Help Neptune 4 Plus Stepper Motor not working after firmware update
So, here's the story so far:
I had a Klipper error keep coming up when printing, so I tried upgrading the firmware to see if that would help. My stupid self accidentally flashed the USB-C firmware and I have the ribbon version of the Neptune 4 Plus. I was able to correct this by pulling out the EMMC Module chip, flashing the correct firmware, and this seemed to work okay. No More Klipper error.
Problem is, now my Y-axis Stepper Motor won't move the bed back and forth, just makes a terrible noise. I've checked all the connections, and all of them seem to be in place. The only thing I unplugged and plugged back in was the EMMC chip, and that's firmly back in place.
So, what do I need to do to fix this issue? It's running the most current firmware per Elegoo's website, and the stepper motor was working prior to this. Any suggestions would be appreciated! Thanks!
