I used a precise angle and a long metal ruler to check the diagonals, but I think an angle is enough when already assembled. About in the middle of the video the dude explains how to correct a already assembled frame.
I got my vcore 400 with this video from .5mm deviation to ~.1
Well i hope i will be able to do the same with the 500, thank you for the help fritz !

I actually wanted to open a new thread but I think it makes more sense to join in here so as not to unnecessarily clutter the Discord with the same topics. I have a similar problem, but the frame is okay and the bed has gotten worse over the course of about a year. Full enclosure 500 mm and runs almost exclusively with ABS and ASA. Initial bedmesch was in the range of 0.15-0.22. Now it is basically no longer usable for large parts. Magnetic plate thought I had come loose, everything was okay and initial measurements where the aluminum of the bed was bare could confirm that the bed really looks like that. Which is a disaster. Is there anything known there that something like this happens to the aluminum bed, which is actually milled? Thanks.

This is probably your x-axis. Especially in a heated chamber it likes to warp. You have to loosen the x rail and retighten it. This is also explained in the youtube video.

I'll check it tomorrow with a straight edge and feeler gauge. On the measuring machine I actually picked out the side that had a little tension downwards on the top in order to compensate for exactly that. The printer is in my company and is not a private device. I'll take a look at the cold and warm because the bed is almost as bad cold. But thanks in advance for the approach.
actually you are supposed to start new posts, so that posts don't go on different tangents with various people's specific issues
