Like I'm gonna send it back - I know I'll love it.
I blow the ever lovin bejesus out of the machine after every single carve. And before every carve to make sure I got all i could. Very low pressure air, 30psi. Come to think of it sometimes it'll be around 35 wwhen I check my motorcycle tires and forget to dial it back but that's well within the spec of <80 per the maintenance page.
Just to throw another wrench in there for you, crank it up to 80 or 90 to clear the board sensor.
