If you have the full kit version of the WorkBee, please complete Step 4 of https://learn.ooznest.co.uk/Guide/4.+Limit+Switch+Assembly+&+Mounting/90?lang=en#s422.

First attach the bottom right wheel set - insert a M5-Low-Profile-60mm bolt through the X-Plate-Front through the side with the insets. On to this, add an Eccentric Spacer-6mm, Precision-Shim, Solid-V-Wheel-Xtreme-Assembly, Aluminium Spacer 9mm, Solid-V-Wheel-Xtreme-Assembly, Precision Shim, and an Eccentric-Spacer 6mm in this order.

Next add the X-Plate-Back-Assembly onto the top of this assemblage, add a Precision-Shim and then slightly thread on a M5-Nyloc-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on either the X-Plate-Front or X Plate-Back-Assembly (depending on which side it is on).

Repeat for the other wheel set on the bottom row corner.

Repeat for the 2 wheel sets on the top row, however for these sets use Aluminium-Spacer-6mms instead of Eccentric-Spacer-6mms.

Once all of the wheels are attached the M5-Nyloc-Nuts can be tightened down. Ensure that the Solid-V-Xtreme-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’.

In the same method as the Y-Plates, using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximizes the gap between the top and bottom row of wheels.
