I have been noticing some binding/grinding sounds lately as the X rail travels up/down along the Z-axis. I’ve noticed that this is happening due to the X-axis rail not being level with the frame. After manually leveling the X rail - by measuring each side against the frame and manually rotating the left/right stepper motors - the binding/grinding stops.
After each print, or manually moving the Z-axis, the X rail becomes skewed again. It’s more apparent over a longer set of traversing moves and in print quality. I’ve come to the conclusion that the issue lies within the Z-axis motors.
Is there a way to calibrate/fix this motor issue, or do I need to just replace both motors?
Thanks in advance!
