Z-Axis Anti-Backlash Nut
The anti-backlash nut is responsible for maintaining a tight, repeatable interface between the lead screw and the Z-axis carriage. If the internal spring-loading mechanism fails or the brass threads wear down, the carriage can shift slightly during the high-suction forces of the FEP peel cycle. This results in the characteristic 'wobble' or Z-banding visible on the finished print.

MGN15 Linear Rail Carriage Block
The dual linear rails are intended to constrain the Z-axis to purely vertical movement. If the ball bearings within the carriage blocks develop flat spots, lose lubrication, or sustain damage from resin contamination, they allow for lateral play. This allows the building platform to tilt slightly under the varying load of the resin vat suction, creating layer misalignment.

Flexible Plum Coupling
This component connects the Z-axis stepper motor to the lead screw and is designed to dampen vibration and compensate for slight misalignments. If the elastomer insert (the 'spider') perishes or the set screws loosen, it introduces eccentric rotation (runout). This oscillation is transmitted up the lead screw, manifesting as a periodic wobble pattern in the printed geometry.
