Part 1: Ender 3 Not Reading SD Card: Why Does it Happen?

Before getting straight to fix the Ender 3 not reading SD card issue, it's important to first understand why it happened.

Well, several factors can contribute to this problem, such as:

• SD Card Format Compatibility: One common reason for this issue is the format of the SD card. Ender 3 is known to be somewhat picky about the format it can read. If the card is not formatted correctly, the printer won't be able to access the files.
• File System Error: Sometimes, the file system on the SD card can become corrupted, making it unreadable by the printer. This can happen due to improper ejection or sudden power loss during data transfer.
• Damaged or Dirty SD Card Slot: Physical issues can also cause the Ender 3 to have trouble reading the SD card. A damaged or dirty SD card slot can hinder the connection and prevent the printer from recognizing the card.
• SD Card Size: Ender 3 3D printers typically support SD cards with a capacity of 64GB or smaller. If you use an SD card that exceeds this limit, it may not be recognized by the printer. Ensure that the SD card you're using falls within the supported size range.

By understanding these potential causes, you can better diagnose and fix the Ender 3 not reading SD card problem.
