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.

iirc, the RM2 is not the 12v motor that solarbotics has. I'd suggest that you call Dan Gates at solarbotics and explain that you need the 12v replacement motors for your gm3


Hell, there are no rules here - we're trying to accomplish something.

Opportunity is missed by most people because it is dressed in overalls and looks like work.
