I bought a complete MK8 replacement extruder set that comes with 100k thermistors, but they dont work on my mightyboard. it starts to read them and then goes ;lkajsefoiwa’rlkja’oivhha;lknve

Should i be able to change the thermistor from the existing to the new ones in the firmware? any suggestions?

The ctc uses a type k thermocouple not a thermistor. Re use ones of your original block.

I know this is an old topic and likely has been resolved but for the sake of anyone else that finds this as useful info, I am running on both my CTC and my Replicator 2 these thermocouples Amazon.com 21 with a non insulated ring terminal http://amzn.to/2gwIQpP 18 crimped on. I have been running these for a combonation between the 2 printers for around 500hrs now.

As adamcooks says you will indeed get interference if care is not taken, it is not only annoying when it gives incorrect readings that screw up prints, it could be damaging to your board, as a work around I simply wrap the thermocouple, or the ring terminal tip in some kapton tape http://amzn.to/2hJtUWH 10

I also clipped my original thermocoulple wires up above the extruder a ways an installed these plugs Amazon.com 14 this makes changing out thermocouples and servicing the extruder easy, no need to unhook at the board. I also used RC style deans plugs on my heater cartridges, and fans http://amzn.to/2httPaq 7 same deal make it easy to take apart for maintenance.
