I have a Taz5 with a Dual V3 head on it and recently had to replace the thermistor. I used a E3D thermistor (E-SEMITEC-50-MOLEX) that is available on Amazon. It seem to be the same encapsulated unit (Semitec 104GT) that is originally on the head, and worked well for a few prints. Then the temp reading dropped by around 8 deg when idle and cool as compared to the other head (and bed) and who knows how much lower when hot. This started causing issues with prints, so I figured I got a bad one and replaced it again. Same issue. Is there something wrong with these compared to the ones Lulzbot doesn’t appear to sell anymore? It there a bad way to install these? I soldered the molex connector to my lines and can now replace it easily using the molex connector it comes with. Clamped it in with only light force on the screw.
