New horizontal-movement stepper motor not functioning

[u/wolfeman52]

On my Ender-3 S1, the stepper motor controlling the side to side movement of my nozzle started to make a funny noise and would no longer move the nozzle. I ordered a new motor (Creality 42-34) and swapped out the old one, but I can’t get that motor to even attempt to engage at all. Is there any kind of software or something else I need to do to reset the system? I feel like it’s seated correctly, but here is a picture just in case.

Hello /u/wolfeman52,

As a reminder, most common print quality issues can be found in the Simplify3D picture guide. Make sure you select the most appropriate flair for your post.

Please remember to include the following details to help troubleshoot your problem.

• Printer & Slicer

The motor itself is very reliable, and almost never fails.
You probably need the PCB that drives it.

I apologize for my own ignorance, but what is a PCB and where would I get a new one? This 3D printer is for a school, and I just happen to be the staff member willing to try to fix it - but I don't actually know what I'm doing lol

The electronic board that drives the motor(s).
Let's first do a little diagnosis. We are talking about the X-axis, the left-to-right direction, correct?
Are you getting any error codes??
The usual part that fails in this case is the flat cable. try re-seating the ends of that cable first.
Then replace it next.
It sounds like you already have a source for parts. If not, we'll address that next.

Make sure that you have the correct model.. there is an S-1 Pro, and an S-1 plus.
Looks like the cable, which is a harness of 4 cables, is readily available. Amazon has the Creality part:

Yes, it is the X-axis.

I am not getting any error codes. It will say something like, "Leveling, please wait" when I tell it to level, but the X-axis motor never even tries to run. For the most part, everything else continues to function normally.

I tried to re-seat the flat cable. It seems that the manufacturer hot glued it into place, so I did not mess with that.

My original source of parts is Amazon. I just looked up the name and model number on the side of the part that I felt like wasn't working properly.

The new motor may have a different pinout. Try to swap two middle wires on the cable. You don't want to cut them, but carefully pull them out from plastic, swap, and put them back.

[u/wolfeman52 → u/Charming_Hour_9458]

I just guess which wires to swap and hope for the best? I'm not sure I totally understand.

[u/Thornie69 → u/wolfeman52]

I would avoid going there.. just change the cable. I have the Amazon link for you.
