The device makes louder than normal noise during travel and is frequently slipping.
This condition happens if the thrust needed is more than the thrust available from the device.
Check the following:
The force on the device is less than the maximum thrust.

Test the following:
Try a slower target velocity. Stepper motors produce more thrust when moving slowly.
Try a lower acceleration and deceleration.
Clean the screw and lightly re-grease it with a grease that does not degrade plastics.
The device has repeatability errors smaller than 4 full steps.
If steps aren't being skipped, friction or loose parts may still cause some variation when
returning to a position.
