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.

How do you keep the plate flat to the bed without magnetics?

[–] PerogiBoi@lemmy.ca 3 points 3 days ago (1 children)

It’s magnetic so it snaps on and off. The magnets are quite strong.

I googled it, you put down a magnetic sheet first. Sweet, I ordered one

Mine has a magnetic layer that adheres to the existing bed. Then the PEI plat sticks to that.

Awesome! I ordered one, I'll give it a try

FYI, I had to compensate on the bed heater to compensate for the extra mass and thickness. I don't remember how much, but not a ton. Plus a little longer of a wait to let the heat saturate before starting the print.

Can't be much worse than a big hunk of glass?

[–] talentedkiwi@sh.itjust.works 2 points 3 days ago

Nope, but a big hunk of metal (magnet) plate
