Using a relatively old TV Box (MXQ Pro 4K) as a 3D Print server with OctoPrint and Klipper

What do I need?

• An TV Box (I am using a MXQ Pro 4K model)
• Screwdrivers
• Linux or WSL
• SD Card
• SD Card Reader

Installing Linux on TV Box

• Open your TV Box and search for some board info (In my case, the board ID is 329Q)
• Remove the CPU heatsink and write down the CPU model (In my case, it is a Rockchip RK3228a)
• Search on how to setup a Linux on your board model or on your CPU model
• In my case, I am following this guide: CSC Armbian for RK322X TV Boxes
  • My board is using a NAND memory instead of an eMMC memory, according to the MultiTool. You can confirm by selecting the option to burn a image in the MultiTool tool itself and observing the name of the internal memory.
  • So, I just followed the instructions on the Quick installation instructions on NAND section.
  • I also choose the Minimal Debian Buster with Legacy Kernel (Legacy Kernel is required for the RK3228a processor)
• After that, you will have a fully functional Linux running on your TV Box!
• Remember to setup WiFi connection. I recommend the nmtui utility.

sudo apt update
sudo apt install python-pip virtualenv build-essential g++ python-dev git
