Finally got my 2.5 upgrade, bed level question

Assembly went great, I attempted to do a time lapse, but forgot to lower the camera quality and filled the card before I was half done. ( ), still fun though, I like that you can see the candy supply dwindle as I work.

I have a question about bed level. Got my live z dialed in pretty good. My test square is smooth and solid, and measures 0.19-0.21. Overall happy with it. I then got the bed level visualizer plugin for octoprint. After configuring it and generating a mesh I got a result with a right side that seemed way high. I played with the bed correction and it made changed some numbers, but not a ton. I loosened the bolts for the z axis bracket and re-seated and re-tightened and it improved the back right corner, but front right is still off.

I have attached the png of the plot it generates. Currently the bed correction settings are zeroed out. Will the auto leveling compensate for this? Or should I mess with the correction settings? My instinct is to put positive adjustments into the front and right fields, is that the right move?

thats exactly what the 9 point bed leveling is for.
Of course it compensates that difference!

If you print something and observe the Z steppers, you will see them sightly turn around.

So dont worry too much! 😉

Thanks I had a feeling that it was still good (and prints have been turning out ok). I thought I read somewhere that the auto-leveling only worked to a point and you could use the bed correct to bring it back in range.

Re: Finally got my 2.5 upgrade, bed level question

it's worth trying to make it physically as flat as possible... a print the size of the bed would follow the beds curvature so the bottom of the print would be warped the same way.... so physical flatness is always best. 9 point's isn't that much and don't work as great as you think. 16 would be best. (4x4 grid) if you got the bed flat, you could just turn it off....so no probing every print.
