Power supply understanding

[EddyCurrent]

Thanks Eddy.
Hopefully i've added the earthing point in the correct place now?

Like I said you didn't have to put the neutral to earth, some people do it others don't. In some cases where other equipment is connected you might have to put it to earth to get a common reference but in the case of just using stepper drivers it's not vital.

I'm going to put a 230v regulator before the transformer, either an AIO or just the chip on a circuit board with some caps, resistors and a heat sink. The reason I am doing this is because my mains electricity fluctuates. I've took 3 readings at different times and got 235V, 241v, and 248v, so much for the 230v switchover!

You probably won't need the regulator.

With this voltage regulation will I need the drive fuses?

Yes, the fuses are to protect the circuit from overload.

Without you and this forum I would still be trying to work out maximum step motor voltages.
Cheers, Mark

You are correct, I needed the forum myself when building my machine.
