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.
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!
Not having leveling screws sucks, but check how Z gantry is installed. It might be not perpendicular, also left and right Z rods can be used to level your X. There is also option to shim bed/frame (think placing washer or aluminium foil between two parts to increase height) Id try to get it <1 mm, but I believe ABL should be able to compensate even your numbers anyway.
Btw are you sure your ABL is working? Do you see Z axis moving while printing single layer?
