Adding Laser Engraver to CNC Router and Activating in Mach3

I wanted to add a laser module to my CNC router so that I could label parts as they were machined. The advantage to doing this on one machine is obviously reduced setup time. The laser module I used was an ElksMaker 2300mW 445nm blue laser. I got this off ebay for ~$100NZD (70US) https://www.ebay.com/itm/445nm-2-3W-2300mW-Blue-Laser-Module-With-TTL-PWM-For-DIY-Laser-Cutter-Engraver/322382603217?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649… Read More Adding Laser Engraver to CNC Router and Activating in Mach3
