to adjust the y-axis leadscrew:
1. locate the adjuster midway along the
y-access leadscrew, inside the base. this
adjuster can be accessed by reaching under
the way cover just behind the table.
2. tighten the adjustment screw and test the
adjustment in the same manner as you did for
the X-axis leadscrew.
leadscrew backlash
When you turn the handwheels to adjust the posi-
tion of the table, you will notice slight play (back-
lash) in the handwheel before the table begins to
move. if this play is greater than 0.008" (measured
with the dial at the base of each handwheel), then
you will need to adjust the leadscrews.
Make adjustments in small increments. over-
tightening to attempt to reduce backlash to less
than 0.003" is impractical and will add unneces-
sary wear to both the leadscrews and the adjust-
ers.
