A newbie builder here but with plenty of electronics experience. I made my first laser controller by putting together an Arduino and a grbl shield. However it all needed to be hooked up with separate wires and eventually one of them would come loose and everything would stop working.
When I made my second laser engraver, I eventually made my own custom board. Its a custom Arduino with four DRV8825 motor...
