Thermistor 2000C

[Stephen6309]

@ivan_sk Usually caused by: Bad conection, Bad wiring, Bad thermister. Use a multimeter to check the resistance.

@stephen6309

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

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.

@ivan_sk please run the following commands with no extra parameters, from the DWC prompt (or from USB if you don't yet have DWC running) and report the responses:

M308 S1
M308 S2

They should report the type of the last error seen when reading the thermistors.

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

@ivan_sk Could you please unplug both thermistors from the Duet and measure the resistance between the two (mostly) black lines, then, between the red lines? Maybe there's some connection?

[Ivan_sk]

@infiniteloop

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

Sorry, I meant to measure the cabling, not the board …

Thanks. Do you get that response when nothing is connected to any of the three TEMP inputs? If so, then you board is faulty and you should submit a warranty claim to warranty@duet3d.com.

@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.

Thanks. I just wanted to exclude common ground in head or lines.

@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) .

[dc42]

@ivan_sk if there's no other damage, we will still accept your warranty claim.

Please accept my deepest thanks .
