Precautions
[★★★ Make sure you read and understand the steps detailed in this guide]
! The Wexler 3D Printer is very sensitive to static electricity, so make sure you contact a
grounded object before operating the machine.
! Before repairing or making any alterations to the Wexler 3D Printer it is essential that
the machine is turned off and the power cord is unplugged.
! The Wexler 3D Printer operates at very high temperatures; allow the nozzle, the
extruded plastic and heating plate to cool before touching.
! Some plastic filaments may give off a little odor when heated, because of this the
machine should always be set up in a well-ventilated area.
! Do not wear gloves when operating or repairing, as entanglement may occur and cause
injury.
! Do not leave the machine unattended when in operation.
What's in the box?
Along with your Wexler 3D Printer, this package contains the following:
In two long boxes on the top of the package, you will find:
 Power cable,
 USB A to B cable,
 2 filament guide tubes,
 2 spool holders.
 SD card (already put inside the card reader slot behind the LCD screen)

Un-boxing
The Wexler 3D Printer was carefully packed at the factory. Please follow the unboxing steps
laid out below.
! Handle the package and its contents with extra care; do not use any unnecessary force.
! Do not remove the thin yellow film from the heating plate. It is heat resistant tape that
improves the adhesion of the extruded plastic to the plate.
! Do not remove the wrapping around the nozzle. It consists of a ceramic fiber fabric and
heat-resistant tape which helps to keep the nozzle at a constant temperature.
First, put the box on the floor in a clean and flat area. Remove the top protective foams,
there is one long box named “parts inside” and then pull out the foams packing that encloses
the Wexler 3D Printer. Inside the long box you will find a power cable, USB A to B cable, 2
filament guide tubes, and 2 spool holders.

Now take the Wexler 3D Printer out of the box. Gently lift and transfer the printer to your
work surface. You will find the extruder in the protective packaging along with the black
cable, carefully remove the protective packaging.
The build platform should now be visible. It is an aluminum plate covered in a thin
polyamide film.
This is the surface that your objects will be printed on. Remember: Do not remove the film.
You have now finished un-boxing! The next task is to set up the hardware.

Initial Hardware Installation
First is the installation of the spool holder. Install one on each side.
The installation of the spool holder is very simple – just insert it into the circular opening and
tighten the nut behind.
Then install the filament guide tube to the empty spot on the extruder, put one end of the
guide tube into the hole.
The hardware installation is almost complete.

Next, with the power switch in the 'OFF' position, confirm that the power cord is plugged into
the power outlet next to the power switch.
Now plug the USB A to B cable into the USB B-type port, do not plug the other end in yet.
Finally take the filament out of the box, install it on the spool holder and screw in the nut,
however the nut should not be over tightened.
Congratulations! You have completed the initial hardware installation! If you're ready to start
printing, proceed to the next step: Software Installation.

Special Notes to Win8 users before Software Installation “ReplicatorG”
Win 8 users please make sure that you have disabled the Driver Signature
Enforcement setting before installing the ReplicatorG software. Below is a video link
showing you how to accomplish this:

Software Installation
ReplicatorG0040 is the best software to use with the dual extruder Wexler 3D Printer. It can
be downloaded from its official website at: http://replicat.org/download
ReplicatorG0040 for Windows users can also be found in the SD card, which shipped
together with the Wexler 3D Printer.
Steps for installing your software:
1. Download the appropriate version of ReplicatorG suitable for your system from
http://replicat.org/download.
2. From the SD card shipped with your printer, browse to the “information of 3D printer”
folder and run the Python installation file and the Python acceleration components.
3. After completing the Python component installation, click Replicator-0040-Installer to
install the Replicator G software.
4. To run the Replicator G software, double click the shortcut on your desktop or in your
start menu.

Version1.0_2014.108
The following gives an introduction on how to import files (.STL) into the Replicator G
software and then generate Gcode to print your creation.
Click File > Open, then browse and select the file (.STL) that you would like to print, import
the file by double-clicking. Then the drawing will appear on the Replicator G interface.
When the object is imported you may find that it is not on the virtual build platform or even on
the screen, using the function keys indicated by the red boxes you can change the camera
angle and reposition the object onto the center of the build platform. Once you've done this,
the next step is to generate the Gcode; this is achieved by clicking on the button (Generate
GCode) at the bottom of the panel.

Explanation of GCode Settings
A new window will open up, giving you several options on how the Gcode will be generated:
A. Slicing profile: select Replicator slicing defaults for ABS printing, and select
Replicator 2 slicing defaults for PLA printing.
B. This tells the printer which extruder to use for a dual-extruder head printer, either the left
head or the right head can be selected.
C. If your sample will have any hanging surfaces, it is recommended to have support. None
means no support. Exterior means surface support. Full support means all support.
D. Object infill: where 100% is a solid print, 0% is a hollow object. The recommended
setting is 10%, this will save time and filament. Low infill also can reduce the corners lift up
issue during ABS printing.
E. Layer Height: this controls the vertical resolution of the print. The recommended
thickness is 0.20mm.
F. Number of shells: this is the wall thickness; it’s usually set at 1.
G. Feedrate: is the speed at which the filament is fed into the extruder. This usually set
between 30 and 70. For ABS printing, 60 is recommended, for PLA printing, 100 is
recommended.
H. Travel feedrate: is the speed at which the printer head moves over the base, it’s usually
set between 30 and 100. For ABS printing, 80 is recommended, for PLA printing, 120 is
recommended.
I. Print Temperature: is the temperature to which the nozzle is heated. This varies between
filament types. For ABS, set it to 220. For PLA, set it to 200.
