@T3P3Tony I think I've read your article about the Kraken when I first looked into buying one.
So no mesh bed compensation for me then.
Thanks again for the help.

RE: PID Tuning Edge temperature AC Bed Heater
p0.9 did the Job
Heater 0 model: gain 159.6, time constant 1084.6, dead time 50.7, max PWM 0.90, calibration voltage 24.1, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P23.9, I0.102, D849.4
Computed PID parameters for load change: P
16:03:01Auto tune heater 0 completed in 1388 sec
Use M307 H0 to see the result, or M500 to save the result in config-override.g
15:46:21Auto tune phase 3, peak temperature was 64.5
15:45:22Auto tune phase 2, heater off
15:39:58Auto tune phase 1, heater on

How to remove Sensor not ready error
I want setup a Dummy heater so I Put this in to Config.g:
M308 S5 P"duex.e4temp" Y"thermistor" T100000 B4138 ; configure sensor 5 as thermistor on pin duex.e4temp M950 H5 C"e6heat" T5 ; create Dummy heater and map it to sensor 4
I Tested Sensor 5 using M308 S5 and got this
M308 S5 Sensor 5 type Thermistor using pin (e4temp,duex.e4temp,exp.thermistor5,exp.37), reading 40.5, last error: sensor not ready, T:100000.0 B:4138.0 C:0.00e+0 R:4700.0 L:0 H:0
Now I want to know how I remove This Error
RE: Dual Thermistor setup
@dc42 I have added this to my config.g but the temperature of the dummy heater is not showing up neither in the web control nor thru M105
M308 S5 P"duex.e4temp" Y"thermistor" T100000 B4138 ; configure sensor 5 as thermistor on pin duex.e4temp
M950 H5 C"e6heat" T5 ; create Dummy heater and map it to sensor 4
RE: Mesh bed compensation with E3D Kraken
The bed should be mostly Flat I´m using a machined Aluminium Plate with 4 Leadscrews (Yes, I know it´s over constraint but i didn´t when I ordered it) and the true Z alignment enabled (https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors)
RE: Dual Thermistor setup
I haven't tried it, but I think you could do it with RRF3. Configure the heater and sensor 1 as normal. Configure a dummy heater using sensor 2. Something like this:
M308 S0 <sensor 0 parameters>
M308 S1 <sensor 1 parameters>
M950 H0 C"bedheat" T0 ; the real bed heater
M950 H1 C"e6heat" T1 ; the dummy bed heater
This won't work if T2 reaches X before T1 reaches X+10.
Since I had that accident were my Hotend melted(https://forum.duet3d.com/topic/13380/why-did-my-printer-melt), I want to get this right:
Does e6heat = !duex.e6heat
or e6heat = !duex.e5heat
or neither of the above?
