V-Wheel Wobble Fix Guide

Quick diagnosis

Fix loose or tight V-wheels by adjusting eccentric nuts, checking flat spots, and confirming smooth carriage motion.

Most likely causes

• A mechanical change, slicer setting, or material condition is making the printer behave differently than the profile expects.
• The problem is often made worse when multiple settings are changed at once.
• Moisture, worn parts, loose hardware, and old profiles can create symptoms that look similar.

Step-by-step fix

1. Move the axis by hand with motors disabled.
2. Adjust eccentric nuts until wobble disappears without binding.
3. Replace damaged or flat-spotted wheels.
4. Re-check after the first few long prints.

Before you buy parts

Save your current slicer profile, test with a small repeatable model, and change only one variable at a time. Many 3D printing problems can be fixed with cleaning, calibration, or profile tuning before replacing hardware.
