First laser is on it way!
Hello! I just ordered a AF2028 60w Lazer. Never used a Lazer engraving machine. I do have experience with 3D printing, AutoCAD. I have some ideas floating around and I think this machine will make them into reality.

What could be causing this? Inconsistent through cuts on individual shapes...

Hello! I have the same laser model and size as you. I have noticed the same thing when I cut 1/8 to 3/8 plywood (11mm/sec; 20% power). On the right side of the cutting surface, it tends to not cut all fibers in the last layer plywood. I have been using an Xacto knife to finish the cut, or have the laser go on more pass. What I think is happening is the right side of the cutting platform is a hair lower than the left side. I have not tried nor looked into adjusting the table. There should be a way to level the cutting bed jack screws, but again, I have not searched either. I moved the point of origin to start cutting on the left side and avoid cutting items on the right side. If I do have to cut on the right, I either boost power to 25% or slow it down to 9mm/sec and to reduce time of cut, I select only that item to cut.
On a side note, I see you purchased the Auto Focus model. I as well and it worked the first dozen or so tries but now, when I use the auto focus does not stop when it makes contact with the surface. It had pushed through 3mm ply with the tip of the laser and left dent the honeycomb. I have not used it since.
