Power supply and E-Stop question

I'm in the process of completely redoing the control wiring on my
CNC Bridgeport to incorporporate a keyboard emulator. I figured I
may as well re-examine everything I've done and tweak what I can.

1) My power supplies have bleeding resistors across the
capacitors. I was thinking of relocating the bleed resistor to a
N.C. set of contacts on the "stepper enable" relay with the other
side of contact going to ground. This would put the resistor between
the positive terminal of the capacitor and ground (negative of
capacitor already connected to ground) when the power supply is de-
energized and resistor would be ignored when power supply is working.

Is this a good or a bad idea? (if bad, why not)

2) On E-stop, I am currently cutting the A.C. power to my stepper
drive power supply. Should I change this to cutting power at the DC
sidee of the capaciter (I will need 3 relay contacts instead of 1)?

Thanks for the advice,
Jeff
