About the power pins of the GT2560 board

[astrojhgu]

I got a GT2560 board, and note that it has two powers, two separted pins for the hot bed.
However on the doc, it is not marked, which twos are for the hot bed.

Has any one used two-voltage power supply for this board and do you have the information about how to connect the power?

Thanks.

Hi,the two interfaces are not divided, one is connected to the hot bed, the other is the motherboard.

Hi, thanks for the reply.

I noticed that the two positive pins are connected to each other measured with a multimeter. Is this normal? If so, it is meaningless to use two separated power supplies, just one with enough power is OK.

Also, according to the sch of this board, the pin2 and 3 of the power connector (J1) are connected to each other:

which means that it is impossible to use two power supplies with different voltage.

Hi，this is normal.
