I tried looking through past posts, but didn’t see if anyone had tried investigating the possibility of modifying the crumb tray to serve as a vacuum table. Per prior recommendations, I’ve been using a Seklema mat to cut intricate designs in card stock but i find that I have a few different problems with it:
- the cutout pieces of the paper get left behind when you remove the finished product, and they are a pain to get off of the Seklema mat. I am using a small metal putty knife, but there are lots of cut out parts in my design.
- when I go to scrape off the scrap bits, the Seklema mat (or the crumb tray) inevitably slides to one side or the other. This makes it difficult to line up the next job against my reference marks on the mat.
So I thought a vacuum table of some sort that you could switch on and off would be a good way to keep the small bits of paper from blowing around and not require scraping at the end. The best bet might be to use a small venturi vacuum pump inside the glowforge with a skinny compressed air tube going into the pass through slot. Maybe there is another way to do it?
I also see on sites like instructables the idea of making an MDF vacuum table with little laser cut holes in the top surface. That would essentially require replacing the crumb tray, but you might be able to fit in a vacuum apparatus that would do the trick? Maybe another approach would be to have an external vacuum pump but have the discharge line also be within the glowforge enclosure so you are not sucking out fumes through the pump into the room?
