Z leadscrew alignment tools

Updated 2026-05-26

Proper alignment of the Z leadscrews is essential for smooth and quiet bed movement. Misaligned leadscrews cause increased resonance, vibration, and noise during bed travel.

The problem

When Z leadscrews are not properly aligned with their mating nuts, the bed movement generates excessive vibration and noise. This is a common issue on the Core One due to the assembly tolerances.

Tools

Print the front and back alignment tools, then follow the forum guide to align your leadscrews. This significantly reduces resonance and improves print quality during Z-axis movements.
