I'm working on a 3D Printer that works with 5 Nema17 Steppers (1,7A/Phase). I don't need a heated bed or a heater for the extuder.
The maximum current the Printer could consume should be 17A which would never happen. Just from what i've read (this is my first printer) i should be fine with 7A - 10A if i am correct.
But yesterday i measured the current when moving the different axes (just moved them through Pronterface, one axis at a time) i measeured a maximum current of 100mA. I mean i have to made a mistake when measuring right? Or does the power comsumption go up significantly when you print a real model and move more then one steppers at a time?
On another note: I made my U_ref = 0.67V on the drivers. Do i need double of that for the z-Axis if i have two steppers?
