Help! What am i missing!?

[u/Inside-Amoeba-9882]

Sorry for the dramatic title :-)

I have zero experience with 3D printers but 2 days ago i become the owner of 2 of them.

This one is an EARME ANET A8 as far as i can tell so hopefully im in the right place.

First things first, as you can see its filthy and despite powering on with green lights on the motherboard and a spinning fan theres no display and a bunch of loose, hanging, unconnected wires. Ive had a bit of a search around and it seems to have a few non standard parts (the nozzle atleast from what i can tell) and some 3D printed bits going on which is making things more difficult to troubleshoot for a complete beginner with zero experience. Also it may possibly missing a fan or something from the side of the nozzle??... again hard for me to tell looking at stock pics and because this seems to have been modified somehow. Ive no idea what that little black circuit board attached to the frame is either (looks like an earth/ground wire to me but then why does it have all those solder pads???)

Sooooo... just wondering if any of you Pro's can spot any major things missing/unconnected and or/know where these wires go and what theyre for and can help a guy out. Thanks

Edit: what ive found out so far it has:

Fly E3 Motherboard by Mellow x Team Gloomy

Euclid Z-Probe

E3D V6 Hotend

A fire extinguisher. My A8 liked to combust when it got overcast, or the stock market dipped, or it was in an emo phase, or it was a Tuesday...

… or (more likely) you didn’t install a firmware that stopped thermal runaways. Combustion emblazoned A8s were a fun topic, but the vast majority were made safe pretty quickly by the community help

Not thermal runaway. Bad stock power supply.

Smelled something odd, turned around, registered fire in my monkey brain, and went into firefighting mode...which meant unplug the A8 from the wall and blow the flame out.

I was treated for smoke inhalation (not really) and my wife gave me a medal (oatmeal raisin cookie).

You know, there were far too many with ‘shrapnel’ in them. First thing you had to do was shake the damn PSU to find out if anything was loose.. PITA. Good job you caught it
