1)
Remove the print board.
2)
Visually locate the ends of the red thumbscrews in the print board plate.
3)
Tighten all three red thumbscrews until they are flush with top side of the print board plate.
4)
Loosen each red thumbscrew 1 ½ turns. Confirm that each screw is recessed the same amount
below the surface of the print board plate.
NOTE
: If you are having difficulty determining how
much to turn the red thumbscrews, re-tighten all three red thumbscrews until they are flush with
the top of the print board plate, then place a mark on the right side of each red thumbscrew.
5)
Grab the print board plate and gently wiggle it up-and-down and back-and-forth to make sure
the wave springs are properly seated in the print board spacer, and to check for any loose screws
missed during assembly. Tighten any screws that feel loose.
6)
Install the print board by pressing it firmly into the rear print board clamps, then press the front
board clamp firmly against the print board, and finally secure the front print board clamp by
tightening the blue thumb screw located below the print board.
7)
Loosen the Z-axis end stop screw so that the end of the screw extends no more than ½” from the
bottom side of the top plate.
8)
Place a business card or index card (approximately 0.2mm) on the print board.
9)
Move the hot end and the print board so that the hot end is located directly over the center of the
print board. Using the Z-axis knob, lift the print board until the card is just slightly trapped by the
hot end. The card should be moveable with only slight resistance.
NOTE
: Try to not press down
on the print board when moving the card as this will make the gap between the hot end and the
print board appear larger than it is. (If the Z-axis end stop screw prevents you from lifting the
print board high enough, go back and redo Step 7 above.)
10)
While holding the Z-axis knob, hand tighten the yellow Z-axis lock thumbscrew to lock the print
board so it can’t move up or down along the Z-axis.
