No User Folder - Firmware Recovery
Firmware updates are essential for maintaining optimal performance and accessing new features. However, if essential files are lost or corrupted during an update, your machine may fail to start or operate correctly. This guide provides a detailed procedure to recover your machine by reinstalling firmware from the SD card and restoring normal operation.
Before you begin - safety and risk
Read the Safety - Before You Begin article to understand the hazards involved in working on the Vision Miner 22IDEX V4 - including electrical, thermal, mechanical, and chemical risks. All procedures in this wiki are provided as recommendations only. By choosing to follow any procedure, you do so at your own risk.
Symptoms
Common symptoms indicating missing or corrupted firmware files include:
- Machine fails to start or power on after a firmware update
- LED lights inside the machine remain off after powering on
- Error messages appear indicating missing variables or files when attempting to operate the machine
- Web Interface shows errors about missing system files or folders
These symptoms suggest that crucial system files (particularly the user folder) are missing, and the machine cannot operate normally.
Firmware Recovery Procedure
- Power off the machine. Unplug the machine completely from the power source to prevent electrical issues during SD card removal.
- Locate the SD card slot. Find the SD card slot on your machine's mainboard or control panel.
- Remove the SD card. Gently remove the SD card from the slot.
- Insert SD card into your computer. Use an SD card reader to connect the SD card to your computer.
-
Back up existing files (optional). If you have custom macros or settings, copy them to a backup folder on your computer before erasing the SD card.
-
Erase all files on the SD card. Delete all files and folders on the SD card to ensure it is completely empty.
- Download the correct firmware. Identify your machine model and download the corresponding firmware package:
- V3 firmware
- V2 with Y-axis endstops
- V2 without additional endstops
- Extract the firmware archive. Unzip the downloaded firmware file. You should see the following folders: user, macros, sys, filaments, firmware, gcodes, and www.
- Copy folders to SD card. Move all extracted folders to the empty SD card. Ensure all folders are copied correctly.
- Verify SD card contents. Ensure only the specified firmware folders are present on the SD card with no extra or missing folders.
-
Safely eject the SD card. Use your operating system's eject function to prevent data corruption before removing the SD card.
-
Reinsert the SD card into the machine. Place the SD card back into the machine's SD card slot, ensuring it is fully seated.
- Reconnect power and turn on the machine. Plug the machine back into the power source and turn it on. The machine should start normally with the restored firmware.
Network Configuration
For Wi-Fi equipped machines, after firmware recovery, the machine will restart in Access Point mode.
- Connect to the machine's Wi-Fi network. On your device (phone, tablet, or computer), find the Wi-Fi network named "22IDEX" and connect to it.
-
Enter the Wi-Fi password. When prompted, enter the password:
1234567890 -
Open the Web Interface. Open a web browser and navigate to
http://192.168.0.1.
- Configure permanent network connection. To connect the machine to your existing Wi-Fi network, navigate to Macros > System > Settings > WiFi > Connect to My WiFi Network in the Web Interface.
- Enter your Wi-Fi credentials. Enter your Wi-Fi network SSID (network name) and password when prompted, then click OK to confirm.
- Verify connection. Observe the LED indicators on the machine. Green LEDs indicate successful connection. Red LEDs indicate connection failed - retry if necessary.
Calibration Procedures
After firmware recovery, your machine's critical parameters have been reset. Do not attempt to print before completing these calibration steps.
- Verify Z-probe is docked. Ensure the Z-probe is in its dock at the back of the machine before starting calibration.
- Calibrate Z-probe pickup angle. Navigate to Macros > System > Calibration > Z Probe > Rotate Holder to a Set Degree. The holder rotates to the default position.
- Adjust the pickup angle. Use the "Adjust Pickup Angle Clockwise" or "Adjust Pickup Angle Counterclockwise" macros to adjust the angle. Aim for the Z-probe to be horizontal with magnets facing upwards, parallel to the magnets on Tool 0.
- Calibrate Z-probe pickup position. Select Macros > System > Calibration > Z Probe > Adjust XY - Pickup Position. The machine will home the Y, X, and U axes.
- Align the tool with the docking station. Use the on-screen prompts to move the tool left/right and forward/backward until the tool is perfectly aligned with the docking station.
- Test the probe pickup. Click OK to perform a self-test. Observe if the probe is picked up correctly.
- Calibrate Z-probe offset. Navigate to Macros > Z - Offset Calibration and follow the on-screen prompts.
- Adjust nozzle height. Place a piece of paper under the nozzle and adjust the nozzle height until you feel slight resistance when moving the paper.
-
Save the calibration. Save the Z-offset settings when prompted.
-
Verify tool height calibration. Ensure both Tool 0 and Tool 1 are correctly calibrated for height before printing.
-
Perform second tool XY calibration (if needed). If you plan to use mirror, duplicate, or multi-material modes, perform the second tool XY calibration from the calibration macros.
