Jog the table at 250ipm to each side and verify that the limit switches are working properly.
Also, make sure that the table does not exceed its travel and crash.

Z-Axis Limit Switch-Stop Installation & Adjustment
The limit switch-stops for the Z-axis are mounted on the side of the bed at the headstock side and
attached by a bracket to the tailstock for the positive direction. Each limit switch-stop must be set
to a specific distance from the headstock and tailstock to maximize travel and simultaneously
prevent serious damage to the machine in the event of a crash. The limit switch bracket and stops
contains slotted holes, which allow for side-to-side positioning adjustments of the limit switch
assembly.
Procedure for setting Z limit switch:
1.
Slowly move the carriage to the front of the spindle with the handwheel until you are
approximately ¾” from the spindle.
CAUTION!
The limit switch must be triggered a minimum of ½” before the machine reaches its
travel limits in both directions. This allows sufficient room for the servomotors to stop
when the limit switch is hit at 250 ipm.
2.
Lock the stop in place and make sure when you hit the stop the switch is triggered and the
carriage comes to rest before hitting the spindle. Make sure you have adjusted the stop far
enough away to prevent a crash.
WARNING!
The Z-axis limit switch at the headstock end is set to prevent crashes into the spindle.
It is not adjusted for the various chuck or collet closer combinations.
3.
Perform a similar adjustment at the tailstock end of the bed. Make sure the carriage does not
hit the tailstock when the limit switch is triggered at maximum feedrate. At the tailstock end
there is slight adjustment up and down and more adjustment side to side.
