Hello out there.

I am about to update a 3 axis mill with Rutex 90H drives, an opto
breakout board and mach2 operating system. I have some questions
which are:

1./ What is the most advisable way of wiring the E Stop ?

2./ How to wire the limit switches which are fitted one
per axis and still get back under power when tripped.
Will the co-ords be lost. The previous sytem retained the
co-ords but the servo power had to be reset after winding back

3./ Safe-ish way to wire spindle and suds etc without watchdog
type pump circuit.

4./ I have a VFD which I could fit for spindle control.
Is this worthwhile under program control if in fact there is no
auto-toolchange.
