October 5, 20241 yr Author Diamond drag engraving is surprisingly fun and easy. I decided to buy a spring loaded diamond drag engraver and do some experimentation on feeds, cutting depth, stepover etc. I ended up. 90 degree drag bit. tip flat estimated at 0.128mm, 0.1mm step over, fill crosshatch at 0 degree, 700mm/min feed speed. Far better results than using a V bit, much less sensitive to the material not being totally flat and far far faster.
October 5, 20241 yr Nice James. Now change the face from Times to Arial and it will look even better.

November 28, 20241 yr Another option for the desktop CNC machine that I purchased from Snapmaker works as well. The working space makes it easy to fit the whole chassis unit with the enclosed cover. It has two different laser modules that work perfectly for engraving. I have some pics shown while I was working on the GG upper and front panels. Milling the holes for tubes, Stax jack, and screws. I settled the speed to 100mm/min and 0.1mm step which gave me the balance of speed and a nice outcome. The bit is from Datron, 3mm Single Flute End Mill. I have another 2mm ball end bit from Snapmaker which I also used for milling the M2-size screw holes. The only complaint about it is the limited 200W CNC power which does not allow the drilling process. The 8nm laser module is the most satisfying. Easy to manage and nice outcome for the front and back panels engraving.
