Very nice looking machine there!

Someone else can explain grayscale better than I as I have not done much of it, but here is my outlined view of it.

First, set your job to gray scale
second, set your min and max power for the laser
Third, set your min (raster) and max (rapid feed) speeds

Search on the forum. There are many who have setting dialed in pretty good.

I ended up using polycarbonate, has better material properties. I did a material science paper last semester so now have a better understanding of mechanical and chemical properties of some materials. I also rebuilt the frame with a square and level its all. Belts aren't crazy tight but is working perfectly.

Nice work, now just a few more tweeks to get you circles set better

Yes, I did notice those small bumps in the O's, the weird thing is when I load the test circle file it engraves without that "bump"
What sort of tweaks do you think might fix those bumps ?
Do different fonts behave differently?

This was my first attempt at gray scale, seemed to work well, and I tried with velocity on too, which also worked and was a more gradual increase in darkness.
