25 minutes of accumulated knowledge about XATC! I’m proud to present my longest video in the history about CNC and the simplest automatic tool changer.

Wow. Very long detailed video but you covered everything. That macro is really involved. You should make a nice widget for that. I feel like Arthur’s delrin approach can work. I really want my own auto tool changer so this is a huge step forward. I will reiterate that your rotation technique is pure brilliance and I think the entire rest of the CNC world is going to copy your idea.
Wow, thank you @jlauer . You know I’m a lazy software developer and i love simple solutions. 
to make a XATC widget is an option, but i think for the first time it’s enough to have an macro but please send me your ideas and maybe we can create a widget together.
