Hood,
I have a part milling atm, sometimes I get a number in my head but at the moment I can't check it. When I went back after your first post I just looked at the nameing and not the rate, then started the next path up. Kernal Speed has 3 options, my drives use the 45,000 but being in Florida I am subject to frequent power outages. When I do get a power outage the Kernel Speed does reset to the lowest value, can't explain it, I do have to go back in and correct it to the right variable each time this happens. If I dont the behavior in the drives give a less than stellar performance when cutting.
