What is the purpose of printer levelling?

3D printer levelling in 10 steps

1. Before starting, ensure the print bed is tightened to its lowest point and your Z-offset is set to 0, this ensures the print nozzles will not crash in to the print bed. You can do this by slowly tightening the wheels on each corner compressing the springs.
2. Ensure the build plate is clean, free from grease and dust.
3. Get the machine up to normal temperature to suit your normal print material, for example 60 degrees C for PLA. Be sure to remove any filament from the extruder and clean the nozzle.
4. Home the machine and disable the stepper motors.
5. Starting at the front left corner, place a sheet of paper on the bed, raise the corner using the adjustment wheels under the bed until light friction is felt between the nozzle and print bed. This step should be done gradually to avoid wrapping the bed, so turn each wheel a little at a time until you reach the point you're looking for on all four corners.
6. Slowly move the extruder to the front right side of the print bed and repeat the process.
7. Continue around the remaining two rear corners, again repeating the same process.
8. You should finish the levelling process in the centre of the print bed.
9. Repeat these steps 2 or 3 times to achieve the best results, working your way around the print bed and finishing in the centre.
10. Once you have completed these steps you can start a test print and fine tune your Z-offset to achieve the best results.

Can a print bed also be levelled automatically?

When should I re-level my printer?

• The print does not 'stick' to the print bed
  • A first layer is crucial for a good print. It must therefore be properly attached to the printing surface. If the distance from the nozzle to the print bed is too great, the filament will not stick enough and will come loose. To prevent this, we recommend the use of 3DLAC adhesive spray. Incidentally, there can also be other causes, as a result of which the filament does not stick. Quickly learn how to fix this problem.
• Holes appear in the first layer or the layers are too thin
  • If the print bed is not completely straight, holes may appear in the first layer. This is because the nozzle is not continuously at the same distance from the print bed. To fix this, you need to re-level your printer. Curious about how under extrusion can even arise? Check out this common problem.
• Excess plastic remains after the first coat
  • If the distance between the nozzle and the print bed is too small, you can suffer from filament blobs. This can cause the print to come off at a later time, it also affects the alignment of the entire print and the nozzle can become clogged. On this page, you will find more tips to prevent blobs or bumps.
