I confess I’m a bit of a neat freak when it comes to cable management. I had thought of a tutorial thread, but given that my build is endless and my first effort, was a bit embarrassed at the prospect of teaching others how to suck eggs!
I lay the wiring out a couple of times as though I’m building a vehicle loom.
Start with the end furthest from your controller, plug everything in step by step and bundle it temporarily with zip ties or a bit of tape just to keep it tidy. Work your way through every wire until you end up with a bit of a mash of loopy bits at the board - that will make it easy to shorten the wires later.
You might get an idea of that here: (sadly there’s a lot of nonsense to go through but you might glean something!)
Once you’ve done that - put the loom where it will end up and make sure that you have enough slack to plug everything in.
Pull it all out - I like to use automotive loom tape (fluff tape) to keep it all together permanently so I tape it, then when I finally have to I cut everything to length. If at some stage I want to make the table wider, I’ll just make two little extension cords for the bits on the “opposite” side of the table, and the board side will stay put. Not sure how clear that is
if you poke around starting at this post and the one that follows you might find some useful ideas. LowRider 2 - Long time coming - (Australia) - #131 by bitingmidge
