5) Tighten the mounting screws securely. Re-connect the wire terminals to the proper
limit switch tabs. Replace the bumper and spring onto the threaded post.
6) Turn on the machine, and press the Enable button. If the Enable light does not
remain on when released, double check the wire terminals and connections to this
switch, and to the other 3 limit switches as well. If the initial limit switch damage was
caused by a mat jamming behind the gantry during cutting, one or both of the limit
switch wires may have been damaged as well, or the Y home sensor mat be
misaligned*.
7) Make a test cut to ensure
that the cutting head /
gantry do not hit the limit
switch during homing
movement. Make sure that
the limit switch bracket is in
line with the Y-gantry
beam. There should be
~1/8” of clearance between
the limit switch roller and
bearing cart edge when it
is in the “Home” position.

8) If the machine is unable to “Home” properly without hitting a limit switch, you must
move the switch and mounting bracket downward slightly. Use a 5mm Allen wrench
to slightly loosen the limit switch bracket. Make sure that the bearing cart will actuate
the switch approximately 1/8” below the home position by pushing downward on the
head after a mat cut is completed.
