Hi guys I would like to get cnc -cbeam machine just make holes on electronic enclosure with precision its aluminium 3mm only, which power supply I should order 12 volts or 24,and why. Thank you.
24v because stepper motors like higher voltage. (there is an upper limit though) motors have coils in them. coils have inductance which restricts the rise time of the current. restricted rise time affect both power and top speed. higher voltage reduces rise time which gives you more power and higher top speed. https://openbuilds.com/threads/an-interesting-explanation-about-steppers-voltage-rating.801/
