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

INTRODUCTION
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)
MATERIAL
ABS
LAYER HEIGHT
Recommended: 0.2mm
EXTRUSION WIDTH
Recommended: Forced 0.4mm
INFILL TYPE
Grid, Gyroid, Honeycomb, Triangle or Cubic
INFILL PERCENTAGE
Recommended: 40%
WALL COUNT
Recommended: 4
SOLID TOP/BOTTOM LAYERS
Recommended: 5
PRINT IT FORWARD (PIF)
Often times our community members 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.
Check Discord if you have any interest in having someone help you out.

HOW TO GET HELP
If you need assistance with your build, we’re here to help. Head on over to our Discord group and post
your questions. This is our primary medium to help VORON Users and we have a great community that
can help you out if you get stuck.

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 7380-1
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
FLAT HEAD COUNTERSUNK SCREW (FHCS)
Metric fastener with a cone shaped head and
a at top.
ISO 10642
PULLEY
GT2 pulley used on the motion system
of the Voron.
HARDWARE

WWW.VORONDESIGN.COM
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.
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.
SELF TAPPING SCREW
Fastener with a pronounced thread
prole that is screwed directly into
plastic.

INTRODUCTION
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.

BALL-END DRIVER
Some parts of this design require the use of a
ball-end hex driver for assembly. We recommend
you get a 2.5mm and 3mm one.
INTRODUCTION
2.5MM HEX DRIVER
The 2.5mm hex driver will see a lot of use in this
build. A quality driver is strongly recommended.
Refer to the sourcing guide for suggestions.

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.

FRAME
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 often recommend to
assemble components upside down.
Assemble on a at surface to ensure that the
base is square.
BLIND JOINT ACCESS HOLES
Use the access holes to fasten the bolts.
https://voron.link/onjwmcd
FIRST BLIND JOINT
This design relies on blind joints to
assemble the frame. We outlined the
basics of blind joints on page 8.
If you’ve never assembled one before
we recommend you watch the linked
guide.

T-NUTS?
We don’t show the insertion of T-Nuts in our
assembly manuals.
The T-Nuts we recommend can be inserted at
any point during the installation.

FRAME
VERIFY DIMENSIONS
Make sure the frame is square and that all
positions are set correctly before moving on.
Check the 90° angles with a machinist square.
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.

BUILD ON A FLAT SURFACE
Build this section of the frame on a glass or
granite surface to ensure you can get it as
square as possible.
TILT FRAME 90°
The access holes for the Blind Joints are at the
bottom. Lay the frame at on it’s side to access
them. This also helps in mounting the uprights
ush to the base.

17
WWW.VORONDESIGN.COM
VERIFY DIMENSIONS
Check the corners and make sure that they are at 90° angles. Use a small machinist square.
If you have the measuring equipment verify that both uprights are dead on parallel.
Correct the angle is required. Failure in doing so may result in a sticky Z Axis.

MGN12 Linear Rail
Z RAILS
CENTERED RAIL INSTALLATION GUIDE
Use the guides to position the rail in the center
of the extrusion prior to fastening the bolts.
NO STOPPER ON LEFT RAIL
The left rail does not have a stopper in place
to prevent the carriage from sliding off the rail.
Some rails come with little plastic stop pins,
you can leave the bottom one in place.
If your rail does not have these stop pins leave
the last bolt slightly loose to act as a stopper.
Tip: Mark the location with some tape to draw
your attention to it later.
MIND THE CARRIAGE
The carriages are designed to slide along the rail easily.
This unfortunately also includes sliding off the rails.
Dropping the carriage likely irreparably damages it.
