We've been running a 2004 mini in our shop, for about 2 years. The ATC is enclosed, unless it's changing tools, so no issues with chips on the holders. The only issue we have is the chips clog up the coolant drain holes, and it spills out on the floor, so if you're making a bunch of chips, don't leave it unattended for long. I don't know what the new ones have for a drain system, hopefully they have improved on it. Don't hang any fixtures, or vices too far off the back of the table, you can run it right into the enclosure, check your limits before you run. Good luck with it, happy milling
