Hi, Ed
Did you use g00 moves or Shift + Arrow key to tune your Velocity & Acceleration settings ?
On the Program Run Screen what's your Feed-rate set to ?, Hit the TAB key, What's the Slow-Jog Rate set to ?
If thay aren't set to 100 then your tuming is probably off.
Use Home & Limit's to reverse any axis that run's the wrong way.
A little TLC should fix it.
Hope this Helps, Chip
