Limit Switch Replacement (part #’s: Limit Switch, 12-818, Actuator, 12-819)
There are four (4) safety “Limit” switches on the F-6100, one for each edge of the cutting
board. The most frequently damaged of the four is the lower Y-axis switch, located on
the lower end of the Y-gantry, below and behind the cutting head. This procedure
explains replacement of this switch, since it is also the most difficult to access and
replace.
1) Press in the Emergency Stop knob, or turn off power to the F-6100 by shutting down
normally. Raise the cutting head upward 12-18” in order to access the lower Y-axis
limit switch. Remove the large spring and
urethane bumper from the threaded post
as well. Note the location and orientation
of the switch prior to removal.
2) Remove the wire terminals from the limit
switch tabs by pulling upward firmly. Do
NOT pull on the wire itself! (Note that one
of the tabs [center] is vacant) If one of the
tabs has broken off inside of a wire
terminal, it will need to be removed at this
time with needle-nose pliers or tweezers.
