Thank you everyone for jumping in, I really do appreciate it. This community is awesome.
@dougl I cleaned my lense and check the o-ring to ensure it was secure.
Everything is as secure as it can be. I have a K40, my first laser, and that thing is wobbly. I mean how can this flimsy piece of metal hold that mirror stable?? The K40 doesn’t have this type of pattern going on. What an amazingly cheap piece of tech that just works.
Here are the settings I have setup for FluidNC.
I don’t think my acceleration values are out of the question. As a matter of fact, the image in one of my prior posts that I engraved on pine (just a square) I had adjusted the acceleration down to 1000 mm/sec2.
Sorry for this, the forum wouldn’t let me upload a text file???
