Many thanks Clive
I am searching around in the hope of finding them a bit cheaper but at least i am on the right track!

You might find it cheaper to get multiple smaller caps, I got 4 x 4700uF ones for a few pounds each, just means more connections to make...
Also... what sort / size cable do people generally use for wiring coming from the psu to the stepper drives and wiring the power elements of the estop circuits bearing in mind I am using the CSMIO from cslabs so its all 24v in relation to the motion controller except the mains in
Just trying to get an idea of whats best to order in bulk
You want Tri rated for general single wire runs for power to steppers, relays etc like this. http://www.csecables.com/acatalog/Tr...l#aTri_2d0_2d5
For signal cables you want Shielded CY cables or like Clive says you can use twisted pair Cat5 but only use inside control panel not running to limits etc on machine as it's not really flexible enough. I tend to use Cat5 in box as theres less wires and one cable will provide for 2 drives.

Bear in mind the Csmio doesn't provide voltage from the I/O you have to feed it 24V +/- to each I/O so you'll need plenty of connections on the 24V rail or do some jumpering. Suggest you get some Din rail terminals with Jumper bars to create one Multi connector.
Thanks Clive and Dean.
That tri rated cable what size am I am looking at for the stepper power feeds?
Yes quite correct I should have said cat5 flexi as in the patch cable type. (although you can buy flexi by the roll). CliveQuote:

Aliexpress is your friend for cheap capacitors, and just about anything really:

You need to be wary of fakes - I got these as they were the cheapest at the time and they're fine. On the lower end of the tolerance but that's not a big deal for what we're doing.

This is how I've been using the capacitors:

It keeps things reasonably neat.
