I think the PSU's 4pin terminals may have a big problem, and their contact is poor. Therefore, we recommend that you solder the PSU cable directly to the motherboard's power input.

I have no idea how to solder, I wouldn't feel safe knowing I couldn't disconnect the power if I did and plus, its too late now.

You can ask the sales to send you the replacement.
Then you can change it.

mine has just done exactly the same but luckily I was near it at the time and able to take it outside to clear the smoke from the plastic melting.

this is really dangerous.

I've experienced the same issue with mine as well - purchased in 2015. This is definitely a fire hazard. In addition to the PSU connector having burned I noticed some scortch marks on the bed heater connector to the gt2560 as well. What's the advised path of action to remedy this? As of now my printer is out of commission. Thankfully there was no harm or damage done to person or home. I'll try contacting Geeetech via email too to get some guidance.

For background:
I was printing PLA at 206-212C
Bed Heater was at 60C
The printer started showing intermittent heating problems
Over the lifetime of the printer I've only gone through less than 2 kg of PLA.
Firmware was upgraded from marlin 1.1 to 2.0 - with thermal runaway protection (which was tripped often but I didn't realize what was happening)

Hi, Your power cord plug looks burnt out,
Whether the voltage range is adjusted to the voltage range you want,
The heating plug also looks burnt out.
When the voltage is normal, you can check whether the thermistor on the hot end is fully connected
And can be measured with a multimeter.
