Here’s a test I just did on 3mm leather. Settings were 6mA on the dial, 500mm/s engrave speed, 1 pixel steps.
Obviously it doesn’t engrave that quickly though. Took more than 10 minutes to complete the project. Didn’t time exactly.
Very neat. I had some results markibg on the inside of some soft 1mm scraps and is cut quite cleanly in the outside of the same but I didn’t take the speed/power settings.
I’d like to be able to cut small patterns to stitch together for 3d keyrings or wallets etc.
Hey @Yuusuf_Sallahuddin_Y , do you use the laser to cut leather as well, or just engrave it and cut using scissors or … ?
@Ashley_M_Kirchner_No Hi Ashley. I have just purchased this laser so still learning how to use it properly. So far I just did the engraving with the laser & then cut the leather with a Stanley/craft knife & punched the holes with my hole punches.
I intend to use the laser to cut the leather also in future (once I figure out the correct settings).
@Peter Yeah I have been keeping track of speed/power settings as I go to hopefully create a bit of a guide for me in future (also for others who are interested). That way when I switch materials I will know what settings to use 
It’s a good work.
It will be usefull to create a shared document with Power and Speed settings for every type of material, divided in cut and engrave.
+Ashley M. Kirchner : in the past I tried to cut leather with laser but it didn’t work well… so I only print on leather
@Alessandro_Milano That’s very true. So far I haven’t tried many settings, but have been keeping track of it. Maybe an option would be a Dropbox collaborated Excel spreadsheet or something.
I’ve also found so far that cutting leather is very difficult (even at full power with 30mm/s cut speed it only 90% cuts through 3mm leather & makes a hell of a mess with soot everywhere). I’d be interested to test cutting leather whilst it is damp (not dripping). Might give some different results.
You may try wiping it lightly with neatsfoot oil. you may get a darker mark with less power and less actual burning.
I’ve done the neatsfoot thing using a burning iron and it works much better than dry. Hard to say how the laser will react, but I’d try it on a piece of scrap.
On the water, it’s worth a try, but I’m betting it just makes it harder to mark, the flash steam probably will eat up the energy without a color change.
Good Luck!
Scott
@Scott_Marshall Thanks Scott. That’s an interesting idea. Will have to grab some neatsfoot oil & give it a try.
