I read in the do not use the laser to cut sticker backed felt since the adhesive would eventually gum up the laser, Does this still apply? I have the pro version.
It depends what the adhesive and/or backing is made of.
Vapor from certain material (most significantly, chlorine, which is a primary component of adhesive vinyl) can seriously harm your machine. Even one cut could do permanent and irreversible damage.
Your best bet is to find the MSDS for the material in question.

This is the product I purchased and I’ve only scored it not cut it. https://www.amazon.com/dp/B07BGXW71Q?psc=1&ref=ppx_pop_dt_b_product_details
It depends on the individual product, but I really doubt this. I use an adhesive backed “felt” that is really polyester. The laser cuts a line through the felt that is roughly .008" wide. What used to occupy that .008" was polyester, the adhesive and the paper-based cover of the adhesive. All of that material is vaporized into various compounds and small particulates (collectively smoke.) All lasers have to be designed to work with smoke collecting on their parts. In order to gum up the laser it would need to make some very sticky smoke. From what little I know of adhesives I don’t see them vaporizing and then reforming into a glue. I also haven’t heard of this from any other source.

Interesting. The proofgrade veneer has a 3M adhesive backing, which is a very commonly used adhesive backing.
