Nice job, I got a lot nice ideal from watching your video, quick question , are those magnetic positive stops and does the laser have protective lens cover/ window and how often do you have to change them before distortion of laser. appears?
Yes, those are magnets that I used for stops. Most of the time I don't bother with stops for laser work because the object doesn't move. The main exception is paper and cardboard because the laser fan and air nozzle tend to blow them around. In this video, I just threw the magnets on there because they were handy and I needed to make sure they didn't move even a few thousandths. On the lens cover question, Opt lasers don't have lens covers, the main lens is exposed inside the air nozzle. As long as you always use the nozzle and don't forget to turn on the nozzle air pressure, or get a spider inside the nozzle (that actually happened to me once) the lens will stay clean. I don't do production work (I'm just a hobbyist), but I have run a couple of laser picture rasters that took 7-8 hours and the lens wasn't dirty. I run about 5 lpm of air for light engraving, and 10-15 lpm for heavy engraving and cutting. The outside of the nozzle can end up very dirty, but nothing seems to get into the lens area.

Very good, I learn a lot/get a lot of inspiration from your videos.
Love the probe mount - I`ll copy that one 🙂
Great vid like always! :3
