Problem with temperature sensor mark 2000°

[wilriker]

@kyll We need some more information to answer:

• What type of sensor (mentioning daughterboard I would assume PT100 but please confirm that)
• RRF version (M115)
• Have you configured the sensor? (M305 for RRF 2.x or M308 for RRF 3) If so please post the condiguration

[kyll]

The sensor is this one :https://e3d-online.com/pt100-temperature-sensor and i'v tried to change the config file by typing M305 P1 X200 at the place of the heater

[Veti]

did you verify the resistance of the pt100 sensor?

did you connect it to the correct terminal?

just checking. you do have the duet daughterboard and not the e3d daughterboard?

[Veti]

when you enter M305 P1 X201 in the console(not the config) does it also show 2000?

[kyll]

[Veti]

that means it cant talk to the dauthterboard.

did you connect it the correct way round?

[kyll]

[Veti]

that is the wrong way.

compare the documentation
https://duet3d.dozuki.com/Wiki/Connecting_PT100_temperature_sensors

the spacer should line up

[kyll]

Ok but right now the screen show -0.2°

[Veti]

@kyll said in Problem with temperature sensor mark 2000°:

-0.2°

thats the 100 ohm resistor. now switch the channel

On it's working thank you so much
