fins saw it right away as I just posted this project I did doing a “deep” cut through a 0.5mm utility knife blade. It’s pretty cool to see what you can do.
It looks like the depth of focus was about at its limit, 0.5mm thick. It would cut without lowering the Z. I did lower the Z in some runs, but it didn’t seem to be necessary. It did seem like this was the limit of how far it could go without lowering the Z further.
