INTRODUCTION
Before you begin on your journey, a word of caution.
In the comfort of your own home you are about to assemble a robot. This
machine can maim, burn, and electrocute you if you are not careful. Please
do not become the rst VORON fatality. There is no special Reddit air 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!
THE VORON TEAM

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 les off our Github repository if there are
sections you need clarication on. It can be sometimes be easier to follow along when you have the
whole assembly in front of you.

BUTTON HEAD CAP SCREW (BHCS)
Metric fastener with a domed shape
head and hex drive. Most commonly
found in locations where M5 fasteners
are used.
ISO 738 0 -1
SOCKET HEAD CAP SCREW (SHCS)
Metric fastener with a cylindrical head
and hex drive. The most common
fastener used on the Voron.
ISO 4762
HEX NUT
Hex nuts couple with bolts to create a
tight, secure joint. You’ll see these used in
both M3 and M5 variants throughout this
guide.
ISO 4032
SHIM
Not to be confused with stamped
washers. These are used in all M5 call-out
locations in this manual.
DIN 988
IDLER
GT2 idler used in the motion system of
the Voron.
PULLEY
GT2 pulley used on the motion system
of the Voron.
HARDWARE
POST INSTALL T-SLOT NUT
Nut that can be inserted into the slot of
an aluminium prole. Used in
both M3 and M5 variants throughout this
guide.
HAMMER HEAD NUT
Nut that can be inserted into the slot of
an aluminium prole. Used
exclusively for panel mounting, all other
components use T-Slot nuts.

HARDWARE
HEAT SET INSERT
Heat inserts with a soldering tip so that
they melt the plastic when installed.
As the plastic cools, it solidies around
the knurls and ridges on the insert for
excellent resistance to both torque and
pull-out.
F695 BEARING
A ball bearing with a ange used in
various gantry locations.
LM8LUU BEARING
A long linear ball bearing used in the Z
axis.
THUMB NUT
Used in the print bed both for manual
tramming and as a spacer.
DIN 466-B
SELF TAPPING SCREW
Fastener with a pronounced thread
prole that is screwed directly into
plastic.

GETTING EXTRUSIONS TOGETHER
Separate the extrusions you’re going
to need for this section of the build.
We’ve laid out all the parts you should
have and highlighted the ones that will
be used in the following sections.
EXTRUSIONS

10
WWW.VORONDESIGN.COM
PREPARE 10 EXTRUSIONS
All 10 extrusions are going to be used in this
section. Prepare them as shown to the left.
M5x16 BHCS
EXTRUSIONS

WWW.VORONDESIGN.COM
BUILD ON A FLAT SURFACE
Build the frame on a glass or granite surface
to ensure you can get it as square as possible.
UPSIDE DOWN ASSEMBLY
For ease of assembly we recommend to
assemble the frame upside down.
Mind the position and orientation of the access
hole on the vertical extrusions.
FIRST BLIND JOINT

REMAINING UPRIGHTS
MIND ACCESS HOLE POSITION
We do our best to call out things that may bite
you later in the assembly process but may skip
things that seem obvious to us. If in doubt
please refer to the CAD model, it might save
you some considerable time down the road.

ADJUST TO 90MM DISTANCE
The extrusions that will later hold the Y-Rails are
spaced 90mm from the top extrusions (110mm
from the work surface).
Make sure that they sit ush with the vertical
extrusions and aren’t twisted/rotated. A small
machinist square will help with this task.
Y EXTRUSIONS

14
WWW.VORONDESIGN.COM
BOTTOM EXTRUSIONS
FINDING THE RIGHT POSITION
The bottom extrusions are spaced 320mm from
the Y extrusions.
Use the linear rods of the Z drive as a guide. Make
sure that you are able to slide them in from the
side.
Make sure that the extrusions sit at an 90° angle
and are free of any rotation/twist. The outsides of
the extrusions should be ush.
The position of the front/back facing extrusion is
not critical.

FLIP RIGHT-SIDE UP
This concludes the rst section
of the assembly. Time to put the
printer on it’s own feet.
Don’t forget to take a photo of
your success.

A/B DRIVE

WWW.VORONDESIGN.COM
A/B DRIVE MOTORS
The picture shows the A
Drive motor (left hand side of
the printer). B Drive motor is
assembled in the same fashion
with the pulley orientation
ipped.
GRUB SCREWS
aka the root of all issues
Use thread locker on all grub
screws.
Loose grub screws account for
the majority of issues that our
users report. Save yourself hours
of troubleshooting and apply
thread locker to all grub screws
during the build.
See the products application
notes for instructions.
