Frequently Asked Questions

screw (otherwise known as a grub screw). These set-screws anchor
the pulley to the shaft of the motor so that the two items spin
together. However, if the set-screw loosens, the pulley will no
longer rotate together with the motor shaft. This means that the
motor may be spinning, but the pulley and belts are not moving.
When this happens, the toolhead does not get to the desired
location, which can impact the alignment of all future layers of the
print. So if layer misalignment is a reoccurring problem, you
should verify that all of the motor fasteners are properly tightened.
There are also several other common electrical issues that can
cause the motors to lose their position. For example, if there is not
enough electrical current getting to the motors, they won’t have
enough power to spin. It is also possible that the motor driver
electronics could overheat, which causes the motors to stop
spinning temporarily until the electronics cool down. While this is
not an exhaustive list, it provides a few ideas for common
electrical and mechanical causes that you may want to check if
layer shifting is a persistent problem.
