Welcome to FreeDi

FreeDi is a complete 3D printer firmware solution built on official, unmodified mainline Klipper for QIDI printers.
The goal of this project is to give you the ownership of your printer, so you can do whatever you want with it.
Update, enhance, tuning, modifying? FreeDi has you covered!

The foundation runs on an open operating system (Armbian) with transparent, community-driven Klipper at its core. Originally developed for the QIDI X3 series (X-Smart3, X-Plus3, X-Max3), FreeDi now supports additional models including the Q1 Pro and Plus4.
The install process is as simple as possible, because we don't want to lock out beginners.

Software only

FreeDi is a software/firmware project. It can improve performance, stability, and usability - but it cannot fix underlying hardware issues. If your printer has a mechanical or electrical defect, FreeDi won't change that.

Why Users Choose FreeDi

FreeDi is more than just a firmware update - it's a complete ecosystem that makes your printer better, faster, and safer.

Many users switch to FreeDi not just for the features, and here are the reasons why:

  • Full access to the Klipper ecosystem - use modern plugins like Cartographer, Beacon, Shake&Tune, Spoolman, and more without compatibility issues (stock systems run OS and Klipper versions up to 4 years old, making updates nearly impossible without expert knowledge)
  • More storage space for your prints - FreeDi provides ~2.6GB of free space on an 8GB eMMC compared to stock's ~500MB, eliminating the frustration of running out of room for your favorite addons & gcode files
  • Security First: FreeDi passes security audits that stock firmware fails - critical for users in security-sensitive environments
  • The open Klipper foundation provides transparency and community support - no proprietary forks
  • System updates keep pace with the latest Klipper improvements
  • Enhanced Performance: Numerous improvements that deliver better print quality, faster operation, and increased reliability
  • The responsive display and refined UI make daily printing more enjoyable - noticeably faster than stock with a dedicated communication layer ensuring a smooth reliable interaction.
  • One-Click Updates: OTA update mechanism keeps everything current with minimal effort
