Wiring home and limit switches

You don't need to use CY cable for your limits assuming it's a 24v circuit. I would use twin cable and bring them back to a junction box where you can series them up. If later on you want to change how they are connected then you won't need to rewire them, just change how they are connected in the junction box. The limits circuit is low current and low voltage so I plan to use twisted pair CAT5 cable, because it's twisted it is effective at screening out noise.

My only caution is that CAT5 cable tends to be single core and that would not be suitable for constant flexing. You would have to use the type suitable for patch cables. I wish I had thought of it, I have an oudle of it (15+ metres) and I bought cable from BRIMAL (Welcome to Brimal Components) They have a good range of interesting bits at keen prices.

Thanks guys. Just another stupid question: as the x axis is slaved do I only need limits on one side only or both. I have homes on both to ensure the gantry is squared.

Just one Side Dan. Think about having the Switch travel on the gantry with Triggers at each end to save on wiring and switches.
