I am re-wiring my machine to it's (semi)final configuration. During this I am adding a charge pump and spindle control from Cnc4Pc.
The wiring diagram for the charge pump:

shows an external enable switch as well as an E-Stop.
Is this external pushbutton enable switch really necessary and can I just wire it out of the circuit?
Thanks,
