I started out disliking the 0.25/0.025 increments but it is growing on me. It is handy-ish if you use Imperial tools (like my edge finder) but metric dimensions.
Would I go back if I had a choice? Probably just for that perception of increased accuracy feeling
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.
@PhilG There are plenty of counter-examples to your example. For most of my work I don’t need to jog with the 0.01 mm setting. But I do want precision at 0.1 mm resolution. So now I would have to switch resolutions a needless time to access the final 2 - 3 steps of 0.1 increments.
@bpedit - Absolutely there are different scenarios!
The example I gave is for my work flow - which is not everyones. If you have a different zeroing procedure that doesn’t involve an imperial tool the 0.25/0.025 increments add nothing as far as I can tell.
Right - after doing a pile of edge finding/middle finding/precision jogging this week I am changing from being OK with 0.25/0.025mm to intensely disliking it again. 0.1/0.01 jogging requires alot less brain math.
I cut mainly Aluminum and I can’t stand .025 vs .01 mm as I zero Z with a piece of paper and that extra .015 goes from a gap to pinching the paper so hard it cuts through every time. I only updated carbide motion because I installed an HDZ. If they don’t add it back I will reload an older build.
