First, don’t even think about removing or blocking air assist! It’s a critical requirement for the optical system at the sharp end of our 'forges.
With that said, I’m sure I’m not alone amongst this talented group of creators in wondering if there could be a way to divert the airflow away from the workpiece without impacting those requirements. This would allow lightweight materials like paper/cardstock to be more easily cut (vs. engrave) without blowing material all over the machine.
I’m thinking specifically of a “shelf” that extends from the bottom of the vent to the “back” edge of the head itself.
