JTech 2.8, 4.2 or 7W laser?

I just got the 7w in and after some troubleshooting and set up. It’s pretty freaking awesome. I would say that it is definitely fast I had to mount my x carve to the table. The resolution is really sharp hd focus. To the question about what you can cut I’ve got up ¼" hard maple plywood. ¼ revolution ply would like cut well considering its about the density of cedar.
