I try to connect a closed loop stepper motor to Duet2 using an expansion breakout board. Before I used a normal stepper motor with an external driver on Duet.
When I use the jog command (G0) with a button, it works. When I use other commands like homing (G1), it goes wrong. The movements are not coherent and the distance is no longer correct. When I use the button, the distance is ok.
If I set the closed loop operation with a switch, the result is the same.
The strange thing is that the driver does not alarm for missed steps. So the driver does not see the missed steps.
When I block the motor, the driver alarms for missed steps.

Does anyone have experience with this? Or know how to solve this problem?
