Russ made a tool to measure the best focal distance a few year back which I have used since then.

He seems to be using a different system now which involves a series of burn marks where the head lifts at 1mm intervals between burns which I have been meaning to figure out- if he has mentioned how it is done, I missed it. In Lightburn I assume it involves different layers with Z offset?
