Hey @pjh1000! Thanks for posting the request on the Forum!
Just to be 100% sure, have you tested the motor on both connectors (1 and 2), and made sure it was connected properly (black wire matching the black mark on the backpack).
Also have you tried test the motor while the Quirkbot was connected to the computer? I just want to rule out the possibility of the Quirkbot having a faulty battery (and therefore not being able to supply power to the motor).
