M308 S0 P"bedtemp" Y"thermistor" T100000 B4700 ; configure sensor 0 as thermistor on pin bedtemp
this is wrong. you need to find the correct beta value.
G31 P500 X-40 Y-10 Z0 ; set Z probe trigger value, offset and trigger height
you have not put in your actual value. after changing this, you need to restart the duet.

@Veti Hi, thank you for the reply.
In the first point you mention, how do i determine the beta value?In the second point, yes, i know. I have allready stablish "z" with the value the DWC determinate after G30 S-. In fact, i´ve give it different vlues, seen the first time, it stys 0,40 above the bed. I tried to low the nozzle a litle, increasing the "Z" value, but it stays allways at 0,40... regardless the value i have on "Z"!
-
@Hélder-Rocha "G30 S-1"
-
so modify the G31 in the config and test the homing.
-
@Veti i have done it several times...i´ve defined Z to 0.23, the first value obtained with G30 S-1. After restart the duet, and do homing, the zozzle stoped 0,40 mm above the bed, but the Z value on the DWC is 0,23mm!
After that, i encreased the Z value 10 by 10 to check if the nozzle wold get closer to the bed! But nothing, it stays at 0,40mm all the times. -
the config you see, i have "Z" value at "0", because i put it to "0" before a leave my printer last night. I intent to restart the configuration today.

your original value was far bigger

@Veti it was not workig correctly either with the old firmware. After update the firmware, i already tried with 1.60 and it stops at 0,40mm.... the question is: Dont matter the value i define in G31 "Z", the probe will allways stop at 0,40 mm plus 5mm(because G1 Z5 F100 ) above the bed. If i down the nozzle by 5mm, in the DWC will show the "Z" Value defined on G31, but when i go measure with the wedge feeler, it is 0,40mm above the bed. Allways!

0,40
do you use , or . ?
since you never posted the config with a value in it its hard to tell -
@Veti yes... is with "."
-
send the G31 command to verify that your offset is put in correctly

When you click that button in the post creation window it adds a section between three dots above and below. Put your code in the middle where it says code_text.
