First - disconnect your L2M2. from the motor.
try connecting the neutral (blue) and the purple wire without the l2m2, then switch on your setup. the motor should start running for as long as it gets power.
if it does, power off everything again, change the purple with the brown wire and switch back on - the motor should run in the other direction.
if it does run in both directions this way, your motor is fine
---
keep the motor disconnected from the L2M2.
if you turn your wheel RIGHT, the CCW led should light up (trying to turn the wheel left).
now turn your wheel LEFT, the CW led should light up (trying to turn the wheel right).
