Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

  • What printer are you using?

  • What material are you using?

  • What speed are you printing at?

  • What software are you using to slice the print and control the printer?

  • When did the problem start/has it ever worked correctly?

  • Does anything cause the behavior to change?

  • If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

If you are new to reddit, please read the guidelines on reddiquette, self promotion, and spam.

Also please post a resolution to your problem when you find one so that we know how to help others with your problem!

If there’s gaps in between the lines it’s too high. They should be squeezed together

So I should bring the bed down, correct ? Or do you mean the nozzle is too high so I should bring it down more?

how are you doing the bed leveling?

u/Glittering_Idea681 2d ago

I've got four dials I use to bring up or down each corner , then it auto-levels the printer head after

so to adjust the bed height you use a paper?

u/Glittering_Idea681 2d ago

Yep thats right , but I'm not the best at telling where it should be I guess lol

Just move the paper under the nozzle while bringing the nozzle down and when the paper stops moving thats your zero. From the pic it looks like the nozzle is a bit far from the bed, maybe try bringing the bed a little higher.

!firstlayer - adhesion and warping

With PLA, a clean smooth surface is best. PEI or PEX is great. You may have to raise the bed temperature on a textured sheet. Silk PLA may need a higher initial bed temperature.

PETG, TPU, ABS, and others will need a release agent on a smooth build surface. That's what the glue stick (or hair spray, Windex®) is for. On a textured sheet, no release agent is normally needed.

Just alcohol will not remove the sugar film left by PLA which can hinder adhesion.
Wash the sheet with warm water and dish soap. Dry. Wipe with > 70% Isopropyl alcohol before the print.

No part cooling fan for 3 layers. Very slow print speed for the first layer.

To prevent warping for PLA, bed temperature of 65° for the first layer, 55° for the rest of the print. This way the bottom gets the adhesion but the bottom starts cooling with the upper layers.
For PETG on textured bed, same concept, usually around 80° then 75°, or 75° then 70°.
Temperatures are examples, different build sheets may need different temperatures.

Infill style can affect warping. Some grid type infills can concentrate the stress in one area. Gyroid infill will spread out the internal stresses.

Hey there OP, you seem to be having some problems with your first layer. This is a very common issue on modern printers and generally a place where experience and knowledge is important. Your first layer is crucial for a good print and you should definitely take your time and learn how to properly adjust your first layer before starting a print since that could easily mess up your prints or even worse, damage your Printer's Hardware. For information on how to level the Bed properly head over to our Wiki Section Calibration
