CNC router, not quite working right

The CNC router table is not producing a normal amount of vacuum pull on the wood piece being cut.

Mitch and I examined the table base. Very few holes were blocked, 99% were clear.
I examined the canister in front of the table vacuum pump and it wasn’t blocked. It actually had nothing inside.

There was a filter next to the canister that simply sat on top of some piece of the system.
That didn’t look quite right and it might be a place for the system to lose pressure.

Anyways, can someone who knows the system better take a look?

PS. I didn’t check out of the CnC system with my card last night so if someone gets this message today at MakerSpace please check in/out to secure the controller in the small cabinet. - Thanks
