I learned that on my Lego printing experiment. You want to print Lego raftless (and big things, Im not talking lego blocks, Im talking entire lego cars on one plate) and I did find that when it was too hot I was killing my kapton tape, then after a week with my printer I figured out that the hotbed setting needs to be set for each filament - and 1 or 2 degrees can make a MASSIVE difference. Generally I have found that unless I am dying to print fast and don't want to wait for the next preheat then sure, i'll knock them off - but you do it quick as in 'SMACK!!!" none of this pulling like a sissy lol, you won't de-level your platform if you do it fast enough.
Or just wait till it cools down - a correctly heated bed for the right plastic won't stick, i'll give you 100 kilograms of plastic guarantee on that one (well maybe not 100.. im probably on my 60th roll - my machine is printing non stop every day except for when i go to bed, I never run it overnight. Just me, Im paranoid.
