You just don't have enough fields for all the portable CNC tools I currently own personally:
2 MaxNC 15 mills with CNC 4th axis, touch plates and probe
1 MaxNC 10 mill with touch plate
2 MaxNC T2 lathes
1 Seig X2 with Hoss modifications
2 LPKF Protomat 90s circuit board mill / engraver
15 3D printers, including: 2 Up! Plus printers, 1 SoliDoodle 3 and lots of Prusa
2 ShopMaster mill/drill/lathes, one configured for CNC right now, the other manual but the retrofit is still there.
1 48" portable CNC router/plasma cutter custom table (the steel supports come out with the water trays and the table converts to hold a high speed 1/4" shank router with a SuperPID - custom job by an old friend very nicely done).
I personally own this stuff, fix it and acquired it all used. I have quite a few BobCAD/Mach3/FastCAD licenses floating around. I do some commercial work on them, but it's mostly side projects: enclosures, mounts, signs, letters, car parts...
Eventually this will all be moved from my home and various storage locations to a makerspace somewhere.
(When your house starts to look like Dean's on a smaller scale, you might want to reconsider your hobby. Many thanks to my extremely cool girlfriend with regards to my tools).
