I will note that the expense and complexity of automatic tool changing was what drove me to select a Mafell FM 1000 WS (didn’t get the PV version because it would have required working out how to connect to the BitRunner adapter and have that handle 220V while still working w/ my dust extractor):
it was pretty straight-forward:
- mount using mounting plate
- make different thickness dust shoe plates for different lengths of endmill stickout
- connect to 110V–220V step-up transformer
- plug in to BitRunner
- plug in to power sensing outlet on dust extractor
While not automatic, tool changes are quick and just about effortless, and complex test jobs no longer have me feeling as if I’m spending more time wrenching than cutting.
