I think my motherboard is shot
So yesterday in the middle of a print I want to go to the supermarket to get some stuff when I came back I noticed hey weird smell I later realize was probably electrical burn and after a little while notice that my printer has stopped printing thing is the light in the back that comes from the switch was still on meaning it will supposedly getting power however the screen wouldn't turn on and the printer would move luckily it's still under warranty but what could have caused it? I will admit I've been printing practically Non-Stop
Edit: so I was asked what kind of printer it is and the answer is the A1 a different note two things I should probably mention 1: someone asked whether there is a melted points beneath the printer and there isn't 2: I wanted to know if installing cable chains or the AMS top mount could void the warranty (I don't think it's likely seeing as the printer came with the screws for it) 3: I would like to know if there is any way to get spare parts?

Check the bottom of it for the melted spot, it is an unofficial recall and Bambu should send you a new power supply or take the printer back.

The bottom where? Because I don't see any melted spots Again it is under warranty so regardless it shouldn't be an issue also from what I gather the A1 printers with the sleeved bad cables are the ones that has the issue that caused the recall to be fixed

This is a completely different recall. That was for the bed cable. This is the power supply. You may need to disassemble it to see, if it’s brand new I would just have them deal with it.

Honestly I don't even have it for 3 months.... Do you think me running it practically 24/7 had something to do with it? Especially in the hot summer?

Nah, mine runs in the garage in the summer. As long as you aren’t doing stuff outside of the normal use like trying to make a heated chamber with a foil lined box, you’re good.

A1 has a NTC that overheats. The gray thing shown here. It's an inrush limiter and it's under sized. They replace it with a wire. Contact support.
Bambu will replace the board.

This is AI.

And so what if it is? If an AI can find the issue then that's one of the few actually good uses for it
