I have this rigged up to a thrown together cnc machine with 4 steppers and 4 tb6600 stepper drivers hooked up to an arduino mega running with grbl and now with this 5W laser engraving module. I wish there were instructions or google searches with people who did this more but there are not. so here's some tips. I found if I put the dangly cable where the power is coming in from connected to the ground on the arduino and the + on the ttl/pwn thing on the right part it works, after doing the $32 enable laser mode on the grbl settings. then throw in some g-code generated from inkspace with some laser plugin (which puts the m3 and m5 gcode to turn on and off the laser module) in to g-code sender platform, it works very well. I engraved a bunch of phallic objects that I can't really add as another picture here due to it being inappropriate and just juvenile but, what other test subject matter is there than a few huge richards to laugh at. the after adjusting the focus a little it makes a very small ~0.5mm burn dot. I tried it on some wood planks I had laying around which made my garage smell wonderful from the burning wood.

  • Greg Partlow one thing to note, I had this connected to the original power supply that came with the unit. it did not engrave anodized aluminum this way. I connected the board up to the same power supply that drives the steppers which is a more consistent output and now I can engrave on to anodized aluminum at 300mm/m feed. here's a picture of the laser etching into an anodized aluminum business card https://i.imgur.com/cqiM2qj.jpg
