    Hi, I am looking at buying a 24v psu to run the safety / emergency circuit on my cnc router. Any recommendations? There's loads on eBay but what is the correct amp to go for?

    Same question for the 5v supply for the bob.

    I will be building my 70v psu to run the drivers / motors, is it worth making the 24v psu or isn't easier / more cost effective to buy one?

    The currents required for the breakout board, and 24V for other bits, are generally low so around an amp would be fine. It's best to work it out properly though - exactly what are you connecting to the 24V circuit? Relays?

    Thanks guys,
    The 24v system will be running 4 limit switches, 4 home switches (also acting as limit switches), 2 e-stops, running lamp and relays to cut the power to the 70v motor system.

    Should probably start a new post for this, but on my home made 70v psu / transformer should there be an earth wire connected or will it be earthed via the metal cabinet? What do people normally mount the components on to?
