Polar Alignment
My 10" LX200 is mounted on a Super Wedge that has been
slightly modified.
Thrust and nylon bearings were added plus grease on all moving components.
A Scope Saver is mounted in between the wedge and the tripod.

I use drift alignment procedures for precision adjustment after
initial polar alignment.
Astronomer's Control Panel has a very good procedure that is
better than the one
in the Meade manual. After this initial step I drift align.
Drift Alignment
Azimuth Adjustment-Side Knob
Find a star near the meridian and with an 12mm or better
illuminated reticle watch for drift.
Adjust reticle until star moves parallel to the left right and
up down lines using NSEW on keypad.
If the alignment is off the star will either drift up or down.
Don't worry about drift in R.A.
If the star moves up turn the right knob counter clockwise
(looking at scope power panel).

If the star moves down turn the right knob clockwise.
Altitude Adjustment-Back Knob
Now move the scope to within10 degrees of the eastern horizon.
Same as above, watch for star drift up or down that will at this
angle be in the R.A. lines.
Move back knob counter or clockwise to keep star centered in
cross hairs.
New T-Block eliminates backlash 
Once complete slew back to the meridian and recheck for any
movement.
After the star stays in the crosshairs for 5 minutes a good
polar alignment is achieved.
Repeat until the star has no vertical or horizontal
movement.
Now you can perform P.E.C. training. I have tried manual and
auto guide methods and
have found the manually entered method to work better although
some have had success with the latter.
