Chapter 1 Intro
Step 1.1 What is included in this kit?
In this kit you will find all the necessary parts for converting your regular Voron 2.4 3d printer
into a sequential Conveyor 3d printer. Parts lists are indicated on each step for better
understanding and guidance.
Step 1.2 Needed tools
In order to fully install this kit, you will need the next tools:
Set of Allen keys
Adjustable wrench or wrench kit
Measuring tape
Vernier caliper
Metal ruler (for alignment)
Chapter 2 Disassembling Voron 2.4 front doors and heatbed
In order to get ready to install this kit, you have to disassembly various segments of the original
3d printer, this part will guide you through entire process of preparation and getting ready to
install new parts.
*Please be aware some original parts will be discarded and won’t be installed.

Step 2.1 Removing front door parts
Remove all brackets, panels and hinges from both front doors.
Figure 2 remove highlighted parts
Step 2.2 Removing Heatbed
Before starting to remove the heatbed, we need to secure both DIN rails that holds all
the electronic components, so we flip the printer carefully and remove the bottom
panel.
After that, we use the printed BRACKET_DIN_RAIL_X4.STL part and secure the DIN rails
using 4 units M4x8 screws and 2 units T-nuts on each bracket as shown in the next
picture.
Figure 3 Securing DIN rails before removing heatbed bars

We remove heating bed at this point, by releasing 4 units M3 bolts that holds it down,
it is highly recommended to remove any magnetic base plate, and clean the aluminum
heatbed with IPA in order to remove any glue from it:
*Note: Do not disconnect the heatbed from the electronics, just keep it loose for next
steps.
Figure 4 Removing heatbed screws
Now we can securely remove both 2020 aluminum bars that holds the heatbed, by
removing the 4 screws on each side, you have to disconnect cable from the Z endstop
unit, since it won’t be used:

Chapter 3 Preparing frame
We are pretty much ready to install our kit.
Step 3.1 Installing bottom plates
Let’s identify each bracket part first:

Insert both sides M6 Knobs supplied in the kit:
Figure 22 Inserting M6 Knobs on both sides
Belt tensioning:
One way to check for the right belt tension and alignment is to roll the belt by hand and it
have to move easy, smooth and straight without wobbling or needing to apply too much
force.

Belt motor installation: On the LEFT FRONT side of machine, take the Timing Pulley 60T,
bore 12mm GT2 and insert it on the end of the REAR ROLLER, then using the original Y
motor and pulley (using M4x8mm Screws and M4 slot nuts), proceed to install it. At this
point place the GT2 Timing Belt Closed Loop and align both pulleys, then adjust the
motor bracket in order to tension the closed loop belt. As shown in the next picture:

Installing heatbed Assembly: Install heat bed element back again.
Proceed to insert Heated bed with support alu bars assembled, from the left side of
machine right under the tensioned BELT. (cable of heatbed will come out from the left
side to the machine and going to the electronic compartment)

Chapter 5 Finishing installation
Step 5.1 Belt holders mounting
Belt holders on each side of the Conveyor belt will help to reduce possible warping and
better stability for the belt once printing over it, in order to install them follow the
next scheme and repeat on the opposite side, after that slightly adjust the screws, in
order to get even and slightly pressure over the belt, belt holder should overlap the
belt for about 10 mm or less on each side:

2 M5 WASHER +
1 SPRING
1 M5 T-NUT

Step 5.2 Face plate mounting
Install provided face plate into the front of the machine, using 2 units M5x8 screws
and M5 T-nuts, place it centered on the printer:
Figure 30 Install face plate, keeping a gap of 2mm from the belt
Step 5.3 Installing front STRIP CURTAIN
Strip curtain is required to keep heat inside the chamber, and also for letting parts to
come out easily from the belt.
Use supplied top bracket in order to fix all the strips to the top frame, using M4x8
screws and M4 T-nuts, you can use a piece of blue tape to pre-arrange them first over
a table for easy mounting, overlap is about 12mm for each strip:
