position of the holes marked (A) being
slightly left of center will help you orient
the plate properly. The Z Axis plate was
designed to accommodate some of the
most popular choices in hobby CNC.
Hopefully, you’ve already se
lected the
router/spindle and mount combination
that you wish to use. See
www.millrightcnc.com/FAQ
for
more info
on the compatible spindles and mounts if
you don’t already have one. We have also
included some dimensional information
about the mounting holes for those
interested in making their own mount or
confirming fitment of available mounts.
The hardware used in each hole is as
follows:
Each one of these will be installed such that the head of the
screw or bolt is visible as you view the Z Axis Bearing Plate in
this orientation.
A:
M5x30 - Belt Idler
B:
M4x10
–
Bearing Block
C:
M4x14
–
Bearing Block / Spring Stud Bracket
We will first assemble the idler bearings on your Z Axis plate.
Each idler is made of two 625 bearings, so go ahead and grab
four 625 bearings, two M5x30 bolts, 4 M5 flat washers, two
10mm long aluminum spacers, and two M5 Nylock nuts.
TAKE NOTE THAT THE ALUMINUM SPACERS USED HERE ARE
LONGER THAN THE ALUMINUM SPACERS USED WITH THE
NON-ADJUSTABLE V WHEELS. Slide an M5 washer onto the
M5x30 bolt and put the bolt through one of the holes
labelled with (A) in the above diagram. You should insert the
bolt through the hole when looking at the Z Axis Plate as
shown in the diagram.
Be careful not to build things on the wrong side. Now, slide
the 10mm aluminum spacer on the bolt threads and butt it
up against the back side of the Z Axis Plate. Put on a 625
