I just replaced the motor driver board and the motor with the encoder board attached to it. Both motors are now responding to commands, but they move very sluggishly, as if they are struggling to turn. What could be causing this? The motors still don't seem to be jammed by anything. I'm worried to keep running the engine because I want to prevent any new damage.
