Reprap.me specs (where you can buy the bed) are slightly different :
[quote]Resistance at 12 Volt setting is between 1.0 and 1.25 Ohm (115~144 Watt)
Resistance at 24 Volt setting is between 4.0 and 5.0 Ohm (144 ~115 Watt)
110 degrees Celsius possible for both 12 Volt and 24 Volt
Running 24 Volt on the 12 Volt terminals will heatup the heatbed to 100 degree in only 2 minutes (will also consume up to 576 Watts!!)[/quote]
Hence my Amp values 
Yea, you was to fast with the reply 
Yes You can!
It is actually a āpower expanderā ā¦
cheers,

Is there some one that have a spare power expander?
Im still looking for one
You can buy them pre-made on http://www.reprap.me.

hello,
ive now mounted my heatbed in the middle of the alu plate. now the startposition of the printhead needs to be moved. but i donāt know how to do it.
is ther someone that can help me?

Hello,
Iām new here, just bought the K8400.
Iāve built it together now but was indeed wondering how to get the heated bed in.
Iāve ordered a normal stock DC relay + heated bed mk3 + 24V DC power source. I think that would work out connect the + and - from the pcba to the relay, relay then connects 24V to the heat bed.
But there remains a key quesion for me:
The heatbed connection on the PCBA has a 4 pins connector, does anybody know what the different outputs of the pins are? (especially what the switched + and switched - are to connect the relay?
Thank you very much.
greetings
Coen
The pins on the PCB are the same, you have 2x + and 2x -.
