Hello! Let's learn how to update your 3D printer's firmware and how to ask for help if you need it.

Error Analysis

The "cold extrusion prevented" error occurs when a 3D printer's firmware blocks extrusion because it detects that the nozzle temperature is below a predefined threshold. This safety feature is designed to prevent damage to the extruder and ensure proper filament flow. To troubleshoot this issue, consider the following steps:

1. Verify Nozzle Temperature Settings:

   • Check Printing Temperature: Ensure that your slicer settings specify an appropriate temperature for the filament you're using. For instance, PLA typically prints around 190-220°C, while ABS requires 220-250°C. If the set temperature is below the filament's recommended range, the firmware may block extrusion.
   • Monitor Temperature Stability: Observe the nozzle temperature during printing to confirm it reaches and maintains the target temperature. Fluctuations or failure to reach the desired temperature can trigger the error.

2. Check for Firmware Errors:

   • Error Messages: Some users have reported receiving "cold extrusion prevented" errors due to firmware glitches or communication issues. If the printer's temperature readings are stable and correctly configured, yet the error persists, consider updating or reinstalling the printer's firmware.

By systematically checking these aspects, you can identify and resolve the cause of the "cold extrusion prevented" error, ensuring smoother and uninterrupted 3D printing operations.

What is Firmware?

Firmware is like the brain of your 3D printer. It tells the printer how to move and create objects. Sometimes, updating the firmware can make your printer work better.

Getting Help

If you have questions or something isn't working, here's how to get help:

1. Email Tronxy Support:

   • Write an email to TronXY Support.
   • Include:
     • Your printer's model name.
     • A description of the problem.
     • Pictures or videos showing the problem, if possible.

2. Visit the Support Center:

   • Go to the Tronxy Support Center for guides and answers.

Remember, it's okay to ask for help. Updating firmware can be a great way to learn more about your 3D printer!

Updating the Firmware

Updating the firmware of your Tronxy Crux 1 3D printer can enhance its performance and resolve potential issues. Here's how to proceed:

1. Identify Your Printer's Mainboard Chip:

The Crux 1 may have either an STM32F446ZET6 or GD32F4xx mainboard chip. To determine yours:

• Via the Printer Menu: Navigate to System > Info on your printer. If "GD32" appears, your printer uses the GD32F4xx chip. If not, it likely uses the STM32F446ZET6 chip.

• Physical Inspection: Alternatively, open the printer's casing and inspect the mainboard directly. The chip will be labeled with its model number.

2. Download the Appropriate Firmware:

Once you've identified your chip, download the corresponding firmware:

• Official Firmware: Tronxy provides firmware for both chip types on their website.

  • For STM32F446ZET6:

  • For GD32F4xx:

• Open-Source Firmware: If you prefer open-source options, Tronxy offers firmware on their GitHub repository.

3. Prepare for the Update:

• Format an SD Card: Use a blank SD card formatted to FAT32.

• Create an 'update' Folder: On the SD card, create a folder named update.

• Copy Firmware Files: Place the downloaded firmware files into the update folder.

4. Update the Firmware:

• Power Off the Printer: Ensure the printer is completely turned off.

• Insert the SD Card: Place the prepared SD card into the printer's SD card slot.

• Power On the Printer: Turn the printer back on. It should automatically detect the new firmware and initiate the update process.

• Wait for Completion: Allow the printer to complete the update. Once finished, it will restart, and the new firmware will be active.

5. Verify the Update:

• Check Firmware Version: After the update, navigate to System > Info to confirm that the firmware version matches the one you installed.

Important Considerations:

• Backup Settings: Before updating, note your current printer settings, as the update may reset them to defaults.

• Compatibility: Ensure the firmware version matches your printer model and mainboard chip to prevent potential issues.
