Thought I would share my testing results using engravable leatherette from JDS Industries (unfortunately you need an actual business to be a customer of theirs).
@jbv got us started with this post: https://community.glowforge.com/t/initial-settings-for-jds-engravable-leatherette/39892
For all tests, I chose medium PG leather just to select a material and then, importantly, used the new SET FOCUS feature.
Engraving at 1000 speed/12 power/340 lpi worked perfectly on leatherette sheet stock and this keychain:
But those settings, interestingly, were too much on this one. The only thing I can think of is the leatherette appears to be thinner on this bottle opener, or maybe the “rustic” color is just different than the teal:
[EDIT:] The “rustic” color works beautifully if you drop the power to 10.
Then I ran tests for scoring and cutting.
Scoring is really finicky, and it’s hard to keep the laser start and stop points from burning all the way through. Plus it just doesn’t look good anyway. So I don’t plan to score this material.
Cutting worked great at 150 speed and 16 power.
