residential installation. This equipment generates uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is noguarantee that interference will
not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following
measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment to an outlet on a circuit different from that to which the receiver
is connected.
•Consult the dealer or an experienced radio/TV technician for help.

1. About Geeetech 3D WiFi Module
1.1 Introduction
Geeetech developed 3D WiFi Module, with the only aim of enabling all the 3D printing
hobbyists to control their printer wirelessly. 3D WiFi Module is mainly composed of two
parts: control board and Wi-Fi module. Thumb-size as it is, it is powerful enough to connect
your 3D printer with Geeetech’s cloud server, making it a reality for you to control your
device on EasyPrint 3D App.
3D WiFi Module is ready to use right out of box. You just need to connect your printer
to its USB port and finish simple configurations on EasyPrint 3D App. That’s all. Then you
can start to control your printer wirelessly.
3D WiFi Module is cloud-based.Via EasyPrint 3D App, it is extremely simple and
convenient to direct control over your printer anywhere and anytime. Besides, you would
have access to a large cloud gallery, which covers 9 categories of 3D models for printing.
What’s more exciting is that you could record and share your printing moments on EasyPrint
3D App in seconds.
3D WiFi Module is broadly compatible with many different kinds of 3D printers on the
market. As long as the USB to serial chip of your printer belongs to one of these three ones
(CH340, FT232 and PL2303) and is controlled by G.code instructions, our 3D WiFi Module
can upgrade your machine as Wi-Fi enabled and make it comparable to other prohibitively
expensive Wi-Fi connected 3D printers.
Coded professionally and adopting high-performance chips, 3D WiFi Module could
transmit model files and your commands to your printer in a stable and reliable way.

1.2 Main Features of 3D WiFi Module
As a bridge for data transmission between mobile phone and 3D printer, 3D WiFi
module integrates some instructions, convenient for users directing control over 3D printer
from App. Besides, it is compatible with the feedback info from 3D printer to control the
printer and display the related printing data on App.
In this section, a brief introduction to its main features is made to help get a better
knowledge of how 3D WiFi module works.
a. Config mode: Long press the hole labeled with “set”with a pin about 3s, until the
Wi-Fi indicator light turns dim and flickers quickly. Loosen the pin and 3D Wi-Fi will enter
the config mode. In the config mode, you can finish the Wi-Fi connectivity onApp.
b. When the Wi-Fi indicator light flickers quickly and you do not loosen the pin, the
light will flicker slowly to enter the reset mode. In the reset mode, your phone could not
detect GT_printer hotspot.
c. When the network is not stable, 3D WiFi module will re-connect the hotspot
automatically.

In the following part, a detailed introduction to the App menu will be made.
1.3 Tips for Using 3D WiFi Module
* Make sure 3D WiFi module and 3D printer could communicate smoothly with your
USB cable. If not, please contact with [email protected], we will help you pair the basic
firmware with your USB interface.
* Ensure that M26, M27, M110, M114, M119 commands are valid and of correct format,
so that EasyPrint 3D App could display the printing status normally and operations via App,
such as stopping printing and leveling the building platform, are available.
M26, M27, M110 is related to the display and modification of printing status and
parameters on App, when the printer runs with SD card or TF card. M114 and M119 for
leveling the building platform.
If the format of these commands is not in alignment with what is shown in the following
table, please make the corresponding modification.
*You can use serial debugging tools or Repetier-host to send these commands to your
3D printer to test how your machine responds.
M26
Start printing from a specific byte of a g.code file, which is being printed.
G.code: M26 Snnn. ―nnn‖for the numbers.
M27
Obtain info of printing progress.
G.code: M27; Return: ―SD printing byte nnn/nnn‖
M110
Set the line sequence, for instance, the present line No. is nnn, and the next
line should be nnn+1.
G.code: Nnnn M110
M114
The present coordinates for X/Y/Z/E.
G.code: M114; Return: ―X: nnn Y: nnn Z:nnn E: nnn‖
M119
G.code: M119
Return: eg. ―x_min: H y_min:H z_min:L‖
Or ―x_min:OPEN x_max:TRIGGERED y_min: OPEN y_max: TRIGGERED
z_min:TRIGGERED z_max: OPEN‖

2. Install EasyPrint 3D App
Download the EasyPrint 3D APP and install it by following the instructions.
http://www.geeetech.com/firmware/EasyPrint_3D_Android.apk
You could also download EasyPrint 3D App on Google Play and App Store.
Once finishing installation, enter Me to register and log in.
Note: As the EasyPrint 3D APP is continuously upgraded, some UI and workflow may
be different, please follow the APP.
Here are the login steps.

4. Wi-Fi Configurations
Detailed configuration procedures are as follows.
Step 1. Use the power cable to connect 3D WiFi Module with your adapter to power it
up. The red power supply indicator light is on, while the yellow indicator lights for USB and
Wi-Fi signal flicker quickly.
Step 2. Connect your 3D printer to the USB port of 3D WiFi Module with your USB
cable for data transmission. The red power supply indicator light and the yellow USB
indicator light are on, while the yellow Wi-Fi signal indicator light flickers slowly.
Step 3. Please check if the TF card is inserted into the slot in the right way.

Till here, the configuration between App and your printer is finished. Now you can print
and control the printing via EasyPrint 3D App.
Note: 1. During the above config process, your Phone is connected to the GT-printer
wifi hotspot, which has no access to the internet connection. So you will be logged out. After
your successful config., your phone will be connected to your previous network automatically.
If not, please connect it manually and log in to EasyPrint 3D again.
2. If you are asked to switch the network during the wifi config, please choose NO to
stay with the GT-printer wi-Fi network, as shown in the following picture.
5. Printing via EasyPrint 3D App
As above, once the configuration between APP and the printer is successful, you can
start to print.
Note: ATF card is still needed when print via Wi-Fi to save the files.
