I've bought a new crystal bed for my Ender 3 because the one that comes with the printer was kind of worn out and not very beautiful. But after my first printing I find it impossible to remove the piece, it's stuck as hell. I've tried everything I've seen on the Internet:- Putting the crystal bed with the piece in the freezer for 15 minutes - Reheating the bed with the plate on- Using a 50% alcohol and 50% water solution to try and remove it- Of course, fist of all, using the scratcherAll of them with no results. Any ideas, please?
