I don't know how 3.8 (needed for the ATC) does on Win 10. I'm running Windows 7 without problems other than occasional brain farts by the control software. The one I can't seem to resolved is after I do a C3 to zero all three axis with the proximity switches, if I move the spindle the slightest amount in an X or Y direction, the interface goes into a very weird slow motion and I have to use task manger to shut it down and restart it. SB gave me something to try and I'm going to try it.

Another thing with the ATC, if you use boring bits (they have a brad point) you will not get accurate depth holes because the hole you drill are only as deep as the cutting part of the bit. The brad point extends down below the cutting part. With some of my boring bits, it can be up to a millimeter or so difference. Ryan gave some things to try and trick the machine by adjusting the ZZero location for my boring bits. I'll see if it works.
