Duet 3 mini5+ with IHSS57-36-20

eznish

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.

2. GND: Step- →PUL-
D5-Diag
4. D5_Step: Step+ → PUL+
5. D5_DIR: DIR+
6. +3.3V: Enable+
7. GND: DIR-
V_Fused
GND :

D6_DIR:
5V_INT
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.

I am using smps 24V output.

Have you seen this?

@eznish most likely your stepper motor driver needs more voltage and current than the Duet 3 Mini provides on those pins. You can use a 74LVC06A chip powered from 3.3V or a 74LS06 chip powered from 5V to provide open collector/open drain outputs more suited to those drivers. Then use the common anode connections shown in fig. 5.1 of the driver manual.

We have plans to produce a daughter board to do this level shifting, but it's not the top priority at present.

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

@eznish
Yes. I found this document and follow this instruction.
