Replacing The A Axis Limit Switch
If the Operator has determined the A axis limit switch is not functioning, replacement of the
switch will require removal of the Toolhead. Bend-Tech recommends powering down the
machine any time the Operator is performing a major service to one or more of its components.
1. Remove the tensioning springs on each side of the Toolhead. The tensioning springs are
located on the backside of the Toolhead. Using a pliers, grab the bottom loop on each
spring and pull down on the spring to release the loop from the tensioning spring mount.
2. Using the same method, remove the Engraver retraction spring at the front of the Toolhead.
3.
Using a 3/16 in. Allen wrench, loosen the Torch mounting collar and remove the Torch wand.
Set the Torch wand out of the way in a safe position where it will not fall or get damaged.
4. With the tensioning springs removed, the Toolhead will be resting on the Engraver
tensioning spring mount at the top of the Toolhead. Place a ⅜ in. wrench on the nut on the
backside of the Engraver tensioning spring. Holding the nut secure with the ⅜ in. wrench,
use a ⅛ in. Allen wrench to remove the Engraver tensioning spring mounting screw and
mount. Hold the Toolhead in place while removing the Engraver tensioning spring mount.
5. Using a 5/32 in. Allen wrench, remove the two Toolhead mounting screws located at the
center of the Toolhead assembly. Bend-Tech recommends enlisting a helper to secure the
Toolhead during this process.
6. Use a Phillips screwdriver to remove the two A axis limit switch mounting screws.
7. Disconnect the spade connectors that connect the sensor to the machine. Note the location
of the wires before disconnecting them so they can be placed in the same position on the
new sensor.
8. Using the two Phillips head screws, mount the new sensor to the Toolhead. Install the
spade connectors into the locations noted in Step 7.
9. Reverse this process to reassemble the Toolhead.
