I have been using the built in Material Test with a Monport 60w Mopa on Stainless Steel.
Found some good results for colors and then transferred those results into a project layers.
But getting vastly different results, on the same sheet of material ..
Is there a way to create my own material test with ranges of power / freq etc ?
(Without having to create 30 squares and go through each one individually)
Yes.
No.
The Material Test usually fails to translate because the test square area does not match the engrave area. A larger area requires more total heat energy to anneal the metal to a specific temperature.
I get that, but the tests I have done are all on the same material, at the same size ..
The results from the Material Test, do not carry through to the Project results.
Which is why I need to make a custom test, so I can get “real” results ..
Hmmmm ..
Now that I think about it, is this why people use faster speeds with tighter line intervals ?
Looks like its time for some more testing …
Have you factored ambient temperature and air currents into your testing?
My aircon stays at the same temp all day throughout the house ..
There are no ‘air currents’ other than the gentle suction of the exhaust fan ..
So I would think, yes, factored
