Have you had any luck figuring this out? I'm currently struggling with the same issue.

bed leveling not working?
Are you using the adaptive meshing that is built into RatOS or KAMP?

Printer Speed Settings for VCore 3.1 400
@blacksmithforlife 🇺🇸 Here it is. Fair warning, it is an absolute mess right now while I move various settings around and test different things. It will be cleaned up in the final version 🤣

Enclosed 400: Low corner to saddle to wave to low corner infinite loop.
@aruizramon I definitely owe you an update! So I ended up going back through everything, (gantry, belts, frame, etc.) and disassembled, reassembled and confirmed square several times. After assuring myself that everything was in fact square I did as much as I could to closely inspect the bed without removing the magnet and heater and have pretty much confirmed that is does have a slight warp (that little hump in the front of the mesh). The good news though is that all of that re-squaring/realignment did bring my mesh numbers down to the high .2 - low .3 range consistently which allowed me to finally get a .153 with the tape method! I reran it at one point and even managed to somehow get a .129! Number have been consistently around these values since then with most smaller meshes showing deviations in the .06 - .07 range.

I appreciate the advice! I'll do a quick disassemble and reassemble of the gantry today and see if that improves anything. Interestingly enough, I originally noticed that when I would shift the y-rail extrusions up and down in an attempt to level the mesh, the top of my frame would get pushed put of perfect square (only diagonally) by roughly 1/16" - 2/16" depending on how much I moved the y rails. I though that might be a problem so I ended up taking the extra idler plates (for the non-enclosed version) and used them in the front corners to ensure the frame stayed square even while moving the y-extrusions. I wonder if that could be causing the x-gantry to be put into compression and maybe I should remove them and be OK with the slight out of square on the upper frame? I'll try removing those as well as the other plates on the front two corners and see what happens.

@aruizramon I took a look and it seems to be well seated. The holes in the lightweight gantry are pre-drilled and everything lines up well

Forgot to add:
8) My X - Y printed parts and joiner plates appear to be flat and lined up. There is no binding when the gantry runs along the y axis. Printed parts are PC-CF from a member in the print-services channel and the joiner plates are carbon fiber from fabreeko.

Here is what I have I have tried/confirmed so far:
1) The frame is square. I have gone around the printer and readjusted, triple checked measurements, corners etc. My measurements diagonally, front to back and side to side are all equal. The printer was built on a quartz slab so a flat surface is not the issue either.
2) I have watched the pinned video many times and have been following it closely as my guide, unfortunately I haven't seen any. success. from this other than that one cold .190
3) I have readjusted the belt tension, checked the front gaps at the idlers and loosened the y-rails/done the x-gantry alignment procedure many times. I don't believe anything is overtightened in this area.
4) In my earlier meshes (1-50) I may have had the umbilical too tight to where it was pushing/pulling on the toolhead a bit, so I have added a bunch of slack and it no longer appears to be pushing the toolhead around at all and my numbers improved marginally.
5) I'm currently running these meshes hot with the bed at 80C and the pei sheet off. I have triple checked the magnetic sheet and I cannot see any bubbles. or bumps in the surface. I was extremely careful putting it on.
6) I have triple checked every single measurement on the electronics subframe and everything is exactly as it is supposed to be numbers wise.
7) I'm trying not to make big adjustments when moving the y-beams up and down. Usually a mechanical pencil line at most at a time. Despite this, I am still seeing wild swings from mesh to mesh.
At this point, my only though is perhaps the bed is warped? I did give it a very quick once over with my machinist squares but I'm now concerned that I should have looked more closely. Any help will be much appreciated, I'm happy to share as much additional info or photos/videos in an effort to diagnose this!
