With my Anet ET4, I also received a plastic sticker. I assume this should be stuck onto glass, not to a metal bed. If I understand this right, when sticking this to glass, I will damage the glass and I cannot use the glass as a bed in the future if I change my mind and decide to experiment with glass again.
Isn't better to buy another glass and stick the plastic there? Or is better to buy some completely different sticker? I have many problems with adhesion on Anet ET4, so looking for options. Any ideas?
