Bed Leveling Guide
Unlevel beds are a common issue with most FDM 3D printers. Because these beds sit on springs and are generally exposed to large heat fluctuations, beds can easily become unlevel with time.

Symptoms of an Unlevel Bed
If a 3D printer has an unlevel bed, there are a few symptoms that may arise.
- Filament does not stick to the bed and "spaghettifies" (see Figure 1)
- Filament is not properly "squished" between layers (see Figure 2)
- On the first layer, the filament is too squished and the nozzle is rubbing on the bed (If this is the case IMMEDIATELY stop the print!)
- Filament is warping during the print
- If you notice symptoms 1 or 2 occurring, the nozzle is not close enough to the bed.
- If you notice symptoms 3 or 4 occurring, the nozzle is too close to the bed.
Fixing an Unlevelled Bed
Thankfully, fixing an unlevel bed is very easy and can be done by those with very little 3D printing experience. Below are in depth guides to fixing this issue on different printers.
Prusas
The Prusa Mk3s that we have in the processing section is equipped with an auto levelling bed. If any of the aforementioned symptoms arise, there is another issue at work. Please contact a TO or the CTO in this case!
