Yes, my black and white diagrm is absolutely correct.
I was staring at my router wires when I sketched it out.

If you want to keep your switch, just interrupt the black wire as it goes from the power cord inlet to the coil.
That's on the right side of my diagram.

But, the switch is a weak spot cause it has the wimpy little screw terminals and I doubt the contact points are as beefy as they should be for the large current that the motor can draw under full load.

I replaced the power cord cause it's 12 feet long and way too bulky.
All I needed was about 3ft of 2 conductor wire that was flexible and di not get in the way.
Also, the PID has screw terminal blocks for the Ac to the motor.
It just makes sense to ditch the big bulky power cord and run a nice clean and short dual conductor wire to the motor.

I have had the original Bosch power cord trip limit switches on my Y axis several times in the past and that sucks

Okay, I didn't see that one coming: the floppy power cord banging a limit switch...

OTOH, I coiled up the power cord into a bundle, and I just have Super-PID control the outlet it's plugged into, which rides along on top of my Z axis.

I had the idea that someday I might need to quick yank it off and I'd at least get the full-speed. I have to admit that I have not thought about, until just now, the fact that I will need to coil up the long sensor cord if I ever do it (it terminates in a Conxall fitting so I wouldn't have to lug the Super-PID box along at least).

Cheers, EL! Good helps for me.

Good luck with your machine
