Attaching the Recoat Mold Assembly

Make sure that the base plate and bottom of the mold assembly are cleaned of any dirt particles. Insert the pin
assembly by inserting the long end into the recoat mold assembly. Verify that the pin assembly moves up and
down freely.
Placing the Recoat Mold
Plug the ribbon cable connector that emerges from the center slot into the bottom of the LED board on the
underside of the mold. Lower the assembly straight down, making sure the pin assembly enters through the
correct hole, and attach the recoat mold assembly using five of the screws from the attached bag. Lightly tighten
two diagonal screws; leave the rest loose. The screws need to be somewhat loose to allow for adjustment of the
recoat assembly. Open the recoat station top and the tops of the fiber holding blocks. Clamp a length of coated
fiber between the holding blocks so that the fiber is under slight tension. (A fiber nominally smaller than that of the
diameter of the recoat mold should be used.) Using a 10X magnifying loupe, view the fiber straight down at the
right-hand edge of recoat station, as shown below. Adjust the recoat assembly such that the fiber is centered in
the bottom recoat groove. Repeat this procedure while viewing the fiber at the left edge of the recoat station.
Tighten the recoat flange screws and re-check the fiber alignment.
