Spindle / VFD options
The BOM spreadsheet groups optional 110 V / 220 V and 1.5 kW / 2.2 kW spindle stacks under separate headings. Use the Electronics table above for a default 110 V 1.5 kW VFD and spindle pairing, then adjust PSU, breaker, and contactor ratings for your chosen stack.
110 V 2.2 kW spindle
Most domestic 110 V circuits can only just supply a 2.2 kW spindle. We do not recommend this without a dedicated circuit.
