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.
XPro is stand alone (has built in drivers) does not have outputs for external drivers, all you need is a $16 Arduino Uno for that.
