The current VFD is 110V — you’d need a step-up transformer such as I am using for my Mafell spindle:
(but I’d suggest avoiding a transformer if at all possible, it’s heavy and expensive)
Carbide 3D has an 80mm spindle in development — no idea on availability, or its power requirements, but it would be a nice upgrade, and it might be that it would be friendlier to 220V locales.
A Makita RT0700 would be a drop-in replacement while you’re waiting though.
