I have the board running for about 6 months now and really enjoy it! Recently I powered it up and noticed motors 1 and 3 are not working. I changed the motors to use motor 2 (no issues) and the motors work fine. However, when I send any commands to motors 1 or 3 which are the X and Z for my machine, they do not move and I don't see the green light on the board indicating signal is sent to the motor like I see on motor 2. When I power or reset the board, I see all 4 green lights come on for a moment and I can tell all motors are receiving a PWM as they cannot move during that second, but trying to send a signal to them with gcode or a test trying to make a circle does not work, I am only able to move the motor 2 for a straight line.
Is it possible to send the board back and get it repaired? I will be glad to pay, I just want to get it working as I really like this board.
Thank you.
