Little help please

Hi Brian,

I'm a beginner too, but your post caught my eye. Firstly, that assembly looks rather easier than my Ender 3 V2 was about six weeks ago; took me a whole day!

Not sure which tutorial(s) you viewed but I had a quick look at this one:

which I thought pretty good.

No smoke, but he did have a problem with one motor plug. I think it was mentioned at 07:50, 11:28 and 13:10. But if you haven't done so, might be worthwhile viewing the whole 39:27 video.

EDIT: Couple of other thoughts over lunch.
1. I'm fairly sure there is supposed to be 'thermal runaway' built into 3D printers, but that seems to have failed if you've got to the smoke stage. So whatever the underlying cause, you might have to fix that too. More experienced users like CA might advise; I think it's via the firmware.

2. Possible causes I'd look for, apart from an outright electrical short or seized gears in a motor, would include a stuck belt or the end-stop microswitches (or their connections) not working.
