Wow! Thanks, Tom! That is VERY useful to us hobby-folk!
Yeah, I watched a 4-quill CNC PCB-drill with "pods" change its own bits, and
all SEEMED to be fine, but I just could NOT help thinking, as I walked away,
"This CAN'T be so reliable ALL the time?!!!" GOOD to hear it isn't!
Interesting you say the quill motors are electric. I was told they are
PNEUMATIC, to run at 100,000 RPM! Hmmm...
