Good result for 1 pass. What kind of swarf did you get with that? Enough dust to notice? On travertine, I noticed a tendency for it to build up in the corners and fuse there, it had to be scraped out between runs.
Dimness like in the UI photos? If so it’s not bad. The big difference is that it’s a single bright led in the middle, not strips. I’d imagine shadows might be a thing with larger items but I haven’t really noticed it with flat stock.
On the other hand it’s a small machine with a white interior so maybe the light will bounce around enough that shadows are filled to the point of being a non-issue?
