Z- TILT doesnt work correctly
I have a very weird problem with my heightmap. I seem top have a relatively flat bed with minor bending in the y-axis. The problem im facing is that the whole bed seems to be tilted to the back of the printer.
How should i fix this issue?

I would like to utilize this bed as good as possible. It seems that an easy fix would be that the stepper near the back panel would go up a little bit to correct it.

I would double check your Y extrusions are really perpendicular to the vertical frame extrusions. 0.3mm isnt much so you need to be accurate. If thats indeed the issue then you can raise that side of the extrusions by perhaps 0.5mm. Its a bit trial and error.
did you do anything to correvt this ?
its possible that i'm in your shoes rn
I haven't gotten around to trying out all the options yet. My best guess is that the lead screw decupler is not working quite right. During assembly, I noticed that two of the three leadscrew decuplers are smooth. The third of the three leadscrew decuplers was binding (most likely due to a manufacturing or quality assurance error). I installed this difficult to move leadscrew decupler at the rear Z position. My guess is that the firmware is trying to level the bed but the movement is not getting there because the bed is not moving at these fine accuracies due to the binding lead screw decupler. I will try to remove the lead screw decupler and sand down the individual functional surfaces a little so that this lead screw decupler also moves smoothly. I will then report any news.
I placed the bed on a very flat surface (granite worktop from the kitchen) and looked for deviations in the flatness of the bed using a flashlight and the light test. There was no light gap to be seen here. I therefore assume that my bed has no problem.
that makes sense
i think i might be facing something similar
will have to disassemble and check
are your z-tilt coordinates outside of your mesh coordinates? I had a similar tilt, only the entire left was down and this was caused by a purge line stuck between the palte and the magnet. the z-tilt coordinates included this section, but the mesh did not.
Unfortunately, this does not solve the problem. Due to the fact that my lead screw decupler is jammed, it often happens that Z-Tilt is "out of range" and therefore aborts.
