I am at a point, where pretty much everything mechanic is finished.
I am building my CNC in garage, and I only just realised that there is no earth wire coming from electric box, there are only phase and neutral. Now I am quite stuck, do I have to dig in some peace of metal (quite impossible in that location), or do I just leave earth wires from spindle and PSUs untouched? Would it cause safety issues? The thing I am struggling the most, is where to connect common earth from all of the shields to? Any ideas how to approach this?
On the side note - how big fuses are you using for VFD+2.2kw Spindle and motors/drivers? I am planning to go 15A for spindle and 10A for drivers/steppers?
