I'm having trouble getting a Gecko 320 driver/motor to stabilize. It worked fine before, but after doing some rewiring at the motor, I can't seem to get the vibration adjusted out of it. I have the limit clear up as Gecko recommends and as usual for my setup. I have 90V servo motors.
The only position of the gain and damping pots that give me good performance with no chatter, etc, is with both of them fully counterclockwise. BTW, the Gecko spec doesn't say which direction is full on.
I know that if you tune by ear, you turn the gain up until chatter, then turn damping up until it stops; then turn the gain up, then the damping until you're almost to the end of the damping pot. Doesn't seem to work that way, both pots ccw seems to be the only working position.
I haven't dinked with the other two drivers since I set the system up months ago; scared to at this point.
