How to Fix Layer Shifting (Layers Offset Mid-Print)

Step-by-step fix for layer shifting (layers offset mid-print) on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix layer shifting (layers offset mid-print)?

1
Reduce print acceleration to 3000–5000 mm/s² and max speed. Layer shifts happen when stepper motors can't keep up with commanded movement.
Setting: speed.accel.normalPrinting
2
Check that belts are properly tensioned and pulleys are tight. A loose belt or a slipping pulley allows the toolhead to skip position during fast moves.
3
Ensure the print isn't catching on the nozzle. Enable Z-hop during travel and check for warped areas that stick up.
Setting: Z-hop

Pro tip: Layer shifts often occur at extreme speeds. Select "Fast Print Speed" above for optimized speed settings that push throughput without exceeding your printer's mechanical limits.
