1. What is a Fluidd?
Fluidd in lightweight alternative to Octoprint offering the same capabilities (if you forget that Octopint plugins have ever existed). It can also run on older and less powerful Raspberry versions.
I prefer it over the Octoprint due to the better user exprience and Klipper friendly options and settings.
Please note that this guide is for a new (clean) installation.
2. Hardware requirements
You will need:
Micro SD (SDHC) card with at least 8GB capacity
Micro SD card reader
5V power source (3A for Raspberry Pi 4)
USB cable (USB-C for Raspberry Pi 4, micro USB for older versions)
WiFi network or a standard LAN network + cable
I would also recommend:
Fan for active cooling
The easiest way to get all parts is buying a complete set such as this one:
3. Download and install recommended programs
3.3. Download and install Advanced IP Scanner
This program will be used for locating Rasperry in your local network.
It is not possible to connect to Raspberry via SSH without the correct IP address.
Click here to download.
4. Prepare Raspberry
4.2. Install the case/cover
Install the Raspberry into the desired place / case / cover.
I have a designated place in my electronics compartment, so I will not use the original case.
5. Download and flash FluiddOS
6. WiFi settings (optional)
6.1. Remove and insert the micro SD card into your computer
Micro SD card is automatically safely removed after tha flash.
Remove the micro SD card from the reader and insert it again.
6.5. Set your country code
Open this ISO3166 country list and fill in your country code.
For example: I live in the Czech Republic, so my country code is CZ.
Do not forget to save the file and safely remove the micro SD.
7. First boot
8. Installation verification
8.1. IP address localization
Start with locating Raspberry in your local network.
I highly recommend installing Advanced IP Scanner CLICK HERE.
Default IP range is usually 192.168.0.1-254 or 192.168.1.1-254.
Locate the Raspberry’s IP address and copy it.
You can simply copy the IP address or default local address: http://fluiddpi.local into the browser and open the Fluidd interface.
9. Next possible steps
You have succesfully installed Fluidd.
The next logical step would be to flash your board and create a printer configuration file.
9.1. KIAUH installation
10.1. I cannot find the device in my local network
10.1.1. Invalid IP range
The most common problem is a different IP address range.
For example: you are not able to locate any device on this range: 192.168.1.1.-254
So open network settings – click on the network / more informations and find your computer’s IP address.
As you can see, this IP address in in a 192.168.0.1.-254 range.
Fill in the correct IP address range 192.168.0.1.-254 and click on Scan.
