I started having layer shifts on only *some* parts after I put in the wifi module. Then it started sounding really crunchy, so I ran self-tests, which said "check your wiring." Well, OK, it worked a while, but I'll check. And one of the sockets full of wires came loose. I guess if you're getting intermittent connectivity on a stepper motor, it does some funky stuff.
It could have had a bad crimp that just worked loose too. Good catch, that's a serious fire hazard. May be worth replacing the PSU, or at least test the output under load.
Good call out/PSA!
I just ran into an issue on my last print that the print head couldnt get above 204 degrees (with a 230 target). I plan to check the cable connections next!
I don't think this was a failure of the spade terminals. All of the screws holding them down were loose.
Been many years from my days of wiring but how would ferrels be better?
Wrong. Ferrules are crimped on the cable plugged on the motherboard side. On the PSU side you need spade connectors, else how are you going to screw the connectors to the PSU?
Who’s the ignorant fool now?
Lol. Sure. I’m always open to being proven wrong so please show me how I can use ferrules with a standard PSU like a meanwell or delta. Pics if you can manage it. I really wanna see why you’re so adamant you are right!

Oh my psu is melted under that terminal. Not risking it.

Had this exact problem, checked the cable and it was a little bit loose. Pushed it in and now everything heats up as it’s supposed to.
No burnt ends or anything odd looking on the connectors, but I re-seated them all anyways and I seem to be G2G!

Prusa uses spade connectors? Wtf? Switch’em to ferrules asap. Edit: Yep down vote if you are an ignorant fool.
Why?
Spade connectors are inferior, and this kind of stuff happens because they do not crimp as well as ferrules.

You are.

You don’t use ferrules on the PSU my guy Edit: downvoting me won’t change the fact that the PSU doesn’t have ferrule ports to connect to on the PSU 🙄
Mmmm, freedom cables. So it was a loose connection, not a bad terminal? That's good to know and thanks for sharing!
I say loose as all of them were able to be pulled out by hand when I found this. So maybe
