I am in the process of finalising my first build of an Openbuilds XLarge CNC routing machine. The kit came with an XPro V3 (GRBL V 0.9) board. I am in the process of wiring the machine and have some questions regarding the 5v connections to the board. I have 4 microstepdrivers DQ542MA that each require a signal to pul+(5v), dir+(5v) and then enbl +(5v). Where does that 5v come from? Does it come from the XPro board and, if so, how? Are all the drivers in parallel? Does anyone have a wiring diagram that shows how this should be configured? Your help would be greatly appreciated.
