Try putting the R325 into TEST mode by placing a jumper on Pins 9 & 10 of JP1. The
motor should twitch back and forth slightly if the R325 is functioning properly.
R325 not moving the motor (Step/Dip)
Verify that the 5V is being supplied to Pin 1.
The R325 is causing the motor to vibrate and jitter back and forth
Are the Motor phases switched? Be sure to check that motor wires are connected to
Pins 6 through 9, in the order of A, A Bar, B, B Bar. To check which wires belong to
one phase, take a Meter to measure resistance between any two wires. If there is a
finite value between two of them, insert the wires into pins 6 and 7, OR pins 8 and 9.
Insert the remaining two wires accordingly.
