Anyone moded the heatbed cables to prevent fire hazards?
Hello, I've just this picture of another MK3S user, that has suffered a spontaneous fire hazard due to the constant flexing of the heated bed cables. Have any of you implemented any additional mods to prevent this? It has scared my quite a lot to see this, as I usually leave the printer printing at night, within an enclosure. I've already bought a wifi-connected smoke alarm and a fire extinguishing ball just in case...

I've run my printer for about 5 years now, while not constantly it does print 3-4 days a week on average, sometime 1-2 day long prints too. Never had anything remotely like that.
Personally I would be questioning if it was assembled correctly in the first place. Heat is usually caused by poor connections. Only time I've have seen reports of the same thing is when the wires were attached to the wrong side of the bed.

I think it cannot do harm if you check all the screws for power connections (electronics board, heat bed, and the PSU) from time to time for tightness. Sometimes they can come loose caused by the heat cycles. I know that this has happened with screws that I had checked myself before.

This was clearly an incorrectly assembled heatbed connection. I have seen softening of the cover after extended high temperature printing (which is why I now reprint this part in ASA or PC-CF) but it certainly shouldn't go off in flames.

Thanks to all for the reassurance. Nonetheless I'm installing the fireball extinguisher and the wifi-connected smoke alarm to feel safer.
Many thanks!
