General Mach Discussion / Re: Debugging Servo Motor Setup
« on: October 02, 2006, 01:10:56 PM »
Thank you for the help guys. I think I have determined that the problem is intermittent and only tied in with Jog. When I directly command the movements, I dont get any noise. But when I'm just jogging, I do. I have played around with different units on the jog, but it still seems to be random in when it clunks at me. Whats even stranger is I can watch the motor pullies and when it clunks there is no visible change in pully speed or belt speed.

Chip,
Thanks for the ideas. Unfortunately the problem still persists. I was reading that optoisolated board have longer then usual signal delay issues. I'm wondering if my problem is I can't increase the step/dir pulse delay enough?

I am running servo dynamics amplifiers and motors. They are being driven by pixie p100s. The pixie is being driven by a bob campbell combo break out board.

I have tuned the motors in accordance with the instructions in the pixie manual, using Pixie's graphical tuning software and direct serial connection to the pixies. The motion is smooth and fast. No jerking, no vibrations.

However, setting up the motors in mach 3 is giving me different results. The motion is jerky, loud and vibrates. Seeminlgy- regardless of speed, the motors jerk and vibrate the whole mill.

I've played with step/dir delay times, decreased the velocity / accel. Kept the accel down and just increased the velocity. Nothing seems to keep them from jerking around.

Very confused. What am I missing ?
