Got nice help last time and now I have one more question / information combined thought.
I have managed to make my first cuts with different results, not completely satisfied than with a little thicker and harder material such as Plywood for example.
Fails to cut through, either it will be burnt and wide edge at the top or it will be fine lines but not depth.
Have not installed air assist yet but it seems that you need it.
Question: is it to blow away the smoke or blow clean in the cut, that you use air assist !?
Following all the rules of the art, I have used a magnifying glass X10 with ND filter to be able to set the point of intersection.
I get a sharp at the edges rectangular oblique 45 degree shape, which in IRL just looks like a little dot.
My laser is a Neje 30 w, Standard and regular I guess, belongs to the “Master 2S MAX” series, so we know which one we are talking about.
In the manual I can read that the “right” height to get the right focus is between 20 - 30 mm from the underside of the laser module to the work surface.
Now that I have set mine, I do not come below 42 mm from the underside of the laser module to the work surface.
Maybe this is customary and that the rest of you have had the same experience !?
Question: What is your height?
Would be interesting to hear what you have and done about it.
Related: I have cut in fomeboard, Black 5 mm with good results, but wonder why the fome is looks like it does, see picture.
It’s 1 pass, 80 power, Speed 500.
If you have any comments, I warmly welcome them!
Thanks in advance, Petter greets
