Hello,
I am new to this site so forgive me if I do not understand everything. I have an old Knee vertical cnc Lagun mill that I install emc 2.4.6 with John's Pico Systems digital to analog. I have old west amp servo drives which I believe are called velocity drives due to they speed up with dc voltage increase. The system, after Johns great help is working great except for the it does not seem to be balanced. With Pico system shut off I have the driver cards balanced to zero and motors hold with no movement. When enabled with emc there is a .008 motion to the right and then back again. I have used hal scope to tune the servo loop to .005 error. Can run the system 200 inches per minute with out error. But the back and forth movement while that axis is not moving cause a wave pattern. It does the same amount on x and Y. I am not sure what the hal values stand for to stop this. Please advise and please be specific since I am new to this.
