Hi everyone,
I was planning to add a heated bed on my #replicator2 . I already bought this PCB (PCB Heatbed - RepRap) and looked a bit how to connect it to the main board.
I already know I’ll have to change my power supply.
My main questions are about the thermistor…

  • I already bought NTP 100kOhm radial thermistor and do not know if it will fit my needs.
  • I don’t think so, but… is there a polarity to the thermistor?
  • what are the pins to connect with? It seems that they are 2 and 4 when the power is on the top of the connector.

Thanks a lot for the help…

Thermistors do not have a polarity.

Thanks a lot @paul_wallich
I will now have to search which thermistor had to be plugged in and if I need to flash the firmware with an updated one.
