I just bought Glidewheel -M.http://www.mindsensors.com/ev3-and-nxt/18-glidewheel-pf-motor-controller-for-nxt-or-ev3?search_query=glidewheel&results=4In EV3 mindstorm education edition, I updated EV3 firm version to 1.09.Then I downloaded Glidewheel -M EV3 block software library, and imported it.I connected cable to port A and connector to PF M motor, But I got an exclamation mark next to port A in the glidewheel M block in the program, and the PF M motor didn't move. Please help!In addition, I tested the PF-M motor. When I turned it, it generated ~1000 mv DC. But when I tested the Glidewheel -M connector to PF M motor( with glidewheel M block specified "ON") , it didn't give any voltage. So I think the connector to PF M motor is not working. Looking forward to your help!!
