If the bands are closer together at the bottom because the bottom layers are bigger, what causes them to get closer again further up the columns?

There has been a video posted on YouTube recently showing heated bed PCB flexing on a Mendel90. It looks like the poster was getting 0.05mm of flex at 70C with bang-bang heating. I have asked if he can re-test with PID and post his results.

It's not enough.Quote

I had a very similar problem to you. Here are things to try:
- Make sure there are no drafts in the vicinity of the printer
- Try putting the clips as close to the edges/corners as you possibly can
- Make sure you always have the corrugated cardboard under the bed
After doing all these things I got really good prints.

When using bang-bang you will always get some movement - the only thing you can do is minimise the effect. The suggestions I mentioned for me greatly reduced the movement of the build plate. Everyone's mileage will vary.Quote

It's not enough.
See video bang bang
When on(click 0:07) - you see light in gap between caliper and X smooth rod
When off (click 0:23)- no gap.
As I understand - when on, bed becomes lower.
