Before you begin on your journey, a word of caution.
This machine can maim, burn, and electrocute you if you are not careful.
Please do not become the first VORON fatality.
There is no special Reddit flair for that.
Please, read the entire manual before you start assembly.
As you begin wrenching, please check our Discord channels for
any tips and questions that may halt your progress.
Most of all, good luck!

PART PRINTING GUIDELINES
The Voron Team has provided the following print guidelines for you to follow in order to have the best chance at
success with your parts. There are often questions about substituting materials or changing printing standards,
but we recommend you follow these.
3D PRINTING PROCESS
Fused Deposition Modeling (FDM)
INFILL TYPE
Grid, Gyroid, Honeycomb, Triangle or Cubic
MATERIAL
ABS/ASA
INFILL PERCENTAGE
Recommended: 40%
LAYER HEIGHT
Recommended: 0.2mm
WALL COUNT
Recommended: 4
EXTRUSION WIDTH
Recommended: Forced 0.4mm
SOLID TOP/BOTTOM LAYERS
Recommended: 5
PRINT IT FORWARD (PIF)
Often times community members that have issues printing ABS will bootstrap themselves into a VORON using
our Print It Forward program. This is a service where approved members with VORON printers can make you
a functional set of parts to get your own machine up and running. Further Details about the PIF program can be
found on the Discord server or by visiting https://pif.voron.dev.

FILE NAMING
By this time you should have already downloaded our STL files from the Voron GitHub.
You might have noticed that we have used a unique naming convention for the files.
This is how to use them.
PRIMARY COLOR
B_Drive_Frame_Lower_x1.stl
These files will have nothing at the
start of the filename.
ACCENT COLOR
[a]_Tensioner_Knob_x2.stl
We have added “[a]” to the front of any
STL file that is intended to be printed
with accent color. The parts are marked
with a heart in the manual when they
first appear.
QUANTITY REQUIRED
[a]_Thumb_Nut_x3.stl
Any file that ends with “_x#” is
telling you the quantity of that part
required to build the machine.
CLEAR / TRANSLUCENT
[c]_Display_Diffuser_x1.stl
Any file that begins with [c] is
intended to be printed in a clear or
translucent color that allows light
to penetrate through it.
STL FILE LIST
We have put together a comprehensive list of all the STL
files used in this manual you can use this to keep track of
parts you have printed, identify the names of printed parts,
and/or reference where they are used in the body of this
manual. Simply copy the document from the link and you can
markup a local copy for yourself: https://voron.link/3p5kekz.

THIS IS JUST A REFERENCE
This manual is designed to be a simple reference manual. Building a Voron can be a complex endeavour and for
that reason we recommend downloading the CAD files off our Github repository if there are sections you need
clarification on. It can sometimes be easier to follow along when you have the whole assembly in front of you.
DOCS https://docs.vorondesign.com/

REPORTING AN ISSUE
Should you find an issue in the documentation or have a suggestion for an improvement please consider opening an
issue on GitHub (https://github.com/VoronDesign/Voron-0/issues). When raising an issue please include the relevant
page numbers and a short description; annotated screenshots are also very welcome. We periodically update the
manual based on the feedback we get.

HARDWARE - REFERENCES

BUTTON HEAD CAP SCREW (BHCS)
Metric fastener with a domed shaped
head and hex drive. Most commonly
found in locations where M3 fasteners
are used.
ISO 7380-1
FLAT HEAD CAP SCREW (FHCS)
Metric fastener with a cone shaped
head and a flat top.
ISO 10642
SOCKET HEAD CAP SCREW (SHCS)
Metric fastener with a cylindrical head
and hex drive. The most common
fastener used on the Voron.
ISO 4762 / DIN 912
PULLEY
GT2 pulley used on the motion system
of the Voron.
HEX NUT
Hex nuts couple with bolts to create a
tight, secure joint. You’ll see these used
in both M2 and M3 variants throughout
this guide.
ISO 4032 / DIN 934
HEAT SET INSERT
Heat the inserts with a soldering iron
so that they melt the plastic when
installed. As the plastic cools, it
solidifies around the knurls and ridges
on the insert for excellent resistance to
both torque and pull-out.

F623 BEARING
A ball bearing with a flange used in
various gantry locations.
MAKERBEAM T-NUT
This is a special, longer, T-nut
that is only used in the toolhead
for securing the belts.
M3 SHIMS
Not to be confused with stamped washers.
These are used in all M3 call-out locations
in this manual.
3x6x0.5 DIN 988
ATTENTION BUBBLE
This logo denotes steps that are
common areas that mistakes
can occur.
SELF TAPPING SCREW
Fastener with a pronounced thread profile
that is screwed directly into plastic.
VORON HEART
Look for Voron heart next to
the part. It indicates that this is a
part that is usually printed in the
accent color.
KIT CARD
Kit providers often include part options that are not
standard design spec. We’ve added notes for popular
ones marked with this icon.

HARDWARE - BLIND JOINTS
10
BLIND JOINT BASICS
Blind Joints provide a cost-effective and rigid
assembly method.
The head of the BHCS is slid into the channel of another
extrusion and securely fastened through
a small access hole in the extrusion.
If you’ve never assembled one before we
recommend you watch the linked guide.

HARDWARE - TOOLS

BALL-END DRIVER
Some parts of this design require the use of a
ball-end hex driver for assembly. We recommend
you get 1.5mm, 2mm and 2.5mm sizes.
2mm HEX DRIVER
The 2mm hex driver will see a lot of use in this
build. A quality driver is strongly recommended.
Refer to the sourcing guide for suggestions.
ADDITIONAL TOOLS
We provide additional tool recommendations in our
sourcing guide. Visit https://vorondesign.com/sourcing_guide
and switch to the “Voron Tools” tab at the bottom of the page.

EXTRUSION PREP - DRILL GUIDE

PREPARE EXTRUSIONS
The V0 frame uses blind joints. A drilling guide is provided
to locate the holes. If your frame is already pre-drilled you
can ignore this step. The through-hole should be large
enough to allow access for a 2mm hex drive (3mm or 7/64”).
The following pages show the minimum required
preparation for the extrusions.

EXTRUSION CALL-OUTS
To avoid confusion we will call out the
extrusions by the names shown on
these reference pages.
To help assembly along you may want to
label the extrusions or print the reference
page for a faster lookup.
ALL UNITS ARE METRIC
If a unit is not specified assume it’s metric.
I’M MISSING EXTRUSIONS!?
If you purchased a kit you may not have
un-drilled “F” extrusions or un-tapped
“A” extrusions. This is ok; these pages
denote the minimum requirements for
the extrusions.

POPULATING NUT CARRIERS
Depending on how much M2 hardware you sourced, you may
not be able to fully populate the M2 Nut Adapters.
To fully populate all 5 adapters you need 50 M2x6 screws
and M2 nuts.
M2 Hex Nut
NUT BARS
Many kits come with metal bars with
tapped M2 holes that replace these
printed components.

FRAME - Y RAILS
19
LINEAR RAILS - PREPARATION AND MOUNTING
Most linear rails arrive with shipping oil. To ensure
a smooth gliding motion and long service life, this oil
needs to be removed and its rail carriage greased.
See the Voron sourcing guide for a recommended list
of lubricants. We attached a link to a video guide to
get you started. All 5 linear rails require the same
lubrication prep.
https://voron.link/agu0nes
MIND THE CARRIAGES
The carriages are designed to slide along the rail easily.
This unfortunately also includes sliding off the rails.
Dropping the carriage will likely result in irreparable
damage. Keep each carriage with its respective rail.
They are not meant to be swapped.
In a pinch, you can secure the
carriage to the rail by running a
cable tie in the rail’s screw holes.

MIND THE ACCESS HOLE LOCATION
We do our best to call out things that may bite you later in the
assembly process. If in doubt please refer to the CAD model,
it might save you some considerable time down the road.

E Extrusions
NUTS DOWN, NUTS UP?
Sliding the nut bars in face up or face down? Both options will
work, some extrusion profiles (like LDO) work better with them
face up as the nuts are less likely to pop out of their printed
pockets when installing the screws. But both orientations
work just fine.
