QIDI continuously improves their printers - which is great! However, they don't update version numbers when hardware changes. This means your QIDI printer likely has unique hardware combinations that differ from other "identical" models.

This is why creating a backup of your exact system configuration is critical before installing FreeDi.

FreeDi cannot provide a one-size-fits-all configuration because:

• Silent revisions: QIDI releases multiple batches with hardware changes but identical model names and version labels
• Widespread variations: Differences exist in mechanics, print beds, probes, toolheads, stepper drivers, mainboards, and more
• Inconsistent labeling: Even mainboards with the same label (e.g., "X-6 V1.0") can have different components and wiring

Without your backup, you may lack critical information needed to configure your specific hardware correctly.

Below are two mainboards, both labeled "X-6 V1.0" - yet they have fundamentally different fan configurations:

User's Mainboard (hypdal) - labeled "X-6 V1.0"	User's Mainboard (hypdal) - FAN2 Port
My Mainboard - labeled "X-6 V1.0"	My Mainboard - "Always On" Fan at Same Location

Key difference: One board has a controllable FAN2 port, the other has an "always on" fan. Same label, completely different behavior. More details in GitHub Issue #8.

• First batch: Different mechanics, print bed designs, and probe types
• Later batches: Updated toolheads and stepper drivers
• Mainboards: Multiple revisions labeled "X-4 V1.0" and "X-6 V1.0" with internal differences
• And likely more variations we haven't discovered yet or that QIDI will introduce in future production runs

Bottom line: Your backup is your safety net. It ensures you can always reference your exact hardware configuration and revert if needed.
