General Mach Discussion / Debugging Servo Motor Setup
« on: September 29, 2006, 03:34:54 AM »
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 ?
