Sometimes PCB klicky probe is unreliable

Yes, i just found out that the taco moves with the spring sheet. Root cause not yet identified…

Said. Done!
So upgraded to Cartographer USB, works like a charm. But i guess i found out now that i have some other problem, trying to figure out but kind of helpless now. Doing a scan of my bed, without print plate comes out quite well (my guess), hightmap shows a range of 0.109mm.

But when i attach my spring sheet, tried all 3 i have, i get results i do not understand. -> Do i need a new magnet? Or are all my spring sheets garbage? Or is this normal and i am good to go.
Got 2 Times perfect first layer, but now suddenly again disturbing results (5 patches, some are perfect, some are squished into the flexplate) and that even while using bedmesh > that does not make sense at all to me.

It is a juggling act... I'm getting weird prints on certain sections of my bed, now that I'm using CNC Z-Idlers. Gonna have to wiggle the printer a bit and figure out what needs fixing.

for anyone dropping by, the main issue was loose closed z-belts on my voron. all measures i did starting with CNC toolhead, MGN12, Carto, belt tension (z-belts), ne idlers, twisted x/y comp, thermal compensation could not solve it. Root cause why they were loose? i don't know yet, i have some ideas but it will take time to confirm. till then, in the video you see before and after (while i do not know if after is too tight, it works like a charm)
