Hi All
Recently started a conversion of a Cube Pro to run on Klipper. All going well until I got to the hotend. I’m using a creality K1 Hotend purchased from Amazon. In the fluidd console the temperature readings are 520c at room temperature. I have been unable to find the correct sensor type to put in the “sensor_type” field so am assuming this is causing the issue.
I would really appreciate any help with the sensor type I should be using for this thermistor. Please see the link below.

Hello @carptench2014 !

And the klippy.log?

Please attach it to your next post.

From the printer.cfg on a K1.
sensor_type: EPCOS 100K B57560G104F

Thanks Napcal
This is the sensor type I am using.

Then the K1 interface board may be using different electronics along with that thermistor, or there is something in your cfg.

Post your log as requested by EddyMI3D.

If your sensor definition and pin is correct, then you likely have a wiring issue.

@Sineos

Thanks but I did post a log, not my build, trying to help @carptench2014 who is the one posting this issue.

LOL, I know. I was referring to the fact that @carptench2014 answered to you posting his log and again answering to @EddyMI3D with the same log. I only wanted to make sure you do not accidentally mix logs :wink:

New to this sorry.

You were correct thank you. I had the Thermistor wires mixed up with the heater wires.
Switched them round and all seems to be good now. :joy:
