Hi. I’m relatively a newbie, but I wanted to contribute.
I played around with setting for the Hobby Lobby leather pack and FINALLY found the sweet spot.
Thickness 0.2in
Speed 176
Power 100
2 passes
I’m posting pics to show the errors and the final! I put about an hour into trying to figure it out, plus reading through the posts.
Hope none of those pieces are chromium tanned–that releases toxic exhaust when lasered… But do keep in mind each hide may require different settings–etching is pretty easy, but different hides will often require different settings for cutting–but glad you’ve found what works well with the pack you have now! (And I keep meaning to make packs of my scraps to sell–I buy sides and sometimes full hides for the work I do, and have quite a pile of scrap I keep intending to package up!).
I also used these settings on the pack of leather bracelets I got today from Michaels and it cut nicely. I was having a hard time engraving using the material setting of thick leather so I changed it to unknown with the settings above to just cut shapes through it instead. Thanks!
