Frequently Asked Questions

either of those speeds are too high, it can cause shifting to occur. If
you are comfortable adjusting more advanced settings, you may
also want to consider lowering the acceleration settings in your
printer’s firmware to provide a more gradual speed up and slow
down.
(2) Mechanical or Electrical Issue
If the layer misalignment continues, even after reducing your
print speed, then it is likely due to mechanical or electrical issues
with the printer. For example, most 3D printers use belts that allow
the motors to control the position of the toolhead. The belts are
typically made of a rubber material and reinforced with some type
of fiber to provide additional strength. Over time, these belts may
stretch, which can impact the belt tension that is used to position
the toolhead. If the tension becomes too loose, the belt may slip on
top of the drive pulley, which means the pulley is rotating, but the
belt is not moving. If the belt was originally installed too tight, this
can also cause issues. An overtightened belt can create excess
friction in the bearings that will prevent the motors from spinning.
Ideal assembly requires a belt that is somewhat tight to prevent
slipping, but not too tight to where the system is unable to rotate.
If you start noticing issues with misaligned layers, you should
verify that your belts all have the appropriate tension, and none
appear to be too loose or too tight. If you think there may be a
problem, please consult the printer manufacturer for instructions
on how to adjust the belt tension.
Many 3D printers also include a series of belts that are driven
by pulleys attached to a stepper motor shaft using a small set-
