I really dont think your pdf is in any way contravening forum guidelines in terms of a commercial interest
According to what I read , you use a Z axis encoder to vary power levels , how do you derive the Z axis info -- I don't know Mach3 - so is it some sort of transform mach 3 does to convert greyscale bitmaps to variable Z axis height to do a 3d type carving?
I also note you DO say this wont work for higher powered CO2's
What is the lifespan of such a diode , what does it cost with heatsink et al?
I wonder if such a device could be used to ablate a resist for electro or chemical etching of metals?
What other substrates does this work on? anyone tried clear acrylic?
Anyway , its great that you share this with us , it definitely does have some overlap and relevance to what we do here..
