Hope someone can offer a reason why this happens, and a solution?
It’s happened before, but today is best example:
Used some thick natural leather & proofgrade settings, etched a design and did cut outs (oval hair holders). Cut thru cleanly, and removed the cut out pieces, leaving the rest of the leather in place (held down w/ magnets on the edges).
Took the same etching & cutting and just shifted it over to another section of this leather (about 20-30 minutes, so plenty of cool down time). Etching OK, but Cut did not go thru the entire thickness–about 95%. Left the pieces in place on the bed.
Cleaned the head & optics, replaced those & even cleaned the camera.
Without moving the leather, changed the etched designs and moved the cut out shapes to another section of leather. Etching ok, cutting was only 50% of the thickness! (had to finish cuts with craft knife).
I suppose even though the thickness of this leather is the same, it could be pressed, so density could vary a bit and thus cuts? (this is “sole bend” leather). But i’d not expect it to progressively get worse with each run…
But I’ve encounted this with other leathers that I’ve used different settings for–get a few clean cuts and then it gets crappy…
Ideas/thoughts appreciated! Thanks!
