Quick diagnosis
Track down repeating horizontal bands by checking Z screws, wheels, frame alignment, flow consistency, and slicer artifacts.
Likely causes
- Bent or dirty Z screw
- Binding motion
- Loose wheels
- Inconsistent extrusion
Step-by-step fix

- Verify frame squareness.
- Look for periodic band spacing.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
