Door pops open while printing
I just set up my Core One L, and it seems that during printing (I'm using ABS) the door pops open, seemingly from warping from the chamber heat. It starts opening at the top right, then eventually pops the bottom right corner open as well.
The chamber is around 51° C. when I start printing, and I'm not sure it gets much higher than that since the printer is in a chilly basement (~55°F).
When the printer is cold, the door seems to latch perfectly.
Any ideas to make the door stay closed?

I contacted support and they confirmed that the door warping a bit was the cause of it popping open. They redirected me to an alternative magnet holder which has thinner walls, and thus a stronger force to keep the door closed and it hasn't popped open since replacing the stock magnet holders.

The Core One L has two magnets in the magnet holder vs the Core One (apparently), so I had to trim the back cover down to 1.6mm in the slicer so that it sits flush with the holder.
RE: Door pops open while printing
There are magnets that hold the door in place. I don’t have the L but I routinely have my chamber approach 60° without the door warping open. The door is made from polycarbonate and shouldn’t warp. Anyway, this is the first I’ve heard of this. I would contact support over chat. Until then, tape?

It's good to know that yours doesn't warp. I have been just using tape.
I'll take some pics and contact support, thanks for the reply
