Im very new to 3d printing and this is my first time using anything other than pla. So far all of my prints are lifting off the bed at the corners. They start off looking beautiful. No stringing, great adhesion, etc. But after a few layers, they start to come off. Especially on larger prints.
Heres my setup:
- Ender 3 pro with skr mini e3 v2
- Creality Ender 3 glass bed upgrade
- Bed temp: 90C
- Extruder temp: 240C
- Nozzle diameter: .4
- Layer height: .2
- First layer: .45
- Speed: 60mm/s
- Slicer: Silc3r
I realize that asking this question is like asking WebMD to dianose my sniffles, cause it can literally be anything, but Im hoping someone with more experience can give me some pointers on what works for them. Thanks yall!
Update: First of all, thank you all so much for the kick ass suggestions! I really appreciate all of your replies. Since pretty much everyone recommended it, I went ahead and got a textured spring steel PEI plate and holy shit, it didn't disappoint. Adhesion has been fantastic. I also ended up lowering my bed temp down to 75 from 90 and pushing my hotend temp to 245 for the first layer, then back to 240. I got an enclosure to help keep the plate clean but I also stocked up on some blue dawn dish soap. I still have a little more trial and error with print speed and cooling but I'm literally getting the best prints I've ever gotten thanks to all of your suggestions. Yall are awesome and I'm really glad I posted here.
It's very sensitive to temperature so try running with the fan off or at a very low setting. You can also try stuff like hairspray to promote adhesion, or a textured buildplate/sticker
