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.
What seems to be the issue? If you got those mesh numbers using a probe, it just indicates that your bed is unlevel. You can home it, then disable the steppers to move the hotend around, and do the paper test. If you haven't leveled your bed before then you can google the paper bed-leveling test.
I say this because it seems like your bed is slanted downwards on the bottom-left corner (and/or slanted upwards on the front right corner). No offense if you do know how to level your bed though, if it's some other sort of issue do let me know.
Oh yeah I mean it's definitely not level. The 3 pro doesn't seem to have a way to manually level it. There are eccentric nuts which I have tightened, and that did stop the bed from rocking. But I think this is the "natural" lay of the bed. It seems like the disparity is vast
Wasn't sure if there was something that I'm not seeing on how to fix this on this particular device.
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!
