Below is an advertisement for a replacement board for the K1c printer. This is NOT the correct board for this printer. The board is for the K! max. The difference is the missing connector for the 24v bed heater (Outlined in Blue) and the associated mosfet transistor to control the bed heating (Green). The K1 Max is frittered with a 110/220 volt bed heater and is connected to the socket (outlined in red ). The K1max has a solid state relay connected to the socked to switch the high voltage.
Othe suppliers are also displaying the incorrect board.
The board displayed below is the correct board for the K1C printer. I have checked the board in my printer and it is the same as this one.
To add to the confusion both boards have the same part number
