Hi Rich,
Thanks, I am pretty sure that the steps are fine because the machine was working fine before I changed computers, I checked the Y axis and it is not binding, I can turn it all the way to the front and all the way back by hand and it is not sticking nor is X. With the backlash on I am getting a squealing sort of sound with it off I don't, I'll need to recheck the amount backlash.. I tried to cut a circular ring with .2855 ID and .400 OD and it's not perfectly circular the ID is 0.273 and OD 0.418 it looks sort of slanted on the perimeter...? I did recently tram the machine but it was within a couple thou all around so I don't think it's the tram, I've increased the shuttle acc to .05 seems to help with the squealing and a tuned down the steppers but the main thing is that it's not cutting anything to within acceptable tolerance?
