Usually the specifications include the coil resistance which, with the voltage, would allow you to determine the current.No, no , no!
I try to be tolerant of other people's contributions but this hysteria is a step too far.
The normal (only ?) way to know what steady state current will flow in a coil for a specified voltage (supplied in this case by the manufacturer) is also to know the coil resistance - in this case NOT provided by the manufacturer.
I never suggested that the OP should control the current in his motor like a "light bulb". The OP had identified suitable stepper drivers in his first post. But one needs to know the acceptable current for the motor in order to set the current limit on the driver board.
If you know an alternative way to work out the max coil current please tell.
