So here’s my problem…
I’ve got this 3/4" acrylic. I can get through it pretty cleanly now. Obviously I’ve had to remove the tray to cut this stuff. And that’s fine. But I can only get through it cleanly if there’s nothing underneath it. So I’ve cut through with the material basically floating in mid air. Even had to remove the masking or else it catches fire and either burns or smoke stains the acrylic. And that’s okay, too. There’s no burning or smoke stain with the masking removed. BUT! Now I need to cut then flip the object to do the other side. So I need to use the surrounding material as a jig. I cut the shape, remove it from the rest of the material with tape, then flip it and put it back into its own hole to do the other side. But now I have to have something underneath the hole (because material can’t actually hover in mid air). So I used wood. Well, the wood burned and smoke stained the hell out of the acrylic.
So! Either I need another way to do this, or I need to support the acrylic with something that will not burn and will not flash back onto the acrylic.
