Hello everyone ¡ ¡
I am starting in using a geckodrive G320X to run servo motors from an old HP plotter
7475A , As I can see, the encoder of this motor is a cuadrature one with 500 steps
so geckodrive counts 2000 steps per revolution. I use a pic 12f683 to send pulses
and change direction of rotation.
The thing is, the lowest speed the more error I have so I try diferent speeds.
I can see better performance at medium to high speed but any way I lost position
if I leave the motor running for a long time.
Y put two marks, one in rotor and one in motor to see if motor shaft returns to this marks after few turns forwarding and reversing the motor.
I have tried differents ways, adding a small delay after change direction of rotation, decreasing speeed before reach the mark , but same thing, l lose position.
I hope someone can help me if I am doing things wrong
Regards
