I got the value from the reprap configurator calculator and measuring the thermistor resistance at different temperatures. I dont have the network side of my setup finished yet so i dont have access to the web interface however in Pronterface Ext2 reads a constant 0C.

Just finished modifying my printer to run on a Duet Ethernet and through Repetier host the second extruder only reads 100C all the time. The bed and Extruder 1 work fine. How do I fix my printer to read the proper extruder 2 values?
Extruder 1 is a genuine E3D V6
Extruder 2 is a Velleman K8400 extruder.
Using https://configurator.reprapfirmware.org/ I get these values for the Temperature setup portion of config.g

M143 H0 S250 ; Un-comment this to set maximum extruder temperature, default is 262C
;M141 H3 ; Un-comment this to set chamber heater/thermistor channel

M570 S180 ; Hot end may be a little slow to heat up so allow it 180 seconds
