Should I change the distance between the third mirror and the focal lenght or should I go whit the same distance as it was from the third mirror. And is there anything else that I should do while changing from 2,5" to 1,5 " focal lenght, or just adjust the distance from the material as 4,16cm.
I have Co2 laser cutter 80w and was using till now 2,5" focal lens
