    Re: What is Tinned Copper Wire?

    Thanks for your time, looks like it's not a good idea to buy cables online unless I know the source which I don't. Will try to find locally even in another town.

    Re: Reliable CNC Electronics Parts Supplier

    Forgot to mention the set came with 2 PSU each 48VDC, 7.3A. Why supply 2 PSU instead of 1 48VDC 12A? Is it less expensive or perhaps another reason?
