Hello. I am back.
I purchased a new Theta lens, sized 160MM, stamped on the side, where my engraver came with one stamped with 420mm on the side, but the machine has a label that instructed me what to put into parameters (F3).
For the new one, I am following instructions from this fine thread:
https://sawmillcreek.org/showthread....-for-the-fiber
I take 160MM and divide by the square root of 2, and get 113MM, so that's what I entered into F3 and also workspace. I then drew a square 113 x 113, engraved it, measured and then followed the instructions on how to enter so the square is 113MM (or so) on X and Y when engraved.
Problem I am having is that the 113mm engraved square "bows" outward between each corner, and not sure how to adjust so it's a true square. I know in F3 one can adjust, but as I fix the X bow, the Y bow gets worse, and vice-versa. I assume this not being square will have an impact on the alignment of engraving.
Any tips on how to adjust, or if someone who has a 160MM lens can share a screenshot of their f3, that would be great.
