Use a small vortex separator with a 5 gallon bucket and the suction ( dust) side connected to your cnc machine . Use any vacuum source. I cut the top of the bucket with my xl. Works extremely well, keeps the majority of the debrie in the bucket to allow for ease of empty. Greatly improves dust capture with a hepa filter in your vac. I bought the small vortex off Amazon. $30, but China has them at less cost. Tom
The Dustopper is another popular and affordable option, or one can make one’s own, or make a Thien Baffle:
Perhaps “Made In USA” should enter into the selection process.
