      I have 2 daughter boards, a thermocouple type K board as my 1st board and a PT100 board a thermocouple type k board. I can not get a reading from the PT100, just the 2000.

      It is a 2 wire connections in pins 2&3, with the jumper between pins 2&3 in the right most positon, (middle pins). Here is the config file settings
      ; Hot End Heater H1
      M301 H1 S1.00 P10 I0.1 D200 T0.4 W180 B30 ; Use PID on bed heater (may require further tuning)
      M305 P1 X202 ; Configure PT100 for heater 1 - 2nd daughter board 1st connector
      M143 H1 S120 ; Set temperature limit for heater 1 to 120C

        With a 2-wire PT100 connection you need a jumper between pins 1 and 2 and another jumper between pins 3 and 4. Current production PT100 boards have jumper pins on the PCB to make this easier.
