Revision to Connecting thermistors or PT1000 temperature sensors

David Crocker

Parameter B3950 in the above example means that the thermistor B value over the temperature range of interest is 3950.
 
The R parameter is the value (in ohms) of the series resistor on the controller electronics, which is always 4700 ohms onelectronics. You do not need to specify this value unless you are using a Duet WiFi and06 or a DueX4 expansion board. If you do specify it, the correct value is:

* Duet 2 WiFi,
Duet 0.8.5 controllers, as well as Duex22 Ethernet, DueX2 and Duex5DueX5 expansion boards - but see the note further down this page. It defaults toboards, and Duet 085: 4700 in the

Duet WiFi firmware, and 1000 in RepRapFirmware for the2 Maestro: 2200
*
Duet 0.8.5 and 0.6. The06: older generation Duex4 expansion boards have a series resistor value of 1000.1000, newer boards 4700
* DueX4 version 0.2: 1000
* DueX4 version 0.2a: older boards 1000, newer boards 4700

For the E0 thermistor, the command is similar except that P0 is replace by P1, for example:
