Vacuum Table

I was wondering if anyone had any secrets or input into being able to hold PETG or Lexan sheets to a CNC router table. I am running a KOMO MACH II router with a very good vacuum pump and have no issues at all holding MDF and other woods but I am having a real hard time holding plastics to the table. They lift off of the table with hardly any effort and move around when being machined. Any input would be appreciated.

Thx

Mark try the newsprint and see if it helps, it won't cost you much to do a test.

I apologize if I am stating the obvious, but make sure you are covering whatever part of the vacuum table, or zone, that is not being covered by the sheet. think I heard that vacuum can wander 2-3" in the mdf spoilboard past the sheet being held...
