In all honesty, if you've got a compressor, get a vacuum table.

Small vacuum table kits can be had for not that much money - https://vacuumtables.co.uk/diy-cnc-kits
Or if you have some other method of generating the required vacuum, the basic tables aren't expensive - https://vacuumtables.co.uk/vacuum-ta...rking/r-series

I've got 3015 R and 4030 RAL table from that website, and they do the job. I was surprised by how little air they actually use. My 3HP compressor runs less than 50% of the time when using either of the tables.
