On achieving a perfect level

I did actually. But the results weren’t perfect. With the innermost screws it tended to “curl down” at the edges in my case, with the outer screws it bulged a bit at the center.

What I’ve been doing now was to place it on the bed with all screws loose. Heat the bed to standard printing temps and then tighten the screws (not hard, just minimal so it won’t move up or down) starting at the center and then work my way from the inside to the outside.

After looking at the bed level I could then tighten those screws a bit more on those locations where the bed was a bit high. (using the bed level visualizer plugin of octoprint).

But right now I’m on another mission to improve this further: Idea for quick switch bed: feedback requested. I’m thinking that if the printbed is on top of a completely flat surface and supported equally at every the curling up/down of the bed would be a lot less and that leaving some play by not tightening all screws might be better.

But those are just my (basic) experiments, your mileage might vary.
