Fysetc Nanodlp shield V1.1 Vref points

Hello i am trying to build up a printer with direct control via raspberry. For this i use a Fysetc Nanodlp shield V1.1. Can anyone tell me where to find the Vref test point for the stepper driver on this shield. Until now (in other projects) i used stepper driver seperatly with defined points in combination with the potentiometer to get the Vref. Which points do i have to use on this shield?

typically the adjustment screw "carries" Vref
So black probe to ground and red probe the adjustment screw.

Thanks for the reply. Sounds logical. I will give it a try later. I wasnt sure whether i can use the ground of the 12V shields input or not.

Ground should be common to both the Raspi and the shield.
