Flip the bed back over so the Y Axis Assembly is upside 
down. Using your hammer, tap the T-nuts into the 16 

holes labelled “A” in the above diagram.

 

 
 
 
 

 

Now find the Y Axis Belt Anchor Plate. Slide an M6 washer onto an M6x25 screw then put the 
bolt through the plate in the orientation shown below. If you were looking down at the plate 
in this orientation, you should see the bolt heads. In this orientation, the M6 screw needs to 
go through an M6 flat washer, through the plate, then through a split-lock washer, then 

secured with an M6 nut. Get a final tighten on the nuts now. These don’t screw to anything 

else, they just serve as studs to anchor the belt. 

 
 

Put the Y Belt Anchor Plate against the bed so the heads of 

the M6 bolts are laying inside the holes marked “D” in the 

center of the above picture. Line up the holes on the 
corners of the Y Belt Anchor Plate with the holes marked 

“B” that form a square around the holes marked “D.” Slide 
an M5 washer onto a 5/8” wood screw, then screw it into 

the bed in order to secure the Anchor Plate to the bed. DO 
NOT OVER-TORQUE THESE OR THE SCREW WILL RIP THE 

 

HOLE OUT. Pick one corner to start, and leave the screw 
a little loose. Line up the hole on the opposite corner, 
then screw it in. Put a final torque on the four wood 
screws once you have them all in. A contributor to this 

kit’s development has suggested inserting the s

crew 

fully, pulling it out, putting a couple drops of 

  

superglue (not included) in the hole, and 
immediately rethreading the screw in the 
hole. This is intended to prevent the screws 
from vibrating loose over time. 

 

You will now install the Bed onto the Y Axis 
Assembly. Orient the bed so that it holes are 
facing up, like in the diagram above. The holes 

designated as “C” above are recesses for the 

bolt heads of the V Wheel Kit bolts that are 
on the Y Axis Bearing plate. Flip the Y Axis
