Comment on [Troubleshooting] It's the clog guy again - temp readings are bad!
Damage@feddit.it 2 weeks agoAre you saying that the wire is all in one piece from the thermistor to the board, with no other connectors in-between? Meaning that replacing the thermistor also replaces the whole wire?

Precisely, I’ve seen a lot of printers have a control board on the hot end to which the heat cartridge and thermistor are connected, with a ribbon cable running from the hot end control board to the main motherboard.
My printer does not have this secondary control board. There is a 1.5m wire running from the thermistor all the way to the main motherboard, same as the heat cartridge. Replacing the unit means replacing the entire connection, from unit to motherboard

You could also have a thermistor with a connector on the wire near the toolhead, even if you don’t have a toolboard. Old E3D thermistors had only about 15cm of wire attached to them.

I’m not sure what you mean. Where does this 15cm of wire go to, if not a control board or simply a wire extension that runs to the main motherboard?

To an extension exactly. That’s why the other poster was suggesting to check the wiring, because it’s a common setup.
