# Z-Axis Stage

The Prusa uses dual integrated leadscrew motors to raise/lower the X gantry in the Z-Axis. With the Z-axis, the usual problems revolve around making sure the X gantry is being lifted equally on both sides and not tilted. This can be remedied with the in-built software with the MK3S. Steps to perform it can be found here:
