Yeah, I haven’t played with that feature yet and it would be wonderful, except I use an adjustable height nozzle/lens.
When I was using the camera after calibration I noticed a fair bit of misalignment due to shifting the focus height higher with the nozzle tube adjustment.
I have plans to try doing the calibration at different heights and export/import them into a folder to combat this but it a bit more hassle than I am prepared for currently.
The other option I am considering is making a lower section for my custom laser machine that would house a stepper driven bed. With that I could always lower my material surface to the calibration height and enjoy the benefits that provides.
Right now the adjustable nozzle is so fast and simple I haven’t had much need of the camera at all.
