One step forward, one step back. I got everything re-installed and my inner rails are very close to parallel to the outer ones now. When I was re-doing the wiring I noticed that on one of the Y harnesses the green wire had 2 bad nicks in it (I could see the wire). I tried to just tape it, but the servo sounds terrible when running. I switched cables with the other axis, and yep, it runs smooth. Grrrr. I am finished for the night but tomorrow will see if I can patch it up, otherwise it looks like I am in the market for a new Y harness.
