Yes. I found this document and follow this instruction.

@dc42 Thanks a lot!
Unfortunately I dont know how to use 74LVC06A chip . Maybe I should change motor witout external stepper driver.
Thanks again!

Hello all
I have problem on duet3 mini5 wifi and nema 23 motor.
I am trying to use Duet mini5 with IHSS57-36-20 Stepper motor which is integrated with stepper driver.

What I know is duet mini 5+ has external stepper drive pin so I connects Pins to IHSS57-36-20 Stepper motor's connector.

Like this
Left red letter is on duet board -> Motor driver connector.

1. V_fused
   2. GND: Step- →PUL-
2. D5-Diag
   4. D5_Step: Step+ → PUL+
   5. D5_DIR: DIR+
   6. +3.3V: Enable+
   7. GND: DIR-
3. V_Fused
4. GND :
5. S_uart_B
6. D6_Diag
7. D6_Step :
8. D6_DIR:
9. 5V_INT
10. GND :
    16. Driver_EN: ENable -

** I tried to use 5V(no.9) instead of 3.3V already.

I set this motor as Drive 5. in configuration In "My duet" Browser. But Motor is not working. here is my configuration.

Motor is making little sounds when it is in idle mode and when I set extruding(I set this motor on E). idle sound change very little. ( I thought i did wiring right way)

Can you give me some advice to make this motor work?
I am thinking it may be because of Steps per mm (in configuration setting). But i am not sure. I spend many days to fix this problem but now I am lost.

** Info

1. Power
   I am using smps 24V output.
2. Motor
   <JMC Original Nema 23 2Nm DC36V>
   24~50VDC
   4.5A 20khz pwm
   Pulse max: 200k

Thanks
