Cycloidal drive 4th axis - fails & lessons learned

Being a perfectionist, I kept waiting for the perfect moment, perfect footage, perfect software...so I delayed this too much. Therefore, here it is, imperfect as it is!
Hopefully in the next videos, at least the sound will be much better! 😅

After those crashes, my machine is still fine, spindle has no runout, 4th axis, works perfect. The only victims are a few endmils, an ER16 collet and an ER16 nut.

For those interested in the post processor I'm using, here is the link to it:
