Does not stick to the bed
14 usi3d guides for “Does not stick to the bed”, each with the likely causes, how to check which one is yours and the step-by-step fix, with each manufacturer's official sources.
3 apply to any FDM printer and 11 are for Bambu Lab, Creality, Elegoo, Flashforge, Prusa, Qidi and RatRig printers.
Each guide summarises the official documentation and says whether usi3d has already verified it on a machine.
Any FDM printer (3 guides)
- ASA: the corners lift and the part comes off the bed mid-print
With ASA, the corners of the part curl upwards after a few layers, the base comes away from the plate and sometimes the part comes off completely mid-print or the nozzle…
- First layer won't stick to the bed
When the print starts, the plastic doesn't stay on the bed: lines drag, curl up or stick to the nozzle, or the part comes loose shortly after starting.
- Supports that fall over, break or won't come off
Supports come away from the bed, bend or break during the print, and the area they held comes out badly or collapses.

On the A1 or A1 mini the first layer comes out too squashed, wavy, with raised edges or peeling off, or the nozzle almost rubs the plate and hardly any plastic comes out.

- First layer too high, too squished or uneven on MK4, MK4S or CORE One (load cell)
On an MK4, MK4S or CORE One, which calibrate the first layer by themselves with the load cell in the print head, the first layer comes out too high (round lines with…
- MINI+: wrong first layer height, Live Adjust Z at its limit or Z rises while leveling (SuperPINDA)
On the MINI+ the first layer is too high or too squished, Live Adjust Z reaches -2.000 and the nozzle is still too far away, or during homing or mesh bed leveling the Z…
- MK3S+: wrong first layer height, nozzle hits the bed or bed leveling fails (SuperPINDA)
On the MK3S+ the first layer is too high or too squished, the nozzle scrapes or crashes into the sheet, XYZ calibration fails, or you see «Bed leveling failed.
