My Ultimaker 1 is becoming misaligned along the x-axis.
I have checked the belts by loosening the motors, pushing down and tightening and by adding belt tighteners where required. I have also tightened the pulleys (although they are quite hard to reach!).
The abnormality I can see is the small x-axis motor belts appears to be warped and twists slightly compared to the one on the y-axis. I have recorded a video of the difference here (
I'm not sure if this is cause of my problem. If it is does anyone know of a solution?
If this is shouldn't affect my print does anyone have other suggestions of what the cause might be?
