hello! I got y-axis problems while printing. It seems like the printer does not know correctly the position of y-axis. The Printer worked fine. Then a fan made sounds. I opend the printer underneath, changed the fan and closed it. Just wanted to print something. And then this happens. (Attached pictures) I checked already the cables, they seem to sit correct. My printer is from kickstarter, no changes of firmware. Before changing the fan the printer worked fine. I proofed to print from files/models which worked correctly already. Thank you for suggestions.
