Just received the F1 Ultra two weeks ago and while working on hydbond leatherette I decided to try to cut the leatherette in the design of the logo. Each try I did while using blue light the cut was made through the leather but not the thin adhesive on the back. Should I try a setting using the fiber laser and if so what setting should I use.?

While using the blue light I tried different setting using a combination of 80% at a slower speed and then also tried using a faster speed of 70mm. I did try using a faster speed making 3 passes and It still did not cut the adhesive. All settings I used did cut through the leatherette. 

This is our first laser and I'm really enjoying it. Any advice would be appreciated .

Thanks!
