This is the first hobby board I have put together and the motors don't have near the torque as they do with my other two controllers. I'm using the same transformer and filter, (24v, 10amp) in them. They are 3amp 8 lead motors 280 oz 2.7v. I have one mill that the screw is a little off when it gets to the end and it stalls the pro no matter how I set it. My geckos don't even know the screw is off. I have tried 1/2 step and the controller turned all the way up. This is the same on all three axes. Is this normal for this controller or do I have something wrong.
