I use Octoprint as a print server and also use the plugin Octorelay to control the light and ventilation in the printer housing.
For my Prusa MK4S / Tukkari TLX housing some modifications have been required:
- LED nozzle light (Nozzle light Prusa MK3S+ von steffanders | printables.com )
- Tukkari LED light (LED Rail for Tukkari case Prusa MK3S von Gpower-Design | printables.com)
- 5V USB fan (12cm diameter) for Tukkari enclosure/HEPA filter (120mm fan | printables.com)
- 12V fan (power supply, Halter für PSU-Lüfter im Tukkari Enclose von Tom | printables.com)
My first free wiring attempt with a test board did worked well but need to had to give way to a permanent solution.
This is my today's setup with the links to potential sources of the material used:
Printserver:
- Raspberry Pi4
- Raspberry 7 inch touch screen with OneNine display housing - black (Raspberry Pi 4 Touchscreen Kit | Welectron)
- Freenove Breakout Board (FREENOVE Breakout Board | Amazon)
The Freenove Breakout Board is currently my best solution to connect the display and have access to all GPIOs at the same time. I also use it for other projects.
Items for the power supply case:
- 4 Channels LM2596 DC to DC Converter, 13-35V input (4 Channels LM2596 DC to DC Buck Converter | Amazon)
- 4 channel 5V relay modul (Penglin, PENGLIN 1PCS 4 Kanal 5V Relais Modul mit Optokoppler | Amazon)
- 24V 3A AC/DC power supply (Netzteil 24V 3A AC/DC | Amazon)
- 1x USB breakout board (USB 2.0 Breakout | Amazon)
Other:
- 8*0,14mm² cable, ~2 meter (Flachbandkabel 8-fach | eBay)
- cable terminals 0,14mm² (Aderendhülsen-Sortiment | voelkner)
- AWG26 wire, red and black
- DC mounting sockets and jack plugs for 12V, 5.5 x 2.5 (set | Amazon)
- screws M2,3x5 or equivalent (screw set | Amazon)
Have fun!
P.S. Most of the stuff I had on stock due to other DIY and smarthome projects. Please fell free to use the links attached as reference. Soldering the wires to the connectors is quite easy. I will add the connection diagram later on, too.
Update 01/2025:
As the LM2596 DC buck converter is no longer widely available and is also not powerful enough for my cabin lighting, I decided to switch to a more powerful power supply and build a housing. Check it out!:
Have fun!
