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!

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 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.
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.

PRIMARY COLOUR
Example z_joint_lower_x4.stl
These les will have nothing at
the start of the lename.
ACCENT COLOUR
Example [a]_tensioner_left.stl
We have added “[a]” to the front
of any STL le that is intended to
be printed with accent color. The
parts are marked with a heart in
the manual.
QUANTITY REQUIRED
Example [a]_z_belt_clip_lower_x4.stl
If any le ends with “_x#”, that is telling
you the quantity of that part required to
build the machine.
FILE NAMING
By this time you should have already downloaded our STL les from the Voron GitHub. You might have noticed that we have
used a unique naming convention for the les. This is how to use them.
INTRODUCTION
CLEAR/TRANSPARENT
Example [c]_led_diffuser.stl
We have added “[c]” to the front
of any STL le that is intended
to be printed with clear or
transparent lament (cloudy is
better than clear; white or light
grey may also work in a pinch).
OPAQUE
Example [o]_led_diffuser_mask.stl
We have added “[o]” to the front
of any STL le that is intended
to be printed with an opaque
lament (blocks light, dark
colours and blacks).

REPORTING ISSUES
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-Stealthburner/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.
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 clarication on. It can 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
HARDWARE REFERENCE
SELF TAPPING SCREW
Fastener with a pronounced thread
prole that is screwed directly into
plastic.
FLAT HEAD COUNTERSUNK SCREW (FHCS)
Metric fastener with a cone shaped head and
a at top.
ISO 10642
HEAT SET INSERT
Heat inserts with a soldering tip so that
they melt the plastic when installed.
As the plastic cools, it solidies around
the knurls and ridges on the insert for
excellent resistance to both torque and
pull-out.
WASHER
Usually stamped from sheet metal this
type of spacer is not as consistent in
thickness as the shims are. Only used in
M3 size.
DIN 125
SET SCREW
Small headless screw with an internal
drive. Used in pulleys and other gears.
Also called a grub screw.
ISO 4026
HEX NUT
Hex nuts couple with bolts to create a
tight, secure joint.
ISO 4032

HEAT SET INSERTS
This design relies heavily on heat
set inserts. Make sure you have the
proper inserts (check the hardware
reference for a close-up picture and
the Sourcing Guide for dimensions).
If you’ve never worked with heat set
inserts before we recommend you
watch the linked guide.

BELOW SURFACE
The bottom heatset insert needs to sit
below the surface of the printed part.
Mind the cutout in the part and make sure
to install it straight.
HEAT SET INSERTS
BELOW SURFACE
The top heatset insert needs
to sit below the surface of
the printed part.

OPTION: TOOLHEAD PCB
If you opt to use a toolhead PCB, add additional heat set inserts into locations highlighted below.

HEAT SET INSERT
Be careful when inserting this heat set
insert. It’s easy to accidentally touch the left
side of the part with the soldering iron.

GENERIC CABLE CHAINS
The 3-hole pattern is usually
found on generic cable chains.
IGUS CABLE CHAINS
IGUS chains have 2 mounting
holes.

PRINTER SPECIFIC MOUNTS
V2, Trident and Legacy use the
same printed parts. Extra parts
are included for SwitchWire.

FLUSH WITH SURFACE
The heatset insert needs to sit ush or
slightly below the surface of the printed
part.
ACCENT PART?
Look for Voron heart next to the part.
It indicates that this is a part that is
usually printed in the accent color.

M3x16 SHCS
TOLERANCES, EXTRUSION MULTIPLIERS AND YOU
The part has tight tolerances. If it doesn’t t together well the
printed parts are likely over-extruded.

A NOTE ON SPRINGS
Longer/shorter/stiffer springs will change the tension characteristics and
have an impact on how well the tension mechanism works. Consider
buying the original Bondtech part as those are known to work well. If
sourced from a different vendor check if it’s roughly 12mm long with an
outer diameter of 6mm and a wire thickness of 1mm.

MR85 Bearing
MOTOR PLATE
BEARING FIT
Fully seat the bearing into the plastic pocket.
Apply even pressure to insert them. Avoid
pressing on the inner ring of the bearing.
If the t is too tight the printed parts are
likely over-extruded.
MR85 Bearing
CHECK BEARING FIT
The bearings must slip on and off the shaft
easily to allow the gear to self-centre.
Pressing the bearings on the shaft will
damage them.
Lightly sand the shaft if required.
