u/Nikkoin

In the middle of a print it just started making sounds, and it didn't have the strength to pull nor push anymore. The other 3 channels work fine. I tried to find a solution but it seems that I would need to open the BMCU to see the problem, maybe related to the gears? But I don't understand this stuff. I bought mine completed, I didn't build it.

Does anyone know a tutorial for this? Thanks!
