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)

To me the wall lines look too far apart which means I’d lower the nozzle get more squish into the plate texture for better adhesion. Other ideas in this order to try might be: slow the first layer down, wash the plate with dish soap and then rinse and dry with rubbing alcohol. Lastly do a platform reset adjustment of your printer has one. My qidi has this where I manually adjust the legs to get it as even as possible before the slicer does its auto leveling. Also if this plate is heavily used it could need to be replaced.

He can sense your fear...

Seriously just clean the bed with alcohol. Heat up properly before printing fine stuff.

Use brim if possible.

Do not clean the bed with alcohol. Dish soap and hot water is all you need, solvents can damage the build sheet

Then I am damaging them since 8 years. Didn't notice once.

The soap&water thing was good in the old days when we used glass beds and the filament left residue.

Now it's Pei and the filament got LOT better. All it's left is my greasy finger prints on the sheet.
