I don't need the electrics yet - not for a month or so. Need to finish the machine first.

That's a kind offer thankyou - but am I missing something then with this sort of thing?:

600W 60V 10A Switching Power Supply With Current Control Charger LED CCTV UKD | eBay

I've read that the back EMF of the steppers means you need to overspec the current of the SMPS - is that where the above would limit the performance of the 80V driver setup over the linear 600VA type?

As for mains there are just too many risks for me. Not only the first switch on, but later on with perhaps a poor earth or even a fire. I need something which has been built, tested and warranted so that I can get on with the bit I enjoy which is the Engineering and machining.

Thanks
