Hi, just a quick update. I did a test with water and ice, the temperature drop at 14°C.
Anyway, I think with the actual smd thermistor it will work.
When my duet2wifi wiring will be finished I'll be able to test it in real conditions.
I made a change on configuration file buy editing the B value to match the datasheet specification (4100).
Thanks everyone for your help.
Hi,
See this link, I suppose this is why there is +5V.
I ran some test. So I plug the sensor to the duet with only 2 wires. There are connected to Signal and Gnd on the heated bed. The DuetControl app give me 25°C room temperature, not bad. I warmed up the thermistor with a blowdryer, temperature ingrease to 40°C. I currently doing a test with melting ice in a bag to get close to 0°C.
Hi,
Thanks for sharing.
I currently trying to keep a maximum of part, but it doesn't mean that I wont change it later.

Thanks, Yeah you right but now when I measure it, I got 10kohm... Anyway, I'm gonna plug it back and check on WebControle the value.
Are we agree that this type of thermistor is compatible with Duet2Wifi ?
@Veti
Good, thanks for the information, good idea to check on Marlin. So we can see the sensor on the picture n°2.
I just measure 10kOhm. Don't why I got a 100kOhm when I first checked...But according to the spec i should read 100 000ohm... I'm gonna do futher research. Thanks for your help.

Hi, I don't see any thermocouple. When I bought the machine, there was some missing part...maybe they remove it before but not sure
Hi, I recently bought a Raise3D N2 and decided to install a Duet2Wifi.
I have a question about the heated bed thermistor on Raise3D.
Here is a diagram I did by measuring the resistor installed on the bed.
The bed provide a 3 wires connection : Signal, +5V, GND.
On Duet Wifi, only 2 wires are necessary.
Can I plug the Signal and GND wires of Raise3D Heated Bed, directly on The Duet Wifi ? Are am I missing something ?
Thanks for your help.
