I have a 4'x8' router with a gridded phenolic table. 6 chambers, each chamber goes down the length of the table. You can see the pic for the specs of the vacuum we have attached. I have tried with both standard MDF and ultralight MDF (1" thickness) and I can't get good vacuum through it. Edges are sealed with 2 layers of latex paint, both sides are surfaced and am currently taking off layer by layer seeing if a thinner top with help.
Good vacuum to me is something that isn't easy to lift, while you can't slide anything on the mdf you can lift it up easily. When I vacuum directly to the table, its stuck like a sheep's head in barbed-wire. Is there any reason I couldn't cut directly on the table? I am onion skinning all my pieces (Acrylic with masking) so shouldn't be cutting into the gasket or the table.
If I add a bunch of 1/8" - 1/4" holes along the table will that help pass the air through? Granted my mdf sheet is 97*49 while my plastic sheets are 48*96 so I need to find a way to seal around those edges or just trim the mdf to size.
Pretty new to cnc, machine setup is taking a long time and I liked to get to production soon. Just looking for some guidance.
Thanks,
