Delta G33 Auto Level, Bed not leveled

I have latest Marlin 1.1.3 I enabeled
delta Calibration wit fixed Z probe. I run G33 P7, everything goes well
M500, but the Bed is not leveled if I check it manually, about a millimetre
or so in the center from the corners
Am I doing something wrong or ?

Please advise
Mario

probably but with that info hard to tell

what inormation you need to solve this problem?
I'm more than happy to give any ingo you need

video and screen copy of the calibration results (G33 P3 V2); how you proceed with manual check,...

First, when I manually leveled the Bed was Delta Radius 161,42 and I manually adjusted x,y,z endsops
The bed was leveled to a certain degree.
When I run G33 Delta Radius is around 164 and Bed is not leveled.
I'v run G33 P3 V2 , here is code from Repetier:

You asked for a video , what did you have in mind?
thanks

With your manual calibration:

c:+0.00 ... center is at zero
x:-0.06 y:+0.23 z:+0.92 ... Z-tower is 1mm higher
yz:+0.98 zx:-0.40 xy:+0.35 ... point opposite the X-tower is also 1mm higher

This is not "leveled to a certain degree" but completely off

after G33

c:+0.00 ... center is at 0
x:+0.15 y:+0.05 z:+0.15 towers are a bit higher
yz:-0.05 zx:-0.07 xy:-0.09 points opposite the towers are a bit lower

What do you mean the bed is not levelled? Still much better then the manual starting point.

But you still have a big std.dev. and rather important angular corrections; that indicates something is wrong in your build and/or probe...

run a M48 X Y S in the center, at the towers and opposite the towers to test the probe repeatability at different locations (enable Z_MIN_PROBE_REPEATABILITY_TEST in Configuration.h) and check your frame (perpendicular towers to the bed; equidistant triangles,...)

By not leveled I mean when I print Bed is Convex so edges are lower than the center
so extrusion on the edges is higher than in the center.

I jus run M48 on several points and results are as follows

Iteration : 09 std dev:0.090

is a lot; I'm getting around 0.010 and printing flat. But that is due to the build accuracy.

Another thing pops into my mind; did you enable EEPROM in order to be able to store the settings? After M500 do you get "Settings Stored (453 bytes; crc -24675)"?

yes I did enable EEPROM and settings are Stored
