Hi,
The motors don't get hot at all, and neither does the driver board.
I don't know what motors they are, they are no doubt pathetic as they come with the CNC3040 and are small.
I stuck my LCR meter across one of the connection to the board. It tells me 1.93mH at 15KHz and gives 1.4R DC resistance.
I stripped back the wires at the motor end. There are actually 6 wires coming out, 2 of which are not connected at all, and the other 4 go to the board, so it seems I don't have any choice about series or parallel.
The resistors seem to be one per phase and are 0.25R. I thought it was 0.4R because the meter probes have a small series resistance.
Oh and the dip switches are set like this:
