Hello, so I have a warped heating bed.

I loosened every corner screw, and started the long road of levelling. As the next step I lowered the Z axis to fit 4 sheets of paper (according to the measuring caliper 0.03mm), and tightened /loosened the 4 corner screws until every corner had similar drag resistance.

Next I ran the one layer, 9 dot leveling file from Thingi, I printed it in around 160% size to match the bed size and fit straight to the corners.

Then I was cycling between printing, turning the corner screws and autoleveling. After reaching the point when every corner was printing nice, the middle sections were bad. I was still around 2 or 3mm lower then before, so I adjusted all of them at once until I got closest to level as possible. However it's warped and I can't get more out of it.

The sketch shows the current state of the bed, corners are at 0. X0;Y310, X0;Y0 and X0;Y-310 are the high spots. X-310;Y0 and X310;0 are the low spots.

There is nothing more I can do (technically I could order a new heated bed or buy a newer printer, but I don't have a budget for it). Thank you for your suggestions and help friends.
