How to Update the Firmware on Your Ender 3 S1 Pro: A Step-by-Step Guide

One common question I’ve received recently is how to update the firmware on the Ender 3 S1 Pro. This blog post will walk you through the entire process, highlighting important considerations and potential pitfalls. Let’s dive in!

Why Update Your Firmware?

Updating the firmware on your Ender 3 S1 Pro brings several benefits, primarily new features. For instance, if you have the laser engraving module, the newer firmware allows seamless switching between the printer head and the laser engraving head. Even if you don’t have this module, keeping your firmware updated ensures you have access to the latest features and improvements.

Risks and Precautions

Before proceeding, it’s important to understand the risks. Firmware updates can potentially “brick” your printer if something goes wrong, such as a failed or interrupted update. However, I’ve personally updated my firmware multiple times without any issues. Proceed with caution and at your own risk.

What You’ll Need

• Computer with Internet Access: To download the firmware.
• Media for Firmware Transfer: An SD card and a Micro SD card (8GB or less is recommended). You can use a larger card, but you’ll need to partition it to 8GB.

Preparation

1. Check Current Firmware Versions: Navigate to Settings > About on your printer to note the firmware and screen versions. Take a picture for reference.
2. Identify Your Printer’s Chip Version: Unplug the printer, remove the bottom cover, and locate the chip. It’s either a 401 or a 103. This will determine which firmware version you need.

Partitioning an SD Card (If Needed)

If your SD card is larger than 8GB:

1. Open Disk Management: Press Windows + R, type diskmgmt.msc, and hit OK.
2. Delete Existing Partition: Right-click on your SD card and select “Delete Volume.”
3. Create a New Partition: Right-click the unallocated space, select “New Simple Volume,” and set the size to 8000 MB.
4. Format the Partition: Right-click the new volume, select “Format,” choose FAT32, and set the allocation unit size to 4096 bytes.

Downloading and Installing the Firmware

1. Download Firmware: Visit Creality’s official website, navigate to Downloads > Firmware, and select the latest firmware for Ender 3 S1 Pro.
2. Extract Firmware Files: Use WinRAR to extract the downloaded .rar file to your desktop.
3. Prepare SD Card for Display Firmware:
   • Copy private, DWIN_SET, and firmware.bin files to the SD card.
   • Insert the SD card into the display, reconnect it, and turn on the printer to start the update.
   • Once updated, remove the SD card.
4. Prepare SD Card for Mainboard Firmware:
   • Delete previous files from the SD card.
   • Copy STM32F4_UPDATE.bin to the SD card.
   • Insert the SD card into the printer and turn it on to start the update.

Final Steps

1. Verify Update: After the printer restarts, navigate to Settings > About to check the firmware versions.
2. Remove SD Card: Turn off the printer and remove the SD card.
