The collet key is more like a nub now.
This was reported before, and I checked it and it was fine. I just checked it again, and it still seems fine. So maybe I don’t understand what you mean by collet key. I interpreted that as the internal spindle pin that orients the collet and keeps it from spinning when you put a tool on (as long as it’s in gear). What do you mean by “collet key”?
We are describing they same thing. If you compare it to the Rong Fu it’s much smaller.
