z-axis
x-axis
y-axis
The diagram below shows the machine coordinate system of the LongMill. It’s able to move in its x, y, and
z-directions due to the rails and respective gantries it has on each of those axes. We’ll start by assembling
the xand zgantries which combine into a singular assembly; in the diagram these are coloured red and blue
respectively.
Tools you need
Before you get started, here is a list of tools you should have on hand for assembly. Most people will have these
tools in their shop:
• Metric Allen keys or a drill and Allen driver bits
• Pliers or metric wrenches
• Asmallatheadscrewdriver
• Rubber mallet (optional)

Nut Assemblies
Start by opening up all the large hardware bags and spilling all the contents out onto the table. There should
be a bag full of medium-sized, long bolts and another with medium-sized nuts, this is the M5 hardware you
need.Anotheroneofthebagswillbelledwith4rectangularplasticblocks,we’llbepreparingtheseblocksfor
installing onto the XZ-axis gantry and eventually on the Y-axis as well.
Start by pressing the M5-nylock nuts into the hexagonal cutouts. Make sure that you point the round end of the

Prepare four set of both these assemblies and set them aside for later.
Your kit will come with a set of set-screws and nuts that are used to tension and reduce backlash; however

recommend that you keep these aside and instead use some of the long M5 bolts. Feel free to install the shorter
set-screws in their place once you’ve got your machine running, if you prefer them instead.

Steel Z-axis motor mount NEMA 23 motor
(threaded)
200mm lead screw
Get the paper-wrapped Z-motor plate, the plastic Z-axis mount, and the bags full of medium-sized bolts and nuts
from the last step. You’ll also need the motor specically labeled for the Z-axis, this one is specially threaded. It
will be labeled with a sticker or come with a laser engraved
8
Start off by pushing in two M5-nylock nuts into the hexagonal holes in the 3D printed Z-axis mount. These will be
used to mount the steel Z-axis motor mount.
To the side, put the steel plate on the top of the motor, ensuring that its white connector is facing away from
the middle-sized hole on the plate. Loosely thread four M5-25mm bolts through the slots and the motor, the

Make sure to keep the round part of the nut facing towards you when pushing them in.
Screw the four M5 screws into the motor. Ensure that the connector
is facing the correct direction to make wiring easier later.

Fit the motor and plate assembly into the 3D printed Z-axis mount. If it doesn’t slide in easily, try sliding the motor

Get the bag with bearings in it and use two when pressing them into the top and bottom bore on your assembly.

Bearing on the top
Moving the motor back and forth, and tilting the plate and motor back and forth can help get this part in place.
10
Using two more of the same bolts, secure the plate and the 3D printed part together. These should thread all the
way through to the nuts that you placed earlier in the plastic mount.
Bearing on the bottom
Mount the steel plate to the 3D printed part.
