Preparing The Drive Motors - SeeMeCNC rostock max v2.0 Assembly Manual

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.
Fig. 5.1-1: Flatted shaft.
Fig. 5.1-3: Drive gear
installed.
Complete the gear installation on the other
two motors. Set aside when done.

Thread both of the grub screws into a drive gear
and then slide it on to the stepper shaft as shown. Make
sure that a grub screw is aligned with the flatted
portion of the shaft. You also want to make sure that the
end of the stepper shaft is flush with the outside face of
the drive gear – again, as shown below.
