Lifting print

[Paul M]

has your filament been sitting outside for a while? It can pick up humidity and cause problems.

[Paul M]

there’s all sorts of calibration tests you can download from thingiverse that can help you pinpoint the problem (and usually are faster to run than trying to print a big part).

But if you switched filaments and you’re having a problem it seems likely your filament isn’t good.

What Paul said. I was having problems with warping and tracked it down to damp filament. I’m also finding that dried filament isn’t quite as good a freshly opened.

One last thing. What plastic ? Are you trying to print something that needs an enclosure to keep from warping ?

The brim is helping the outside but these little guys inside are lifting. It’s Probly the filament. It’s been open about a month. I keep it in a ziplock with the silica. But Probly doesn’t help much. I used some glue stick, turned up the bed, and turned off the fan for the first few layers. This progress pic is the best I have had from this spool.

I was having adhesion issues on my Ender 3 after about 18 months of flawless printing. The culprit for me was the coating on the bed and I read from other users that this is a common issue. Perhaps this is the case with your setup as well. To remedy things, I flipped my glass bed over (texture side down, now) and every print I now make, I first give the bed a light coat with a glue stick. Windex on some paper towel dissolves the glue in short order for clean-up between prints. I’ve not had an adhesion issue since.

Ahhh the smooth side. I will try that if the one I am running now doesn’t work. I am trying a slightly newer filament. We will see how it goes

I got the print to work very cleanly. I printed the first few layers without the fan. Then had it at a lower setting. I put an inner and outer brim on, which I think was the secret ingredient. Had the bed temp raised up. And I did swap out for a newer filament. To be honest, after changing the settings I don’t know if it would have made a difference or not. I will Probly try running one with these settings in the other Filament later to see if it makes a difference or not.

Hiya! Try slowing down initial layer speeds, increase bed temp, make sure bed level is perfectly flat. Change to a fresh brass nozzle,(I’ll change mine at least once a month) increase surface area of brim with tabs plugin. Make sure filament is super dry, and printing environment is at a constant temp and humidity.
