Leadshine DM556 driver not working with expansion breakout board

peter

Hi,

the DM556 driver always shows a constant red led once i try to move the stepper. Stepper is not moving

SetuP:
Duet2 V1.04
Expansion Breakout Board V1.2
Firmware 2.0(RTOS) (2018-06-05b3)

Config:
M569 P5 S1 R0 T5:5:5:0 ; Drive 9 goes Forwards (i also tried without R and with T2.2, T4)
M584 Z5 ; Power Z with drivers 5

Wiring:
I tried to connect all DM556 pins directly to the breakout board. Also tried to connect E+, D+ and S+ to 5V. Connected 2 DM556 and different steppers. Stepper is receiving commands but shows of constant red led once i trie to move motors.

Any idea?

I don't know about the DM556, but on some external stepper drivers the EN+/EN- are actually a disable input, not an enable input. So try with those wires disconnected, or change R0 to R1 in the M569 command.

Does the manual say what the constant red LED means?

@dc42 your are a genious! Thats it. Thank you.

For Leadshine DM556 driver do not connect Enable+ and Enable- as this disables the driver.

You can connect the other leads directly to the breakout board driver connector.

Config:
M569 P5 S1 R0 T5:5:5:0 ; Drive 9 goes Forwards
M584 Z5 ; Power Z with drivers 5

Also check for driver number if the motors are not spinning:
