Shifted layers (layer shift)
7 usi3d guides for “Shifted layers (layer shift)”, each with the likely causes, how to check which one is yours and the step-by-step fix, with each manufacturer's official sources.
4 apply to any FDM printer and 3 are for Bambu Lab and UltiMaker printers.
Each guide summarises the official documentation and says whether usi3d has already verified it on a machine.
Any FDM printer (4 guides)
- Layer shift: the print steps sideways in X or Y
From a certain height, the layers are offset to one side compared with the ones below, like a step.
- Loose pulleys or grub screws: shifted layers, play and noises in the axes
Layers shift like a staircase in X or Y, you feel play when moving the toolhead or the bed with the motor still, the belt runs crooked or an axis makes a strange noise…

- Replacing a worn or broken belt and tensioning it properly
The belt has broken teeth, cracks or frayed edges, or it has snapped; or, even after tensioning it, the layer shifts or the noises when the axis moves come back.
Bambu Lab (2 guides)
- H2D: the two nozzles don't line up (shift when switching nozzles) or nozzle offset calibration fails
In a print using both nozzles, what one nozzle prints is offset from what the other prints, like a step or a layer shift right at the nozzle change, or the nozzle offset…
- Tensioning the belts on the X1, P1, A1 and H2D (oval circles, ringing or tension alert)
Circles come out oval, ringing or dimensional errors appear, the printer warns after calibration that a belt needs tensioning (the A1 asks through an HMS alert) or it…
UltiMaker (1 guide)
- UltiMaker S: the two materials do not line up or there is a layer shift when switching print cores
On an UltiMaker S series printer, in prints with two print cores the colours or materials are shifted relative to each other (for example, the support does not match the…
