Mesh Bed looks like this dualWave... no matter what

And the best of it... it does nothing... my printhead collides on the areas mapped green, or the filament gets round on the other areas. so I can't print anything...
I updated to duet3d (2.05) and webcontrol 3.11...
After G32 --> delta calibration with 16 points and factor9... I generated this:
M665 L397.303:397.303:397.303 R156.932 H539.918 B175.0 X-0.014 Y-0.248 Z0.000 M666 X-0.503 Y0.886 Z-0.383 A0.77 B-0.18
I do run a G28 (home with Z axis uses as probe), so I have after homing the probing of BL-touch to exactly have my Z height, which is really Z=0 with a piece of paper between.
Then I save it with M500. Reboot the machine and load the config-override.g with all values stated above.
Now I create the Hightmap which looks like this:
The fully thing about this is, I totally rebuild the machine with all bearings and belts, because I thought there would be a backlash problem... but it was not... after rebuild, the map looks even wavier than before.
If I load the map with M29 S1. it seems not doing anything since the head crashes on the heights and builds up round filament because of too much distance and to less extrusion.
HELP, or at least one little hint what else to try...
Thanks to all who read this...

have a look at this
did you start out with 9 factor? or did you adjust to it?
where is your probe? if its offset that could be a problem if you have effector tilt.
post your config.

I looked at this Calibration Error page, found a single wave with towers moved out so I rebuild the machine ... yes this site was responsible for me rebuilding the entire machine, but really it did not change anything, but I was happy to resolve a couple of problems like loose pulleys on steppers and loosened belts on the carriages. (But remember, I never actually did a productive print at all, only test prints. The machine never evolved to a productive environment... highly experimental only... maybe 50h of test printing)
The mesh looked much more like a cliffy waved surface. After the rebuild it looks really homogeneously nice double wavy.
I rewrote the config removed all loads and reloads of meshes in the config and from the homing, so if the machine starts up only delta calibration from the config-override is loaded.
I did I think all factors from 6 to nine... nothing really change something.
Yes I have a probe offset, but how does this come into play if I do a mesh?
Even with a tilt, isn'i it supposed it to be constant? on all points, since the Effector does not rotate?
I went through all config tutorials for delta and the result is only a beautiful double wave, which does not compensate even if I load the mesh...
I used this for creating the bed.g: http://escher3d.com/pages/wizards/wizardbed.php

M350 X256 Y256 Z256 I1 ; Configure microstepping with interpolation
First this is not supported on a duet wifi.
Second this is a bad idea on a delta. it will overload the cpu.
unless you have a very specific reason you should go with x16 with interpolation.
M305 P1 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 1
unrelated, but your thermistor setting is wrong.
dc42 calls that "crinkle crisp"
on my delta i also had problems with my first layer when using a probe that was offset.
in the end i went with this https://www.aliexpress.com/item/32838312776.html and it works very well.
@duetino if you suspect errors due to the offset probe, try running a calibration and then mesh compensation with M558 P0. Yes, that’s manual probe, but measuring from the nozzle tip will give an accurate reading, especially if your nozzle hangs down a long way below your effector. It’ll take a while, but you’ll see the true results ‘at the nozzle‘. Don’t forget to set G31 offsets to 0.
Offset probes on deltas are just not great. Calibrating deltas is hard enough, adding an extra variable is unwanted. Get some kind of piezo or contact probe.
