Is this beyond the pale? Recently got a Neptune 3 pro and have been having issues. Anyone have some tips? Is this resolvable? Can a bed for these be replaced?
I uncommented the Gcode line to use this matrix now which I didn't before. But still having a lot on inconsistencies.
I recently picked up a Neptune 3 Pro as my first printer. Went through the leveling and saw similar to you. Even after the Z height calibration.. there are issues.
A print with a small footprint works fine, but when something covers most of the x axis I would find that the left side of the bed would print well and the right side of the bed would have gaps in the first layer.
Installed klipper, tried out it's bed mesh calibration and increased the testing points to 12x12... Still similar issue. I'll be sending it back.
Oh man. Even with uncommenting the auto bed level in Gcode? I bought this used (but in impeccable condition) so I don't think I can return. Guess I'll have to keep messing with things forever!
