Richards, I have a IH mill that is full cnc. Mach will allow you to counteract for any backlash and set a couple of parameters so it will be fluid. I tried both manual/incremental and MDI and very quickly found that MDI moves of .1 or 1 inch were able to show the backlash comp much better than manual. As for accuracy before i was done with all the set-up, i just had to make some chips and cut a 1.5" circle and measured it to within .oo1" of being round. with some runin and squeeking it in it'll improve. Right now i'm trying to get the vfd on line and it be giving me fits ! I'm tired now ... good nite all ....
