Hi all, I am desperately needing some help, my creality Ender-3 v3 se 3D printer has been working fine for the last 6 months. Yesterday I left something to print and then came back to check on it and it has started failing prints, it starts off fine and then just starts printing side to side. The bed is not moving backwards and forwards properly and literally got stuck at one point. I have checked underneath and nothing is stuck under there. Its also making an awful creaking noise when printing, I have bought some oil to see if its just the case of the belt needing lubrication but I wondered if anyone else had any ideas?
Does the bed rock on the linear rails? Is the bed securely fastened to the bed carriage? Are the bed carriage to linear rail fixings tightened? Are the nylon wheels on the x gantry tightened/adjusted?
