Where is the fountain of knowledge for learning about CNC setups / understanding them

[Doddy]

If still no luck then I will purchase PSU I found this one https://www.ebay.co.uk/i/15261107092...9916224&crdt=0, are these safe to purchase or do i need to go to some specific website to avoid dodgy components?

VM (Max) for a TB6560 is 40V. I'd suggest a 36V PSU.
