That is a new part that Opt just came out with for the XT8 laser. The one I have is a prototype, but it works very well. It pretty much keeps all the reflected light down at work level. It fits over the end of their air nozzles, so it would probably fit onto most of their lasers.
6:24 @Jim, how did you connect your laser touch off rod to chassis ground? I just checked on mine today and there’s no continuity. Did you just connect a wire from some metal part of the laser to some metal part of the CNC gantry or something? Is there any safety issue either isolating or grounding the laser to the chassis?
Hi Ryan, The laser rod clamps are bolted tot he universal adapter plate (there are a couple of convenient tapped holes there already), and all the rest of the laser mounting hardware is metal so it all conducts through to the Z stage which is chassis grounded several ways, the best being the spindle wiring. So all I have to do is attach the magnet wire from the touchplate somewhere on the machine's chassis (i like the rotary unit because its got lots of steel) and then the laser touch rod or the spindle will trip the touch plate. I plan on added a 3D probe soon, and I will probably just wire the touchplate ground to chassis so that I don't have to drag the magnet and wire for it around.
Perfect timing I just got my xt8 jus waiting on my air assist to come in. Can’t wait to do some cutting
Jim is our pioneer in the wild laser west.
Thanks for blazing the trail!
Very interesting ! Thank you. Can you tell us more about the little safety glass ? First time I see it. Do you have the same for the 15W?
