hello, i'm really new to arduino and the cnc shield. I have all the steppers wired and working but, I can't find how to wire the spindle to the
grbl shield. I have searched the internet for days and cannot fine a diagram or pictures. I'm a visual learner and instructions are not helping.
Please please, help me. this is the last part of my build and i'm stuck. i'm using cnc shield v3
thank you
Roger
