  1. Thank you Rob and EddyCurrent. I will have a look at NVR's and I didn't realise that I would need to a switch to reconnect the limit circuit to enable me to jog off from the error position. Am I correct in saying that the HG07 BOB will recognise a 0v or 5v line with a max 5mA? The HG07 data sheet says very little about the inputs.

    EddyCurrent, you mention that I have the proximity sensors wired correctly to a point! What do you mean by that?

    Is there a benefit to giving MACH3 a separate input for limits and emergency button, can MACH3 act differently? I suppose from my point of view I had the limit switches as just that, a last line of defence after soft limits, the emergency switch is a "oh my god" I am being eaten by the machine Stop everything NOW with no software involved.

    I wouldn't worry about the bob inputs just provide a 0 or 5v signal.

    I meant you have the correct coloured leads going to the right places i.e. brown + ,blue - ,black load

    Breakout board diagrams will generally show them using separate inputs, Mach3 has a dedicated E/Stop input.
    If you want the machine to do something different depending upon the emergency stop button being pressed or limits being hit then use different inputs, you can make Mach3 act differently. I think it's a matter of personal choice, for me I want the machine to do the same thing if either happens and I don't want to rely on software that's why mine is like this http://www.mycncuk.com/forums/router...html#post52213
