M3 Motors Specs

Hello.
I purchased a M3 KIT and was my first CNC Machine.

Now I am making a redesign using such machine and I want to know what is the current ( Ampers ) of motors and what Nema type are there.
( I read on manual PDF about are Nema 17, just for be sure )

Are there 1.5A, 1.7A, 2.0 Ampers ?

Thanks in advance.

I included a photo of motor

They are about 75 ounce inches with 1.5 amps

Just another question:
How do you get voltage Ref = 0.6 V on DRV8855 drivers?
( If you can supply me the formula will be great! )
Thanks in advance

No problem. On DRV8825s, current in amps to the motors is 2 times the Vref value. As such, the motors are supplied with 1.2 amps which is enough current to do their job while also lasting for decades of service.
