Fixed bug with random pause and temperature error
The printer has a random start temperature drop or starts to rise and fall. After receiving a printer error message for a short time, the screen can be updated with an error such as a temperature error or a heating error.

Hello.
I have the same problem with my A10M.
Can you explain please what is the reason of the problem and what is the solvation?

Hi, does your temperature fluctuate widely? Whether to check whether your thermistor is fully connected,
Does this happen for all models?
If not, it may be a problem with gcode itself;
If you have checked all the above, you can try flashing the firmware.

The temperature doesn't fluctuates widely. Just a couple of degrees. Than it begins to fall and printing stops. After turning off-on the temperature cannot reach the needed one and "thermal runaway" again. During this hotend coolers began to work unstable too. Sometimes sudden stop of printing happens without any messages. When the sudden stop happens the voltage of the power supply is very low (less than 10 volts). After some time it's 24 again. I suppose it goes to some protective mode.
This happens not every time. Sometimes everything is ok. Sometimes it happens after several hours of normal printing. And there is no any dependence on model or something else.
It doesn't depend on gcode or model for sure. The firmware is also ok because the seller resent me the mainboard, I changed it and the problem is still here. I reconnected all the wires. Don't know what to do. The seller's support told that the problem is with te hotend, but sent my the mainboard somehow. Now they sent me something else, I don't know. I'm waiting for the package now...

Hi，You can check if your hot-end wiring is fully connected,
Measuring thermistors.

I still having this problem on my A10M, I updated their firmware to the last version and check all wire connections, but the problem is already there... Has anyone managed to solve it yet?

Hi, You can check your thermistor wiring,
Then measure the thermistor.
