E-Stop wiring

How should I wire my e-stops?





I believe my only options are:

1.) E-stop switch connected to the parallel port. [software polled,
TurboCNC]

2.) E-stop switch between the capacitor and the fuses. Star pattern
from e-stop, instead of the +'ve terminal on the CAP.

i. DC Capacitor +'ve

ii. E-stop

[Repeat below as many times as needed]

iii. Fuse

iv. Gecko Pin 2 (with 470 uF cap)

3.) E-stop switch between Gecko Pin 1 and the -'ve on the capacitor



What is the best option? And any reason for it?



I have a bleeder resister on the CAP.



I'd just like to know how others have setup their E-stops.



Thanks.
