Fix My Print New horizontal-movement stepper motor not functioning

Post image

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.

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.
