Happy to!
I bought the jtech photonic 7w laser Laser & driver and used the mount posted in this topic (so much helpful info on this forum 
)Interchangeable Tool Mount System, Laser, Needle Cutter, Pen, Drag Knife
The Jtech has magnets in the case so I heated up a piece of steel and melted it into the mounting system along with 2 holes so it could fit flush; probably more elegant ways around this but I was on a deadline and it worked.
For this file, I used inkscape to pull in the picture and then used ESTLcam to carve it. I have used the Jtech inkscape plugin for another project but I usually get at least one warning that a bezeir curve isn’t right or some such and wasn’t confident this burn was going to go through properly. Cant exactly remember the burn rate but it was somewhere between 10 and 20 mm/s at full power.
I was heavily debating on JTech vs NEJE, and I choose the JTech since it was mentioned on the build docs on this site. If this laser ever fails, I’ll be getting this NEJE 40W laser since I know how easy some lasers can be to setup.
Hope that helps.
