@ttraband Yep, totally correct, along the X axis absolutely makes more sense. Cross the “common solution” please 
I’m not deep enough in the topic yet (obviously 
), was trying to visualize my thought in reply to Dan’s post before.
@SupraGuy “LR can deviate from square while unpowered, and returning to square is unenforced” ah, didnt know that too. Maybe I have to look for some pro’s & con’s of the build, just to be aware of what to look deeper into and to take care of. Thanks for pointing that out.
I thought the A6040 was 40W (as of the 40 in 6040) but sure, the data sheet states 10W output power. Input 12V/4A. I start putting the pieces together. I’m aware of wavelengths, basically, from high energetic short blue wavelenght to long wave infrared but havent yet made the connection of how this affects various materials in cutting. As all laser are cutting with heat I dont really get how infrared wavelenght can cut transparent material and blue light cant.
Makes sense with the acrylic shield from this point though.
