Ender 3 V2 Neo z offset bed levelling

Ender Series Creality Ender-3 V2

So Ive always had issues with bed levelling / first layer nozzle clogs etc.

Currently I am about at a 10% failure rate on prints due to this issue. Not bad considering Im not using an enclosure and my filament is stored rather haphazardly. Please note most of my prints fail at first layer or bed adhesion issues so soon as I get the first few layers Im in the clear. this is why I am leaning it not being an environmental or material issue.

Currently running MRISOC firmware and utilizing the tramming wizard and 91 point ABL

Tonight I checked my ABL just for funzies and was off a bit and did tramming and rechecked again for fun… Im usually a check and recheck if nothing is making sense

Anyways my usual manual bed tramming / levelling method is the following

set z offset to zero
auto home
check the corners and adjust them until a business card takes at least 2 fingers to move with deliberate force
when corners are adjusted I go to center and use z offset to ensure center is the same and it usually has worked

You are doing the same thing as I do with my Ender 5 plus, tram the corners, set the Z offset in the centre. Run an autolevel mesh. What I then do is run a print with a wide skirt, whilst that is printing I adjust the Z-offset so that the nozzle is at the correct level, normally needs 0.05-0.1mm sometimes a little more. Takes a little practice but all my printers need a little extra Z-offset to be perfect. I turn off autolevelling/calibration once it is set otherwise it resets itself and you have to start again.
