This part includes another stepper motor. A bit of care is needed when dealing with these motors because they are not all the same and the shafts they use differ as well. In particular the shafts are of different lengths with different thread pitches (the z-direction shafts for the platform and the syringe have much finer threads). The syringe motor is different from the others in that the shaft moves up and down through the centre of the motor as it turns to allow it to press and release the syringe plunger. The other motors simply hold and turn the shaft so that the parts attached to the shaft move in the x-, y-, and z-directions.
