![]() ![]() In other cases, it could result in undefined behavior. Which in practice would mean the motor would rotate backward one step (instead of 3 steps forward). If you give it 3 steps forward (while the motor is disabled) it would drive the coils (once you re-enable to motors) as described in the lookup table for step 3. I you are, for example using full step mode, and the motor is in step 0. I think this is profile produces more torque, but is less smooth. ![]() In the second image, you can see that only the Y coil driver is at 100% in step 0. This will make the stepper rotate more slowly. But for example, in the first image, you can see that the current in the X coil will steadily increase, while the current in the Y coil will steadily decrease. I'm not quite sure, as I would think the last two diagrams should actually be squares. It describes the current going through the two coils of the stepper motor at each step. ![]()
