Lifting corners and how to deal with this is too complicated to explain here especially since I spent dozens of hours getting it all down into one 15 minute video. Or maybe you used to have rounded corners or brim and decided sharp corners are better. Or maybe what changed is your models are larger or you increased infill percentage (which pulls inward on the upper layers applying more stress). Or maybe something is wrong with auto leveling (it's important that the spring in the core is stronger than the springs in the bed but in this case it levels too low which means it sticks better so I doubt it is that). There's 3 easy ways to get liquid pva onto the glass. I like to wash in a sink with soap and water and scrub it well, then rinse, then wash with glass cleaner then dry with paper towel and then give it a coating of PVA mixed with water. Have tried running the bed a bit hotter (60C) which has helped a bit although not completely eliminated the issue, but we then get the issue of lower wall cave-in happening ? We clean the plate using isopropyl alcohol, never found the need for glue/hairspray etc and have normally found 54C to be plenty for the PLA to stick quite well - plus it reduces the chance of lower wall cave-in. Does it kind of wear out? We have actually been doing a LOT of prints over the last few months, and I was unsure as to whether over time/use the ability of the glass bed to 'stick' to the PLA may reduce? We haven't changed anything to what we were doing before (settings, bed levelling, filament used, cleaning of build plate etc) - so I am wondering if it may be due to the glass build plate itself. Until recently we have had no issues with lifting/warping of our PLA prints - often struggling to remove prints from the build plate - but it seems like all of a sudden we have started having the issue of prints lifting/warping at the edges.
