Gantry Not Level Fix

Quick diagnosis

Fix a tilted X gantry by checking frame square, Z lead screws, eccentric nuts, belt sync, and mechanical binding.

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. Power down before manually checking gantry movement.
2. Measure both sides from the frame or bed reference.
3. Check Z wheels and screws for binding.
4. Re-run Z-offset and mesh after adjustment.

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.
