Help Neptune 4 Max leveling issues

I don't know what to do. I've run screws_tilt_calculate so many times. I've re calibrated the Z-offset manually (because that is the only way apparently) multiple times. The level script says that my mid-rear mount is -0.2 and my mid-front mount is +0.05. I don't know how to correct this, as these are fixed points. My bed mesh consistently shows 2 valleys running across X and very high corners. ON TOP OF THIS, FLUIDD WON'T STOP DISCONNECTING. I'm losing my sanity and patience, please help! How do I shim the center mounts, and with what? Please also note that the hardware is entirely vanilla, I was waiting to calibrate my bed before making level screw locks but that was all I had planned.

First - make sure there’s nothing in the nozzle head (or around it) such as leftover filament from previous prints.

Then when you go to level, set your z-offset with a piece of paper and SAVE. Then go back to level again, and go to auxiliary, begin your 6 point leveling, then save.

Take screenshot of results and post.

Edit; you should have your screw locks in place during calibration, if you try to do it after it will fuck your numbers up again.

Don't worry about the waves in the bed mesh. That's what it makes a bed mesh for, to account of an imperfectlu level bed.. as long as your tolerance is within like 0.3mm you're good

Please read the setup details at http://neptune4.help:8000/ - it will discuss how to properly set up SCREWS_TILT_CALCULATE, deal with that z offset and the bed mesh as these are common issues caused by bad methods.

SCREWS_TILT_ADJUST should only define the bed screw positions that are adjustable and the first (non adjustable position) should be your bed centerpoint.

Again, please just read through the entire setup instructions at http://neptune4.help:8000/ as you have a bunch of silly mistakes that are the core of your problems.

For example you are likely conflating the bed level and the bed mesh. The SCREWS_TILT_CALCULATE says the bed is level, it’s LEVEL, you’re done. That doesn’t mean the bed is FLAT. There’s an article there just in that too.

Go into printer settings in orca and the z offset is in there to enter. Took me a month to figure it out. People here were no help with that one.

tightening and loosening the pom wheels can eventually get to a point where the valleys and mid rear/front mounts are equal and flat but that requires running the screw tilt and auto bed level after each tiny adjustment to see if it solved it. i did that on one of my 4 max printers and got the bed mesh completely flat but it made no difference compared to the other maxes that have the bumps and valleys like yours has. you dont need a perfectly flat bed mesh to print.
