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 adheasion, 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!
You need to raise your z-offset. PLA should be squished onto the bed. PET-G needs to be laid down neatly. If you try to squish it then the next layer snags on it because it’s tacky and it causes it to lose adherence. Raise your z-offset by 0.02-0.15mm. It’ll require some experimentation.
You also need a much hotter bed. I use 60c for PLA and 90c for the first layer of PET-G and then 85c for every other layer.
Ultimately what worked best for me was getting a spring steel bed surface. I never had much luck with PET-G on the glass or default bed surface. As soon as I got a spring steel bed all of my problems were solved.
