How to slove the problem of MAX/MIN TEMP error(GT2560)

[William]

Have you tried the above solution to try?

The above is not a solution. The above only helps to identify a faulty thermistor. I don't have faulty thermistors. This error only occurred after a firmware upgrade.

There is an error in the firmware you have provided.

I have used the instructions and te I3 Pro C firmware shows the termistors are all working at room temp.

But when I load the G2S firmware on, they all read 0.

when I disconnect the thermistor cable, I have -14/0 and when I reconnect I have 358/0, is the motherboard defective?

Hi, if this.
it is the hotbed thermistor problem.
You need to replace it.

Got the same problem. Mintemp message, no matter what termistor I plug (checked on another board, working perfectly), always show 0. But in the moment I plug connector in, it flash for split of a second 20°C, then go back to 0.
When I shortcut connector, it show maxtemp, so it's obviously working.
Even I try to solder termistor directly to pin, to be sure for good connection, still show 0.
So I guess the problem is with board, firmware or such. My question is: possible to fix it or need new board?

Hi, If so, there may be a problem with the motherboard,
You can replace it.

Right. Just one question, update firmware would solve it or not? Actually, I have no idea what version is there and how to do it...

Hi，the motherboard cannot be repaired and you need a need a new board.
