TAZ 5 Grinding filament and not extruding material.

EDIT: SOLVED

are you talking about the two shiny smooth rods bearing rods? How “not level” are they? do you have a picture you can upload? Is one side of the X axis just higher than the other, or are the rods themselves actually bent? if the sides are just not level, you can re-level them by turning the printer off, unplugging the A axis motors, then manually turning the leadscrews until the distance from the bottom of the Z leadscrew nut to the top of the Z motor mount lower bearing is the same on both sides when measured with calipers. Then reconnect the motors and print bed calibration objects and check the bed level at the nozzle with a feeler gauge, etc.
