Ender-3 V3 SE - Everything seems to print fine overall but at some point almost at random the nozzle will start catching on the print. Pic one shows how all my layers seem good and smooth, and pic 2 shows where my last print died. it seems like it’s catching on the infill. It’ll catch then pull it off the bed. How tall the print is doesn’t seem to make a difference.
I don’t know if its related but i often have issues with bed adhesion. I got a PEI bed…
Looking at your second photo, to me it looks like over extrusion is causing you issues.
When you push too much filament out it produces those bubbly walls, it also means there is less room between the nozzle and the print, which at height leads to the nozzle scraping and applying too much force to the print… which leads to the print being ripped off the bed… no matter how clean the bed is, glue and raising offset during print can assist, but doesnt fix the underlying issue. Just masks it.
Suggest you print the flow combination calibrations to correct flow for this filament brand/type, save the calibrated flow as a user profile so you have it going forward.
Edit, my guess is that you are using a non-creality filament, & using the CR* filament profiles.
