I ran a material test on my Commarker B4 30W. I got some really good colors at .0008 line interval but the line interval in the settings can’t go below .001.
Why can the material test run at a tighter line interval than the software allows?
The resolution of your Comaker appears to have a 0.01mm precision, so asking it to do 0.0008mm or smaller. That means a repeatable resolution.
I have an F100mm lens for mine that’s a very small spot size of ~12 microns or 0.012mm. If I run that at an interval of 0.0008mm I’d make 15 passes over the same area.. This chart, from Cloudray, has spot sizes for different lens lengths.
What software allows you to use an interval of 0.0008mm?
One of the issues you’ll find, is you get that color varies with everything. Make it larger it won’t hit the desired temperature and you won’t get the color you expect.
Good luck
Thanks for all the info. I considered the machine wasn’t capable of a line interval less than .001 however lightburn’s material test did it.
So as I originally asked, why did the lightburn material test allow for .0007 or did it not truly hit that mark but claims it did.
My issue is I’ve found a blue that works at .001 and .002 but when I start creating the image, it ablates the steel but doesn’t always get the color. Some times it does on the diamond edges, some times in Cub Scouts, sometimes neither.
I’ve tried 0°, 90°, bi-directional on and off, cross hatch on and off, sub layers of different directions. Tried darker blue (.002) and sub layers of brighter blue (.001) and visa versa. So I tried tighter line interval and found this new blues but can’t test it further.
Most of the time it appears when trying additional passes or angles the first pass gets some color on and the second cleans it off while coloring the sections the first pass missed.
That’s a good question for the developers. I surely can’t help you much with the internal design of the software. You have a nice range of colors.
Maybe @Rick can give us an idea how it’s working at these low values.
Many of these machine can be asked to do something, it will if it can, but usually won’t tell you if it’s out of range. That’s the controller, how Lightburn handles it, I can’t say. You’ll just have to hang in there.
