Closed loop stepper motors on duet2
Posted: Thu Oct 24, 2024 2:36 am
Hello, I occasionally read on the forum. Now I have a question and Ryan from Ooznest told me to place it here.
Because he had no experience with closed loop stepper motor.
I try to connect closed loop stepper motors to a duet2 with an expansion breakout board. Before I had normal stepper motors with external drivers on the duet.
When I use the jog commands (G0) with the buttons it works. When I use a other command,like homing (G1), it goes wrong. Stuttering movements and the distance is no longer correct. The distance is ok when i use the buttons.
If i set the closed loop running off with a switch, same result.
The strange thing is that the driver does not give an alarm for the missed steps. So the driver does not see the missed steps.
When I block the motor, the driver go in alarm because of missed steps.
Does anybody have experience with this? Or an idea how to solve this?
