It's easy done when you start cnc machining (and from time to time when you've been doing it a while)
You need to get used to the machine and dial it in accordingly. You'll get there

I've been machining a number of parts recently and have supported the work piece using parallels (on their side) to lift it slightly off the bed. Then pushed a piece of thin MDF under the work to reduce the vibration. The parallels keep the work flat relative to the bed and you can cut at least 1.0mm through to make sure it is free without hitting the bed. I used tabs to hold it.

Just before each pass (when it is ramping down) I vacuum around the profile to clear the previous chips and give a bit of WD40 spray and repeat until done. I don't have a compressor so this is my way currently

Good luck with the fog buster development as I think that is a good long term approach
