Since my stepper motor is a 3d party motor and doesn’t follow the same color pattern I’ve had trouble trying to determine how to hook up the motor to the ramps board the DRV 8825 is attached to. I have information about the positive and negative wires for coil A and B but I haven’t been able to find out which wire to attach where. On the related project page I can see that I need to connect it to either 1 or 2 but I don’t like the 50/50 chance of breaking something.
Does anyone know which is the positive one?
Thanks in advance for any and all help offered.
