I have built a 4x8 ft cnc router with 4 nema 23 stepper motors, im going to slave two of the motors together for the x axis. the board is a tb6560, with a 15 amp 24 volt power supply. the router is working good except for the y axis. the y axis is not moving it makes a really low noise whenever i try to jog it. i ve hooked the y axis motor up to the x axis and it worked perfectly. i figured the problem may be the wiring so i took the motor off of the router and conected it directly into the y axis on the tb6560 board and it still only made a low sound and would not turn. im guessing my problem may be software related or somthing wrong with the board
