I'm trying to connect a closed-loop stepper motor to a Duet 2 controller using an expansion board. Previously, I used a regular stepper motor with an external driver on the Duet.

When I use the button to execute the jog (G0) command, the motor works fine. However, when I use other commands, such as homing (G1), the motor's movement becomes choppy and the distance is no longer accurate.

The same result occurs if I trigger the closed loop using a switch.

Strangely, the driver doesn't issue a missed step alarm. Therefore, it cannot detect missed steps. However,

when I lock the motor, the driver alarms for missed steps.

Motor and expansion board: [https://www.oyosteper.com/goods-587-1-axis-closed-looop-setper-cnc-kit-Series-12-NM-NEMA-23-Motor-Driver html]. Has anyone encountered this situation? Or is there any solution?
