Marlin 2.0 MKS SBase 1.3; set driver current

Hi,

I would like to know how and where the current settings for the DRV8825 drivers are defined. I cannot find a default setting anywhere, I can find this on the configuration_adv.h. page but I cannot figure it out (I just don't understand it):



I changed line 581, the number of channels, to 5.
I changed line 584 to have 5 variables, and set the first two (my guess is X and Y motors) to 1.5A
Should I enable line 565?
Or should I enable line 580?
Or both?
I tried to include the library mentioned at line 580 using PlatformIO in Atom, I don't know if I succeeded.
Any help is welcome.

Cheers,

Hugo
