was going to ask this in the DIY section since people over there seem to come up with ways to do tool changing..
In anycase hit the link to PCNC and found there link to 4 and 8 spot tool changers. Was curious about more details.. Think it's similar to another (can't remember the name) that had the tools clamp in and out but that one didn't use ER collets as it says this one does. (course I think ER16 don't go to 1/2" which would be a downer..
Anyway curious about more info on the system..
