General Mach Discussion / Re: New startup

All:
Just a follow up to the group that responded so excellently to my inquiries to thank you. I replaced the laptop with a desktop PC that was lying around at work. They couldn't use it because they forgot the admin password and could not log on, so they gave it to me. It is a VERY good box with lots of speed & RAM. I loaded MACH3 on it and did the tuning thing. It came along well and is running great. The motors get hot, but I have read they run up to 100 deg C.
One thing does confuse me is the pulse per unit setting in the motor tuning page. It asks the number of pulses per unit(inch). The motor has 200 pulses per rev driving a 5 pitch ball screw, so it should be 1000 pulses per unit(200 pulses X 5 turns per inch or 1000). The motors won't run at that setting, but they do run at 10000(10K). What gives? Am I missing something? Also, I can change the acceleration rate now to quiet the motors a little. Anything over 8 seems to really make the motors & machine howl. 6 seems to be the smoothest.
So with all that said, the machine is up and running and I can make parts. My next project is to mount limit switches. Any helpful hints are appreciated...
Thanks again:
Joe
