I just bought 4 Solarbotics RM2 motors for my gm3 gearboxes. These are the black ended motors. (at least the Solarbotics catalog shows black ends I got white).
I am also using the DC Motor Driver 1.1 board to drive the motors and I am not getting enough current to the motors. So my torque is not enough to extrude. I have moved to my original motors.
I have not yet swapped the wiring just to make sure it is not causing an issue I hope to do this tonight.
I was posting to see if anybody has had this problem and also if anybody knows how much current is needed for these motors? I do know the DC motor driver is suppose to give up to 750 ma.
