@droftarts Good Morning....
I already put the sensors with 4 wired conexion and i have the error again , i don´t know what is happend .......
The pt100 sensors read 2000 ºC when the heater is on every 10 or 15 seconds , is no always the same time , do u think is a interference problem???? , do u think a ferrita core is a possible solution??????
Thanks
Hello again.... 
I revised my wiring conexions and fixed it , but i have problems again , i remplaced my 307 lines with the parameters of the tunning but , when i try to use the heaters I have a notification "Header 2 fault: failed to read sensor: sensor shot to other wiring" , i resised wiring 2 or 3 times and i think was Ok, Do you think the cause could be the length of the cables or it could be something else??????
parameters of M307
M307 H1 R0.337 K0.402:0.000 D11.85 E1.35 B0
M307 H2 R0.238 K0.228:0.000 D8.78 E1.35 B0
Thanks
Ok... Thank You very much....
should i remove all this lines from my config.g???
M308 S1 P"spi.cs0" Y"rtd-max31865" ; configure sensor 1 as PT100 on pin spi.cs0
M950 H1 C"out1" T1 ; create nozzle heater output on !out1 and map it to sensor 1
M307 H1 B0 S1.00 V24.0 ; disable bang-bang mode for heater and set PWM limit
M303 H1 P1 S40 ; Heater 1 power 100% Temp limit 40º
M143 H1 P0 S50 A2 ; set temperature limit for heater 1 to 50C
M308 S2 P"spi.cs1" Y"rtd-max31865" ; configure sensor 2 as PT100 on pin spi.cs1

M303 H2 P1 S40 ; Heater 2 power 100% Temp limit 40º
M143 H2 P0 S50 A2 ; set temperature limit for heater 2 to 50C
Ok, I think i must remove this line from mi config.g and execute it like a comand in mi control panel , correct???
is this the execute form i must tu use ????
M303 H1 P1 S40
Thank you very much.....
I use this line in my config.g...
M303 H1 P1 S40 ; Heater 1 power 100% Temp limit 40º
But i don´t know this is correct or not.....

No... I don´t know how to use M303 comand.....
Good morning:
I would need help to configure the heaters on my Duet 3 Mainboard 6HC, I have a print head with a heater and a material dispenser that also has a heater, the temperature sensors are PT100 type. I have a max31865 board for the PT 100 sensors (RTD1 and RTD2), which are 2, the temperatures are displayed well on the screen but it seems that it is not able to control the temperature of the heaters with the sensors, it does not relate them well.
I manage to heat the head and the dispenser but not control the temperature, even though they heat up and up ...., they exceed the limit that I set in the software,
my config.g ....

Thanks
@dc42 Ummm I think i going to buy others endstops ... Do you know any model that works well and is easy to configure?
Thanks for all
@imartinez ....and this label is from the igus endstop...
https://www.igus.com/search?q= INI-AB-I-025-A-AA
Thanks again...
@droftarts Don´t work... i can´t home the axis because the endstops don`t works .....
Thanks for help me...
Good Morning....
I have a Duet 3 MB 6HC in a cartesian printer and i can´t connect the endstops of igus (normaly closed) , the driver can not go home the axis .... Can you help me , please???
Thanks
