3. Adjust both left- and right-hand macros as required. Save the files after making the appropriate changes.
In order for the changes to take effect, power to the system must be cycled off and on. This will cause the
new cleave macros to be uploaded.
4. Confirm that the fibers are now cleaving mid-range of the oscillation cycle. Re-adjust if necessary.
10.3.8 Rotate/Replace the Cleave Blade
If the cleave blade has already been shimmed up twice and needs further adjustment, it can be rotated 180° to
flip the bottom edge of the blade to the top. If the blade has already been flipped and shimmed twice, then a new
cleave blade must be installed. Either way, follow the instructions below:
1. Advance the cleave blade forward from its parked or "home" position. This can be achieved by sending
the command:
MOTORTO (11 -1000)
from the command line (note the negative sign on the motor position). Alternatively, assign the macro
"Service Cleave Blade.txt" to the user macro
menu bar, and then execute by clicking on the User Macro icon. This will advance the cleave blade up
approximately 45°, such that the set screw securing the blade is accessible on the left side of the cleave
blade arm as shown in Figure 65.
2. Loosen the cleave blade set screw using the 0.035" hex key. Note: one full turn counterclockwise is
sufficient.
3. If simply rotating the cleave blade, proceed to step 7, and follow instructions for rotating and aligning the
cleave blade.
4. If replacing the blade, push on the bottom of the blade shank, which is accessible through the hole in the
cleave blade arm. Push out the old blade sufficiently far such that it can be grabbed and removed with a
pair of tweezers.
5. Select a new cleave blade, and, with the protective plastic tube still in place over the front of the blade to
act as a handle, insert the shank of the blade as far as possible into the cleave arm.
6. Re-tighten the setscrew until it is just snug and remove the protective tube from the front of the blade,
exposing the diamond tip.
7. Check if the stainless steel cleave blade base is fully seated against the cleave arm and that the diamond
blade is oriented perfectly vertically. If required, loosen the setscrew and re-position the blade using a
pair of flat-tipped tweezers to rotate and seat the stainless steel base. Take great care not to touch the
diamond blade with the tweezers or any other hard objects or it will get damaged.
8. Tighten the setscrew and confirm the blade position.
9. Home the cleave blade by sending the command:
MOTORTO (11 0)

Do not push on the diamond tip of the cleave blade with your fingers or you will cut
yourself.
