Please accept my deepest thanks .

@dc42

Thank you for feedback. This is report without any temp inputs connected.
Iam afraid of submit a warranty claim because I accidentally broke part of small plastic pin as you can see in previous photo of board (temp_0 pin) .

@infiniteloop
oh sry, but that are two separated thermistors. I already measured them separately. There are no connection between black - black and red - red. Its genuine e3d thermistor with cable.

@infiniteloop

Red - Red. 6,9k Ohm
Black - Black. 6,9k Ohm

@phaedrux said in Thermistor 2000C:

If you send M98 P"config.g" do you get any errors?

2000c very likely means the thermistor isn't actually making a connection to the board, so triple check the wiring.

Heres report. Is there any way how to check if temp_0 to temp_2 works? Can I measure them or something?

@stephen6309

what resistance should I check?
Thermistor is 100k with multimeter. Thermistor with extended cable is 100k, is connected to temp2 / temp 1 port.

Hello Gentlemen,

I would like to ask you for help. I purchased my first Duet 3 mini 5+ wifi and have problem with thermistors (E3D blue one 100k). I have all reading on them 2000C no matter if they are plugged or not. I'm trying to fix this for more than 2 weeks . Any suggestions ?

Hereby some info from machine:
Config
; Heaters
M308 S0 P"temp1" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin temp1
M950 H0 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"temp2" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp2
M950 H1 C"out1" T1 ; create nozzle heater output on out1 and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S280 ; set temperature limit for heater 1 to 280C

; Tools
M563 P0 D0 H1 F0 ; define tool 0
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0 ; set initial tool 0 active and standby temperatures to 0C
