Hi,

thanks for the reply.

Here you can see the requested pictures:

This is the old board:

This is the new board:

The only difference is the connector on the bottom left. On the old board, the connector is facing left and on the new board, it is facing up.
Both are 2560 rev B.

Please tell me, if there is anything else you need to know :)

I made sure to replace the board with the exact some board. Therefor I am using a 2560 rev B.

On the board, everything looks the same so no different connectors or anything like that).

I uploaded Marlin 1.0.4 the firmware for the MeCreator 2, which can be found in this forum.
At first everything seemed to work but as soon as I connect the extruder-stepper to the board using this long thick cable on the back, the hotend temp shows 356 and therefore the board goes to
what makes it even stranger is the fact, that the heater nor the temp-sensor is connected to the PCB at this point.

I already made sure, that nothing on the PCB is connected wrong.

Another thing which is pretty weird is that if I set the temp of the bed to 60C it goes up to 60 but the bed is not really warm. If I set it to 135C the bed will get warm but not 135C hot.
