I have an ender 3 v2 + cr touch running klipper mainsail.
Everything has been working fine till i had an issue with my hotend which had a leak wuiith filamenrt all over the heat break and nozzle.

The new hot end required new cabling to the mainboard which was completed.
When turming on the printer and pi, i get the

I have checked and rechecked the connection between the mainboard and the hot end can cannot find anything wrong.

Can anyone please help to advise.

Hi @bobster316 ,

That high temperature typically indicates that either the thermistor type is improperly set or thermistor wires are shorted somewhere.

From the product description, you should be using a “NTC 100K MGB18-104F39050L32” sensor_type.

[extruder]
...
sensor_type: EPCOS 100K B57560G104F

I already have theat configured in my printer.cfg

Sineos: Deleted the unneeded and unformatted paste.

As indicated by @3dcoded. Set correct thermistor type NTC 100K MGB18-104F39050L32

Sorry. I put the wrong sensor type in the code block. It should be:

[extruder]
sensor_type:  NTC 100K MGB18-104F39050L32

Tried this code, no difference.

Could you please send an updated klippy.log with the new config?

Thank you.

You changed the heater_bed thermistor, not the extruder. I would change your config to:

[heater_bed]
sensor_type: EPCOS 100K B57560G104F

[extruder]
sensor_type: NTC 100K MGB18-104F39050L32

I think I found the issue, I I checked the resistance of the thermostat and it was showing zero so I remove the thermister from the hot end and it looks like it was damaged. Please review the image and confirm this is the case.
Thank you.

The image is a bit fuzzy, but I can see one of the thermistor wires is completely disconnected from the sensor. I would install a replacement thermistor.

Thats correct one of the wires is disconnected from the thermister, this was the oissue all along.
I am trying to get a replacement.
