how to connect 3 wire laser to arduino cnc shield rev 2.7
« on: June 06, 2017, 02:51:43 PM »
I just purchased an Arduino cnc shield rev 2.7 to add end stops to my Eleks 2.5w laser engraver.  My problem is the board does not seem to have a spot for the pwm wire.  Can I use this board with my machine?  And if so, how do I connect the laser to it?
