Why is the spare red/brown cable with white connector for?

Recommended Posts

hello all,

I hope you enjoy the weekend :D

I was busy assembling my UM2 with the 35 Watt heater I bought some time ago from @Didierklein.

But when removing the old heater through the black sock, I noticed there is a spare double cable and white connector in the black sock? (it's was in the sock for me between the feeder and the hotend)

Anybody who has an idea what's it for?

It has a red and a brown wire and at the end a female white connector (same one as at the end of the temp sensor).  I forgot to take a picture. :)

Think it was meant for an additional safety sensor they never implemented....

anyhow it's handy to have an additional cable  :)  I use it to power my 24V hotend fan on my E3Dv6 ABS machine...


Why did I knew before that you would know why the cable is for? :D

Thanks a lot @ultiarjan, I was afraid I disconnected a cable while pushing the heater through the sock. But all my fans were running so I couldn't figure it out why the cable was for.

thnx again!
