Bed heating ?

[Jano46]

Hello, on my A10M I have a problem heating the bed, it does not heat the screen indicates 280 degrees the resistances are good (2x3 ohm) as well as the thermistor (120k) all being measured at the main board . Do you have an idea ? Thank you

Hi,Can't your heating bed heat up properly? You can check if your heating bed line is connected normally. If you unplug the heating bed line from the motherboard, if the temperature shows -14.

TNX William , it’s the same plugged or unplugged , I read 280° on the screen and the nozzle is OK . Have a good day.

Hi,If the hotbed cable is unplugged but the temperature still shows high temperature, the motherboard may be defective.

thank you william this is also my opinion. I'm going to ask geeetech for a little help and especially a 2560V3-1 circuit diagram

Hi,You can download the schematic diagram on the official website.

yes but I'm not sure that it is the version 3-1 used by the A10M. the manual is not the right one.
