in the R3 BOM there is a recommendation to use a 1.5kW VFD spindle. I have been searching through eBay mostly and I see plenty of options but they all seem to take 220v as input. Are there any VFD spindles out there that can operates on 110v? I will be cutting foam, aircraft plywood, G10 for the most part. Would a 12-48VDC spindle work for these materials?
