I check twice on the current source output the result still 12V; my electronic was gen6.d and my firmware is [github.com].
do you have anything to make motor axes move?, and my computer spec was windows 7 ultimate 32-bit.
Try talking to it with a terminal emulator such as Tera Term. If you have the baud rate correct it should print "start" when you hit reset. The type "G1 X10" It should move the X axis 10mm.
