The Ultimaker Z Motor With Nut for the S5 is the original Z-axis stepper motor and lead nut assembly that drives vertical movement of the build platform on the Ultimaker S5. The motor and nut work together to convert electrical motor steps into precise, incremental Z-axis movement, controlling layer height accuracy across the entire build. A failed or degraded Z motor assembly results in incorrect layer heights, Z-axis positioning errors and, in severe cases, complete loss of vertical movement.

This complete assembly - motor and nut together - simplifies Z-axis drivetrain replacement and ensures that both the drive source and the mechanical interface are renewed simultaneously for optimum performance. Replacing with this genuine Ultimaker assembly restores factory-specification Z-axis movement and layer height accuracy on the S5.
