    Yep buy a 24V and use it to power relays etc that you'll need to safely control other things like vacuums or spindles, coffee machine etc
    Also use it to run thru E-stop and limit switchs for a very safe control system with better immunity from noise.!

    Don't need high amps 3-5 will be plenty and cheap enough on ebay.

    Thanks for clarifying that. I have a 2A 24V PSU which I was going to use for the main control, safety circuits and cooling fans. Will have to re-calculate my total consumption and see if the 2A will be enough. I guess the other option is to use one of the spare 12V from the PC power supply?
