I loved this glass bed. After so much time trying to get anything to stick to the stock ender 3 bed, this glass bed has things sticking almost TOO well.

It was fine enough for PLA, but I’ve been playing with PETG lately and it sticks a little harder.

Well today I printed the entire bed flat for a little hiking table I’m experimenting with… and this happened when I tried to get it off…

Suggestions for replacement? Should I go glass again? I don’t have bltouch so I like how flat glass is, set it and forget it. But I’ve seen those magnetic plates that allow for super easy removal but just flexing the plate, but this bed is aluminum I think. Plus that seems similar to the stock ender 3 plate that I despise.

    I put the whole apparatus in the fridge for a few hours, hoping it would just pop off.

    The edges came up clean, but the very middle was very unhappy. I had some lifting on the corners so I think there was a draft and the plate wasn’t warming equally. Hot spot in the middle trying to keep up maybe? IDK.

      Lifting on the corners, especially if this was a bed sized print, was probably due to warping. It stinks that it took out your bed, but warping probably wasn’t the cause there.

      My main printer these days is enclosed. When I print PETG on it I’ll pop the lid open because PETG doesn’t like to be too warm.

          Sorry for the delayed reply. No, too warm won’t cause warping. However, the hold side of your hot end will at best be ambient temperature. If it gets too warm you can clog your nozzle.

          My view is “if the chamber doesn’t need to be hotter why make it hotter?”.

          If you were printing ASA/ABS you want your chamber to go basically as hot as you can get it though - especially if you’re printing something big.
