I got tired of the paper method and adjusting the screws by the auto-leveling results as I could never get them to be consistent. Now I used mechanical level indicator and got these consistent values indicating that the bed is tilted to the right/left?
To my suprise it can actually print something like this but what would cause these values? My suspicion is that the Z axis is sagging but I would like to get some opinions before completely reassembling the printer.
Is your z axis driven by a single leadscrew? Google x axis sag as I think this is what you are facing.
If you have dual leadscrews you just fix one and raise the other to tram the x axis to the bed.
If you have one leadscrew… Google x axis sag as I don’t have much experience there
