Ok, I'm finally back and able to work on the printer again. I connected all of the wires as I stated in the previous post of mine. Sadly, I am getting no input to the drive whatsoever.

Things that may be causing an issue:

• ENA+ is said to require +5V at the driver instead of the +3V I had previously listed.
• Possibly improper from my coding of the M584 command.
• Possible incorrect pinout from my previous post.

@dc42, you have been awesome so far and I feel like I'm getting very close! Any help is appreciated!

Ok, I think I am headed along the right path now. As far as I know, the code input into the config file should be:

M584 X0 Y5 Z2 E3

X mapped to the initial drive 0, Y mapped to first extruder on expansion header (5), Z mapped to initial drive 2, and the extruder mapped to the initial drive 3.

Now that that is taken care of, the only thing left to handle would be the pins at which i need to connect [PUL+, PUL-, DIR+, DIR-, ENA+, ENA-]. So if I'm not mistaken, the pinout I need to connect to should be:

ENA+ > Pin 3 [+3.3V]
ENA- > Pin 24 [PC20]
PUL+ > Pin 19 [PC7]
PUL- > Pin 2 [GND]
DIR+ > Pin 20 [PB14]
DIR- > Pin 2 [GND]

Edit: Sorry for so many questions and such, I'm not the best at programming and such. I am much better with 3D and mechanical design.

I believe that is exactly what I'm looking for! I didn't see those raw stepper outputs on the DueX4 but I'll look again, I'm sure they're there somewhere.

I appreciate the help! I'll be able to work on it later today sometime hopefully!

I do have the DueX4 expansion card, but I do not believe it is entirely necessary for the situation. I need a 3+ amp output for the motors, and as far as in know the Duet 0.8.5 and DueX4 expansion cannot supply that current. Hence the reason for me needing external steppers.

I appreciate the reply!

Hello! I have been using my computer for a while now and have had an issue with the Y-axis motor not being stong enought to fully manage the massive bed I am using. I now have a Nema 23 motor ready to be used on the printer but I have no clue on how to manage the software to add a external stepper driver.

Hardware:
Nema 23 Stepper 4-wire
Duet 0.8.5 Ethernet
DueX4 Expansion Card
M542T Stepper Driver

This is the current list of items that may be applicable to the situation. The stepper driver has the typical [ A+, A-, B+, B-], [ PUL+, PUL-, DIR+, DIR-, ENA+, ENA-], [ DC+, DC-]. I just have no idea on how to manage the software. Ill add the config file below. Any help would be appreciated!!!!
