Re: First layer calibration problem

I am having exactly the same problem. Managed to make it a bit more even after playing with LCD Menu - Calibration ​- Bed level correction. I still fail to comprehend what for is the Mesh bed leveling if it can't compensate for the deviations.

Re: First layer calibration problem

Exactly the same issues for me. Autoleveling doesn't seem to work. How can I read the calibration data?

The same for me.
Very interesting is the following fact: measured with a steel ruler, the right side of the steel sheet (printbed) declines about 0,5mm.
I hope this is right verbalized.
This means the mesh-bed-levelling must be working somehow.
But i get the same result.
The right side of the first layer calibration is a bit more squeezed than the left side.

Re: First layer calibration problem

I'm curious if some of this is caused by slight variance in the X axis or Y axis level. Like for Y axis, maybe the frame is just slightly out of whack. For X axis maybe try re-doing the step where you level it just a hair above the build plate (with steel sheet removed) prior to adjusting the height of the pinda probe.

Without knowing exactly how the auto-level algorithm works, I just wonder if it relies on these two things being near perfect.

Just my thoughts, I'm probably wrong.

A bit strange is that (at my MK3) the area of the printbed on the right get´s the better result.
Even though it is a bit lower (or a bit more away from the nozzle) than the left side.
I`m talking about max. three tenth of a mm.

Re: First layer calibration problem

Having the same problem, i noticed with a larger print the right side(far side of origin?) Is not sticking or narrower than the left side
