Power Supplies

[komatias]

You could make your own powersupply. I am sure I saw the diagrams on here somewhere. 36V is a good place to start but you could push the Nema 23s to 48V if needed.

I'll be honest - building a power supply doesn't do it for me :) I'm just going to go for an off the shelf solution.

Is there a good reason that 2 power supplies were part of the kit?

[komatias]

yes, they are both 350W which would limit the current that the total of 4 motors would be able to draw at any given time.

You could probably buy the same powersupplies that were in the kit locally too.

That was my suspicion but I thought a better quality higher rated PSU might have sufficed as opposed to 2xcheaper units

[dcrowder]

OK from what I can gather I need around 11.5A from the power supply. I have a choice of 2x 350w 7.3A or 1 x 600w 12.5A.. What is my best option?

[komatias]

Which option works out cheaper?

[dcrowder]

£64 and £66 respectively

[komatias]

2 times the 350w would be my choice then ;)

Cheers! some things can look too obvious when you don't know :)

Hmmm.. are you sure ? $30 for me... http://www.aliexpress.com/item/600W-...8-830534792d55

I buy all my PSUs on AliExpress, they work great. (though my main PSU is a linear DIY)
