We recently had an issue where the vacuum pumps lose pressure partway through a sheet. Usually turning the dial on the CNC off and on again fixes it, so likely not a leak or a faulty vacuum pump. It goes from 20-25 HG to 0, so the router stops and we have to reset it. Does anyone know what this could be? Can't see any disconnected hoses or anything, thinking it could be a sensor/electronics issue or something... thanks in advance!!
Just to update, I think problem is the switch on the cnc because turning it off and then back on makes it work, as well as just pushing the dial in hard
