So when I do build my CNC router / mill I want to make sure I use a spindle / tooling combo that I can add a automatic quick change at a later date.

I have seen the Surline setup with the automatic release etc and I really like that Idea however I just feel that I will need something larger..

What options do I have... I have not personally used anything with a cat40 setup however im guessing that may be too big...

Any thoughts
