Hi guys, just going through the electronics phase and I have a question or two regarding screening of cables from control box to steppers and wire gauge size.
I'm running 570oz steppers as per Hoss's recommendation on my BF20 and was wondering what is the wire size needed from control box to the stepper. From what I've read 22 awg will handle 7 amps as chassis wirining (not bundled) and most catalogues quote 22awg 4 core bundles at 4.5amps or so. Will this be ok ? I can't see the longest cable being more than 5 odd feet long, ok maybe 6.
As for screening, is this absolutley neccessary ? I can see the pluses or screening, but has\is\does anyone use unscreened ?
Cheers
Rob
