Problems with homing the x-axis

heinrich.platau

Hello everyone

I have a problem with my printer / duet board.

Suddenly (after 1,5 years working perfectly) it is not possible to home the x-axis.

If I send the command, the printer head is moving just a small distance right and left (along the x-axis) from its position. The distance is about 1 or 2 cm. Also there is a strange noise.

During that failed homing process, the duet shows the following message:

G28 X
Warning: motor phase B may be disconnected reported by driver(s) 0

I have checked the stepper motor for a mecahnical failure. But the stepper seems to be ok.

Can you help me and give me some advice? How can I check wether the On-Board Driver on the Duet Board is defective?

I use a DuetBoard 2 (Ethernet) with firmware version 3.2.1

Please tell me, if i should post any further information

Thanks a lot for you help

@heinrich-platau fully check the wiring for your motor.
use a multimeter so you can verify each of the coils

You are right!! Problem solved!

I thought about the worst case but I'd better check the most obvious error.

Thanks.
