I bought this board, a 6560 3 Axis board.
I put 12 volt supply and tested it with only 1 nema17 motor on the X axis.
the jumpers on the board are set to the lowest current, 20%, which say its for giving out 25% of current, which shuold be about 1.5A per motor,suitable for nema17 motors. The range of current being 1.3 to 3Amps.
I left the motor connected. In about 5 minutes, I could not touch the motor without getting scalded. A little more and perhaps I was about to see smoke.
Immediately i disconnected all power and put the motor on a cool metal object to take out as much heat as possible, hoping i did not do any damage to my motor.
Can someone tell me why my motor got so hot, nearing burning temperatures?
Also has anyone used Mach3 to control this board and what settings they are using or recommend?
Thanks
