The X-axis lock nut was found to be loose

During the Motor Coupler Centering of the X-Axis.

The X-axis lock nut was found to be loose.

The tab washer was unbent from the lock nut slot

In order to properly tighten the lock nut I purchased 2 P/N 30485

Spanner Wrench's from Tormach and 4 Tab Washers to have in stock

A friend suggested that I check to see if the coupling's were centered.
Thanks for the heads up Kaz. What follows is what I found.

This is the position of the X Axis Motor Coupling Before Centering

X and Y Axis Limit Switch Wiring

Wires at the X axis limit Switch

J2-1 is a RED wire at the X axis Switch

But at the terminal Block J2-1 is a BLACK wire

There is a splice of the X Axis Limit Switch in the Y axis Junction Box

As you can see J2-1 RED becomes J2-1 BLACK!

New Black and Yellow X Axis wires are run from the 

X Axis Switch back to the Terminal Block

New White and Yellow Y Axis wires are run from the 

Y Axis Switch back to the Terminal Block

Now the numbers and the colors

 for the Axis Limit Switches Match
