I have the Arduino Uno R3 and the Arduino CNC Shield, a converted computer power supply with 12 volts, 3 stepper motors, 1 X axis and 2 Y axis, used on a DIY Laser Engraver Project in process.
My question is: how do I hook the 2 Y motors to move together to move X axis forward and back? I have jumpered the pins in the clone area of the shield in Y position and plugged the 2nd motor into the A driver. The A controller motor does not move, x moves and the other Y motor moves. I have 0.40 DC Volts running off each driver. So am I doing something wrong, hook up wrong, Stumped.
Thanks for the help, Oh, I’m new to this. .The drivers are 4988
