I know that usely, we use one loop with like one step per motor to drive a robot with steppers. However, I tried something else to potentialy have a better torque and I want your advice. I saw nobody that tried what I did. I connected my two motor drivers in parralel and I programmed them like it was only one motor driver. So they both behave the same. However, I'm controlling my self (not with the library) the two directions pins of the drivers so I can also turn with my robot.
What do you guys think? Will the current of 1.35A be too strong for 4 AA batteries in serie?
