As I say - handy-ish - as in slightly less clicks
I have to jog my edge finder over 0.1” to zero, so in jog step that is 2 x 1mm, 2 x 0.25, 2 x 0.025 - easy to remember… That gets me 2.55 mm as opposed to 2.54mm. If I can get to 0.01mm or 0.0004” accuracy on machining thats a pretty good day.
To get to 0.1” in the previous scheme it was 2 x 1mm, 5 x 0.1mm, 4 x 0.01mm. Not the end of the earth to be sure, just a few more clicks.
As I mentioned previously I would probably go back to 0.1 and 0.01 should I have the choice - but it would be more for mental comfort. I somewhat doubt I could eke much of a difference out of my less than perfect machining.
EDIT - pondering this some more it is actually not quite that simple as the jogs to get the edge finder onto the edge position also play a role in accuracy.
