I have a Kinetic artpiece i'm currently making controlling 10 stepper motors (NEMA 17 + DRV8825 Driver) simultaneously with 3 HC-SR04 Ultrasonic Sensors on a Arduino Mega 2560.
I need to know what power supply I would need to power the whole system?
And can I use the same supply to test on 1 motor or do I need to reduce the amps with a resistor?
I saw that I also need to set the Motor Current Limit on the DRV8825 Driver.
I found that you need to divide the Imax by two ,That would be 0,9V. Is that right?
Someone recommended me to -10% off the vallues to be safe ,that would make it 0,81V
This is the datasheet of the stepper motors.
I hope I gave enough information...
I’d really appreciate if someone could clarify this
