Hello. I am wondering if anyone has tips or tricks to prevent a glass surface on a heated bed from warping?
The problem is, my warp is happening upwards, where the center is higher than the four corners.
I drew a red curve to make the bend more apparent, as it's tricky to capture with a camera.
I've looked at several Youtube videos, and many say to lay masking or painter's tape down, but that's usually for warps happening in the center of the heated platform that go downward, forming a pit. My bending is in the opposite direction.
Does removing the glass bed from the heating platform, with the print on it, to let it cool down cause the warping? Should I let the print cool down while staying on the heated platform? Would that make a difference? The prints will automatically separate from the glass once the glass itself has completely cooled. I thought it would do it faster if I remove the glass from the bed and let it sit on the dining room counter. I'm still an amateur as I've only been printing for 3 years.
This bending happened on my Anycubic Mega X, the same size as the Creality CR-10. But I owned a CR-10 for 2 years and this did not happen. Since day 1 of receiving my Anycubic Mega X, I had to perform at least 5 leveling tests, since the prints always came out inconsistent, especially on the 1st layer. Now the bending has become apparent.
I received my Mega X for my birthday a couple days ago via Amazon, so they're letting me do an exchange.
But it's guaranteed that this could happen on my newly exchanged version once I receive it. How can I prevent this kind of bending from happening?
