err tempmin taking off an extruder

#1
hi guys,
I need some hints,
i had an issue with an extruder, i have two, I want just to take off one for a while but I get the text ERRTEMPMIN if I do so... how can I solve that to keep on printing with just an extruder? Thanks a lot

Min temp error is caused when the connection to your thermistor is not reliable or in most cases not connected at all.

You will need to upload single extruder firmware if you want to take the second extruder off. With dual extruder firmware, the printer is looking for connections to both extruder's thermistors.

Here is the tutorial on uploading firmware. https://www.youtube.com/watch?v=nZAqgStiEsY
