Installing the Drive Gears on the Stepper Motors

For this task, you'll need the following components:
Three Stepper Motors
The stepper motors that are shipped with your Rostock MAX v2 kit are equipped with a
"flatted" shaft. This means that a portion of the drive shaft has been ground flat. This ensures that a
properly tightened drive gear won't be able to rotate on the shaft when properly tightened.
Thread one of the grub screws into a pulley and slide the pulley on to the stepper shaft as
shown. Make sure that the grub screw is aligned with the flatted portion of the shaft. You also want to
make sure that the tip of the stepper shaft is flush with the outside face of the pulley – again, as shown
below.
