DIY cnc power supply .

[sizala]

hello guyz ,
i have ordered a TB6560 board from ebay.. it will be in my hands in 2-3 days.
so my problem is = how to make a good power supply for that board? i found from lots of online posts that the ebay TB6560 board can run well at 24V. so i am going to make a 24V power supply .
i want to use 10amp supply to be sure that i have enough power.

my problem is = to have a good power supply i need to use atlist 22000uF cap. but that cap is not available in my city. so i am planing to use 50V 470uF X 50 caps = 23500uf.
so will it work? i mean does that make any difference if i use a single big cap or 50 small caps?

and also = i never made a power supply before , so plz guys provide me a good diagram of power supply for my home made 3axis cnc mill.

plz see the image. i am thinking to do something like that. and which type of cap to use = blue cap, or black cap, or the grean(isolated cap)? which on is better for me?

I would try to find good size capacitors on Ebay.

50 capacitor for a power supply is not something to save space in a cabinet

Capacitor is not an exact science in power supply, it can vary a lot and every body will made things different.

i brought this capacitor...will it work for me? it is a 10000mfd 63v i will use 3 cap like that..will it work?..plz see the image

Yes it will work, just be sure to place it correctly, + with + and - with -

Instead of one capacitor, place 3 in parallel, meaning all + together and all minus together(schematic show only one)


Or just buy that kind of power supply, cheap and reliable.
