I would like an option for exponential spacing in material tests

[ClayJar (Nathaniel Klumb)]

The first replies seem to have missed the important part of your post (which is only in the topic, not the body): in material tests.

Spacing the values as the same multiple between steps, e.g. 100, 200, 400, 800, 1600,…, is called logarithmic spacing and is certainly more useful than LightBurn’s current linear spacing, e.g. 100, 200, 300,…, in many real-world scenarios.

I wrote up a whole post about how logarithmic spacing would be extremely helpful in material tests. Alas, I got no traction (or any official response) when last I tried to put forth this suggestion, but I still wholeheartedly support it for obvious mathematical reasons. For reference, here is my now-locked thread from November 2024:

Logarithmic Material Test (suggestion posted)

So, as I was working on frying more rocks, I found myself with some that just didn’t behave nicely on the fiber laser. My usual settings which work like a charm on slate or some black landscaping rocks just turned the surface to grainy marshmallow with terrible resolution and texture. I’m going to need to hunt through the entire parameter space of my laser to see if anything gives me some kind or other of interesting or useful results. It occurred to me that one small option added to the Ligh…

I would gladly resume my crusade for this obviously useful feature if there’s anyone to crusade with, so why don’t we see if maybe we can get at least enough traction to be noticed this time.
