Basic Function

Zubi is a mounting kit electronic that allows to the most of 3D printers to be networked by simply connecting the USB cable to the  Zubi instead of to a PC.

Once that Zubi is connected to the 3D printer it will be identified by IP address\Port who set Zubi and will can communicate with the most common programs for 3D printers or natively or through utilty of convenience such as specific programs of virtual com.

First start-up

Zubi is preloaded with the configuration of 115200 baud.

In the case in which you need to use the configuration of 250000 baud will suffice to perform the firmware update as indicated here.

On the first start-up Zubi is configured as AP (Access Point) which means it has its own WIFI network to which you should be logged in the same manner in which you access to any WIFI network from a PC or mobile phone.

Following are the references:

Network name WIFI : HI-LINK_XXXX where  XXXX are variables values that change from module to module

Password : 12345678

Once accessed the network HI-LINK_XXXX just connect to port 8080 to pilot the 3D printer.

In summary Zubi waits for a TCP / IP address / port, which by default is configured as described above ( Port 8080) by turning any data arrivals from 3D printer and back to that connection.



Zubi allows for different configurations to suit the various needs.

Here we report the fundamentals that are:

Although in this section will describe only these few basic configurations please note that Zubi being also a real router has the possibility of a variety of configurations ranging from the internal configuration of a firewall to the operation mode, but we leave the initiative to the individual for deepening of the same.

Currently in order to change any configuration (except firmware update) you must be accessed via a browser at :

User name : admin

Password : admin

So, will be presented with the following screen:


where highlighted in red and numbered are indicated some  parameters that describe below:

1) SSID : name of the network with which it presents ZUBI 
2) Password : passwords to access the Zubi network WIFI
3) baud rate : baud rate to be configured depending on the firmware loaded on Zubi

By clicking on the top left pane highlighted in red, labeled with click you switch to a new advanced setup screen which will describe some features later.


Change baud rate

If you wish to change the baud rate from 115200 to 250000, or vice versa, you must change the entry field indicated with the number 3 and click on the apply button.

Be careful to change only the first part of the field 3 preserving the items that are to follow ,8,n,1


Remember to also update Zubi with the correct firmware to 115 or 250 as shown here. 

Change WIFI mode 

As anticipated Zubi default is in AP mode which means that in order to communicate with the same one must first access to its network WIFI HI-LINK_XXXX,

this mode can sometimes be uncomfortable, in these cases you can configure Zubi for you to connect also to your WIFI network (such as the home or office wifi) and then behaves like a normal shared network printer in your chosen network.

To do this configuration you will always have to go to

User name : admin

Password : admin

and click on the top left pane highlighted in red labeled with click (where there is the inscription Hi-link),

click Operation Mode and select AP client as shown in the following image:


click Apply.

At this point, click to open the left menu where indicated Wireless Settings

and click AP Client.

The following screen appears:




1) SSID : name of the network to which you want to connect.
2) MAC Adrress: mac address of the network to which you want to connect (optional)
3) Security Mode : type of security to use to connect to the network.
4) Encryption Type: Encryption type of network to which you want to connect
5) Pass Phrase : "Password" of the network to which you want a connection.

by typing the correct data in the 5 fields indicated for the network of your choice and then click apply, Zubi will access  also to the network of your choose.

In the table "Site Survey" displays below the five fields described above are displays the wireless networks visible from Zubi with all the details needed to be included in the 5 fields.


If you were to see any wireless network listed, try running one SCAN clicking SCAN.

Done this, wait until zubi enters in your network, open the menu and click on Administration status.

In the field 1 will be shown the IP to be used to contact Zubi also from your network.




Currently Zubi comes with the firmware configured with the baud rate to 115200.

If you need to configure Zubi to 250000 baud to allow proper communication with 3D printers configured to 250000 baud proceed as follows:

  • Download the desired firmware  (115 o 250)from the Download Area(must be registered
  • Rename the downloaded file in ZUBI.hex and load it on a USB stick.
  • Insert the key into the USB port of Zubi.
  • Start or restart Zubi.
  • Wait about 10 seconds.
  • At this point Zubi is updated with the Firmware version chosen.



Once connected Zubi to the 3D printer, the same will be used in the same way in which you used it when it connected with a cable directly to a PC with the difference that there is no need to use a USB cable, and so, you can potentially  control the printer from anywhere in the world, always with the appropriate configurations.

There are some programs like Repetier-Host downloadable at the following link that have the ability to connect directly to an IP address\port, in this case there are no further expedients to be used,

There are instead, programs that do not allow you to connect directly to a network address such as Pronterface downloadable at the following link, in this case you can use virtual com programs that allow you to map an IP address/port to a serial\Com Port so you can use Zubi as a printer physically connected (wired) to your PC. 

One of the programs you can use as Virtual com is NetBurmer Virtual com downloadable at this link .

After installing NNDKVComm.exe,run VirtualSErialPorts.exe from where you installed it, the following screen appears:




 select New and the following screen appears:


Insert in the field :

Device IpThe IP address of Zubi (the one in the example set by default)

Device Portthe door of Zubi (in the default port of Zubi)

and select OK.

At this point you have configured Zubi so that will be visible from any programs on the Port in this case COM10.





It 'also available  an Android app with which you can control the 3D printer directly from the mobile downloadable at the following link:
