You are the very first person I have heard mention this about the Qidi machines, though I have heard of this being an issue with alot of clones.

I print almost everything in ABS. I run my machine from about 8am to 2-3am every single day. I check all wires and connectors when I do the weekly maint breakdown on the machine. That plug still white as the day I got it.

But still a good heads up, def something to be mindful of and keep an eye on.
Glad to hear it. This burning down my house with the smoking then this was my tripping point. I looked on the internet and found a few links of some seriously burned up connectors (black) and one had this happen after a year and another had this happen at the Mightyboard but this was a different printer not a Qidi. I measured the ohms on this plate and I was wrong it is not 3.4 it is 2.5ohms (I forgot to zero out the meter) so 24v at 2.5ohms that connector is not made to handle that much current.

I don't know what the connector on the Mightyboard will handle but if it is like my Ramps board 10A is hot but not melt down and burn down your house so that connector should be fine. I suggest looking at it as well every so often (it is orange and on the right hand side when the front door is towards you).

What gets me is 20-25mins to heat up the bed tells me they are using about 7-10v PWM to it because they know a full 24v would melt it in a heartbeat. Lets say 8v @ 2.5ohm is only 3.2A but I do believe that white connector is rated around 2.5A-4A max so be very cautious.
