Print bed "warped" towards one side

Hello forum,

during a print with some support I discovered that my printbed seems to be slightly higher towards to front right corner.
When support was printed, spaces between the lines vanished, see attached picture.

I thought this was supposed to be compensated by the pinda probe? Or is this a misunderstanding on my side?
How should I resolve/debug this?

Any advice welcome.

Hi Andreas.

mesh bed levelling does it's best but miracles need a little help...

you could try putting a couple of sheets of paper between the appropriate bed spacer and the Y carriage... to mechanically adjust this corner
or you could adjust the bed level correction settings in the calibration menu,
or you could look at the Hyperfine bed levelling thread...

Regards Joan

First make sure this is repeatable - do you get the same affect regardless of what you are printing?

look for contamination on the bed or the sheet - clean it!

perform the G80, G81 investigation to see what values you are looking at.

if you have consistently one corner off imo the best way to fix this is to move one end of one x axis rod up or down a little bit. A single bad corner is a clue that the two rods are not parallel to each other. Even if a bed were perfectly flat if it is driven along two rods that are not parallel it will show a twist shape.

I am lucky to have a granite surface and height gage at work and I first discovered the out of parallel rods there. I checked the printer there just out of curiosity.
