Intro
Layer shifting creates a sudden “stair step” in your print when the toolhead or bed skips position. It looks catastrophic, but the causes are predictable. Work through this checklist and you’ll fix it fast.
Mechanical culprits
- Loose belts: tighten until they “twang,” not slack.
- Pulley grub screws: ensure set screws clamp the motor flats.
- Frame not square: check gantry alignment; tighten corner brackets evenly.
- Linear guides binding: look for debris; clean and lightly lubricate if recommended.
Motion/print dynamics
- Collisions: curled corners or tall narrow features hit the nozzle—improve cooling, add Z-hop.
- Too aggressive speeds/accel: reduce acceleration and jerk values.
- Wobbly table: move to a sturdy surface; avoid shared desks.
Electronics & drivers
- Overheating drivers skip steps—ensure airflow and heatsinks.
- Stepper current too low/high—use sane defaults; avoid extremes.
- Loose connectors can intermittently drop power—reseat plugs.
Prevention habits
- Run a quick belt/pulley check each month.
- Use brims and stronger adhesion so parts don’t curl into the nozzle.
- Preview for tall, thin towers—print slower or add supports.
FAQ
Shifts at the same height? Usually a collision at that layer—look for overhang curl or support contact.
Only on fast prints? Reduce acceleration; speed amplifies wobble.
Wrap-up
Tighten, cool, slow, and stabilize. Layer shifting is solvable with a few mechanical checks and calmer motion settings.
