I think I have it going now. Looks like wire wasn't going into the duex heater all the way. I was able to jam in it and now heats up.

@Rushmere3D This weekend I will put on a table I can work on it. I do the the fans do work with move them to other tools.

Thanks all for help! It was combo that my old harness had wire issue and these 2 fans needed zinc washer. Seems like fan working now.

@jay_s_uk I found long enough cable. So what program would I use? SSH?

@jay_s_uk not yet. I was planning on adding one soon.

@jay_s_uk not sure have cable long enough. Is that only way to get it back?

My duet 2 wifi is running current firmware. Today during a print my wifi not connected. Is there something I can do to reconnect without losing the current print?

I have some zinc washers but ones I have are thick. Going order some from Amazon.

Fans need to be away from stepper almost half inche. Anything can think other than steel washers?

@Rushmere3D so think found issue. If I get the fans anywhere near the extruder the fan stops. I have not tried to steal washers and still doesn't work.

@Phaedrux P106 commands for T1 and T3 don't work. All others do.
