Bed and Hot End Will Not Heat Up
Hi i just built a 500mm rat rig vcore 3.1 with 2.0 enclosure and the due 3 mini 5 plus.
When i go to heat up the hot end and bed neither will warm up.
i know the sensors are working correctly because when i heat them up with a heat gun the temperatures change on the duet web page.
i know the config file is correct because when i do a pid tuning for the bed and hot end both have power coming out of the board. and the dc to ac converter is working because its light turns on.
but still the bed and hot end do not warm up.
i tested continuity on the bed and hot end. the bed beeped when i tested continuity, but the hot end did not. so the hot end has a break in it some where maybe?
any help is greatly appreciated.

i figure out about the bed. i did not have it wired correctly
this solved the bed issue but not the hot end issue

Are you getting voltage from the heater plugs?

Yes
The thicker black wires are for the heater and the thinner white wires are for the thermister right?
If I plugged them in backwards. Ex. Thermister plugged into hot end 24v.
Would that ruin the thermister?
I checked contiuity.
Heater has broken contiuity
Thermister has intact contiuity
I fix it. The hot end was not fully plugged in. And the bed wad wired wrong.
But both are working now
