Louet Dobby 2.0 Web Interface- Software Version 2.2
General Information
The unique Louët dobby 2.0 allows you to use the electronic Dobby without
commercial weaving software.
The Dobby 2.0 contains a computer that includes the software for the web interface
and also storage space for weaving patterns. In order to use this software, you do not
need to install any software on the computer. This software allows you to use a web
browser (such as Internet Explorer, Safari, Firefox or Google Chrome) to easily
display the Dobby software via a wireless connection (WiFi).
This guide contains a variety of technical terms you may be encountering for the first
time. We’ve included a Dobby Dictionary in the back of this guide that explains the
terms used.
Difference between Dobby Web Interface and Commercial Weaving Software
The main function of the built-in Dobby web interface software is to control the Dobby
during weaving, which is to indicate which shaft combination should be selected for
each pick of the weaving pattern. These instructions are indicated by the English
term 'lift plan'.
The web interface software allows you to enter and modify a lift plan, but you can
also import a lift plan that you have created using weaving software.
One of the great advantages of the web interface software is that it is independent of
the computer or operating system. If new software versions are available from the
Louët Dobby, you can update them directly via the Internet or through the USB stick
update feature. The first version of the Dobby web Interface Software (2018) was still
quite primitive. This major update in 2020 to version 2.2 has many new and improved
features. In the future, the functions may be expanded further or improved.

Weaving software also shows the threading
and weave
Independent commercial weaving design software programs (Fiberworks PCW,
ProWeave, PixeLoom, Weavemaker, WeaveIt, Winweaving, etc.) allow you to design
a weaving pattern by combining threading, and treadling sequences. With an
additional driver (available for purchase separately) you can also use the
independent software program to drive the Louët Dobby. For this, you will need the

3
USB cable that connects the Dobby to the computer. When the Dobby is connected
to the computer via USB cable connection, the web interface software is temporarily
deactivated. Once you unplug the USB cable from the Dobby, you can use the web
interface software again.
The instructions for creating the connection can be found in the Dobby 2.0
Installation Guide and in the manual of the independent weaving software program.
Although you do not need commercial weaving software to control the Dobby, this
software is certainly useful for creating patterns. The advantage of the Dobby 2.0
web interface software is that you do not have to put your computer on or next to the
loom and you can use the wireless (WiFi) connection.
Register your Dobby 2.0 at louetdobby.nl or louetdobby.com
After registering your dobby on louetdobby.nl or
louetdobby.com you will get access to the Dobby 2.0
user page. Here you can find tips, free Dobby patterns,
information about software updates and ask questions.
When registering, you will need the serial number of the
Dobby. This is on the label under the solenoid. NOTE:
Write down your serial number as you will need it in any
software upgrade process and its not visible when the
dobby is mounted on the loom.

Starting Dobby Web Interface (all sessions after the first session)
1. Turn on the dobby computer: Switch to 1 (=ON)
If you use the Louët WiFi connection without an Internet connection (IP address
10.42.0.1 on the dobby display):
1. Use the network settings for your device’s WiFi to connect to Louëtwifi (See
the instructions for the 'first session').
2. You can set the network settings on your device to automatically restore the
connection if both devices are turned on.
If you have set up the connection to the Internet (IP address 192. xx. xx. xx or 172.
xx. xx. xx), the Dobby will automatically contact the network. If the network is not
available, the text "No Connection" will appear on the Dobby display. In that case,
check that the router or mobile hotspot is online. Turn off the Dobby computer and
then turn it on again.
1. Open the Internet browser on the device.
2. If the web interface screen is still open
from the previous session, refresh the
screen.
3. Enter the IP address on the address line of
the browser. (The IP address is on the
display of the Dobby.)
or
If the device has not previously been connected
via WiFi, the Dobby password will be asked for.
This password is displayed on the Dobby display.
If the network connection is dropped, the text "No connection" will be displayed.
Once the network is available again, the connection will be automatically restored.
You may need to refresh the weaving screen by tapping the address line again.
Next, you will need to reopen the weave file. The last woven pick is always
remembered by the Dobby.
If the Dobby fails to reconnect, turn off the Dobby and turn it back on again after
about a minute. If there is no connection to the home network, check whether other
devices in your home also have a network problem.
In exceptional cases, it may be necessary to do a factory reset on the Dobby (refer
to the Dobby 2.0 Installation Manual) to rebuild the network connection.

Lift Plan
The 'lift plan' is shown on the main screen of the Dobby web interface. Each line
displays the shafts selected for that pick. The shaded boxes indicate which shafts go
up. The line showing shaft’s selected for the first pick has a dark frame around it.
Each subsequent pick is shown on the lines above it.
The box pattern is not the image of the fabric! The appearance of the woven cloth is
partially determined by the threading pattern.
The lift plan will look a little bit different depending on the edit mode or the weave.
Both screens show a Settings button, Folder button, active file name window, WiFi
connection symbol and the Louët logo with version number.

With the web interface software, you can import weaving patterns (lift plans) from a
pre-made pattern file, without commercial weaving software. There are also
websites where you can download weaving patterns. You can import and edit the
pattern if necessary.
In edit mode, you can edit the weave pattern. You can select a box (shaft to be
lifted) either by clicking in the box (left mouse button) or tapping (touch screen).
Click or tap the same box again and the selected box changes back to white.
Creating and customizing a new weaving pattern is easier with a mouse than with a
touch screen, so consider using your computer's internet browser to communicate
with the Dobby computer (following the instructions on 6. You can have multiple
devices connected to the Dobby at the same time.)
