I am currently facing an issue during printing where the x-axis goes out of level after a while i.e. measuring the distance from the bottom of the X axis smooth rod and the top surface of the Y axis aluminum bed plate. I noticed while printing halfway, the left z-axis motor stopped moving while the right z-axis motor continued to move and the x-axis went extremely out of level of about more than 1cm. This flattened the z-axis of the print basically as the left side was not able to move.
I did some troubleshooting and realised the left motor turns with more resistance than the right motor and suspected too much friction in the left threaded rod at the top and bottom bearings. I oiled the parts and the threaded rod rod turned a bit better this time. Thereafter I ran cura and did increments of 0.1mm to simulate a print going on and realised after doing like 20 to 30 times the x-axis still goes off by about 1-2mm after leveling it.
Any ideas on how to fix this or suggestions as to what is going on? Thanks!
