 4 to set backlash, with no success, the software totally ignore my setting and acts as if no backlash was specified. I had same problem with mach3 now for my computer setting i would migrate on the most recent mach4. I have a demo version for now and this problem stop me to buy licence. I use pokeys 57 to run my step. I have looked in forum but i can't find any topic with the same problem.
