I just went through the focus setup using the Lightburn Focus Test after cleaning all my lens. To do this I had to enable the Enable Z Axis and I enabled the Z-Optimize feature as well. Worked great! Then I manually adjusted my Z height for the veneer I was cutting. But when I went to cut, the normal recipe I use did not even come close to cutting through the veneer and the burn line thickness was huge. Re measured the Z height manually, and I was way off. I Thought I must have bump the button on my boss by accident, so I manually re-adjusted Z and re-ran. Same problem. Then double checked all my settings, re-downloaded the job to the laser, re-adjusted Z manually and re-ran. Same problem! Then I remembered I did not disable the “Enable Z Height” in the general settings. Once I did this everything worked great. Went back and looked at my settings for my cut and the z-offset was disabled in my cut.
So the question is, why does enabling the “Enable Z Height”, cause the job being downloaded to the laser to change the Z-Height even though my cut is not using this feature?
