The Ultimaker Z Motor with Trapezoidal Lead Screw for the UM2 is a complete OEM replacement unit for the vertical axis drive system of the Ultimaker 2. The Z-axis motor drives the build plate up and down via the lead screw, with each step corresponding to a precise layer height increment. A worn or failing Z motor can cause inconsistent layer heights, Z-axis stuttering, banding in prints or complete vertical axis failure.

This genuine Ultimaker unit includes the stepper motor and integrated trapezoidal lead screw as a matched assembly, designed to bolt directly into the UM2's Z-axis frame without modifications. Replacing the Z motor with an OEM assembly ensures the correct step angle, lead screw pitch and mechanical tolerances are maintained, preserving the printer's Z-axis resolution and layer consistency. For the UM2 Extended, see the Ultimaker Z Motor with Trapezoidal Lead Screw UM2E (210000001409).
