Hello, I'm working on a head-mounted device that requires the use of 6 stepper motors. I am attempting to simultaneously drive two motors in this manner, as shown in the diagram. Arduino is powered from USB, and motors are powered from a 9V battery.In reality, the motors are connected to drivers, …

That battery is not suitable for motors. It does not deliver the current needed. Try 6 AA cells or a real power supply. Nothing the code can fix.

Thanks for your advice. I will try that library.
