Prusa Mini+ - Troubleshooting Layer/Axis Shift

1. Check Belt Tension

• Ensure that the belts on the X and Y axes are properly tensioned. Loose belts can lead to print inaccuracies.
• For guidance on adjusting belt tension, refer to the following resource:

• Adjusting belt tension (MINI/MINI+) | Prusa Knowledge Base (prusa3d.com)

2. Inspect Freedom of Movement

• Verify that the X and Y axes move smoothly without any obstructions. Manually move the print head and bed to check for any resistance.

3. Evaluate Print Adhesion and Sheet Slip

• Prints should adhere firmly to the print sheet.  
• Ensure the print sheet is strongly magnetized and that it isn’t shifting during printing. It should take some force to move the sheets; if it slides or slips easily it should be replaced. 

5. Additional Issues

• It is also possible that poor print quality is causing blobs that catch on the nozzle. Refer to general print issues troubleshooting:
