@Jonathon Stepper cables are sorted, Thems the ones in the bags in the pic (lower left x 4) , Its more signal and power wire in the box joining the PMDX126 and bits together. So I take it, it doesn't matter too much whether or not soild core or multistrand for either Signal or power? if not Ace! less headaches.

I have a PMDX126, a 134 MOBO, and a 107 speed control board, so the wiring on those is pretty much plug and play with the 134 Mobo connecting the 126 BOB via ribbon cable, and the 107 is a daughter board mounted on the 126, so the wires in question would be any other wire from the BOB to power supply, etc.


Them thar's 940 oz nema 34's and the machine is going to be a 4x4 bed when its born.

@Jazz, Ahh Noise BAD, I see , So binning the contactor now I know what one is, for Power Isolation IE turning the machine on and offable, I do have a mains rated two pole switch that came with the kit, I take it that can be spliced into the power supply circuit without a relay.
and If I'm powering things like E stops, then from the 48v DC side, Relays?

Is it worth just bobbing into Maplins (insert cheaper shop here) and grabbing a few meters of bog standard non shielded 14 awg and 22 awg /metric equivalent, of various colours, I'm thinking I'll need some blue and brown, and maybe some earth for Power and black and white for signal?

looking online is where my brain pops.
What say you chaps?
