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.
Wouldn’t the simplest explanation be that the left side of the bed should be lowered a little?
It is already at the lowest it can be but I’ll try raising the right side again
I’d suggest loosening all the bed screws as much as is practical and then redoing the mesh. That way you’ve got lots of room to lower high spots.
If the tilt is too extreme, you might also be dealing with a sagging gantry. I’m not familiar with your printer model so I don’t know how likely that is or how you’d go about fixing it though I’m afraid.
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
You mention that you used an indicator? Is it applying force? Does your bed or you X axis deflect?
Am I stupid? Tried leveling by hand and now I’m getting these weird results again as if the glass bed is higher in some spots…

I’ve never gotten these values to be close to each other (less than 0.5 difference)
edit: I don’t get it… the glass bed is perfectly level by itself. How can the printer read high spots on it?!
