3. Plug in the power cord, turn on the power switch, and wait about 30 seconds
4.Insert the USB flash drive into the USB port on the printer.
5.Wait for 2-3 minutes, and the printer will enter the main interface smoothly after the upgrade is successful
（If you still can't enter the system after waiting for more than 5 minutes, please put the "Sovol_Update_Package-06-05_2-4-9-eddy" file in the USB flash drive to upgrade, or if it doesn't work, please contact "SOVOL"）
¶ Debugging
(1) Use the knob to select "Get ldc current" in "Advanced"
 |
 |
(2)Use the knob to select "Calibrate Eddy" in "Levelling"
 |
 |
Note: Be sure to follow the order！
Once the operation is complete, you can start printing.
If there is an alarm during eddy current calibration, you need to go to mainsail to check the alarm message.
¶ Preparation (skip if connected)
(1)Insert the USB flash drive, find the "wifi.cfg" file, open it with a text editor, and replace it with
Current WiFi name and password (Note: WiFi name cannot contain special characters,
Otherwise, it will not connect properly):
•ssid= WiFi name
•password= WiFi password
(2)Save the "wifi.cfg" file, making sure it remains in the root directory of your USB drive
(3)Plug the USB flash drive into the printer and wait for 1 minute, then press the knob
Select "Show IP" and wait 5-10 seconds. The IP address of your home network will
Appear. If 127.0.0.1 appears, we need to check whether the Wi-Fi account and password are there
Whether the USB flash drive files are correct, or whether the USB flash drive is inserted correctly, and
Then restart your computer to do the above again.
(4)If you still can't connect, go to the following website (Note: If it still doesn't work, please contact SOVOL)
https://wiki.sovol3d.com/en/SV08-Troubleshooting/Unable-to-connect-to-WIFI
(5)If you don't have a "wifi.cfg" file in your USB drive, you can create one:
•Right-click the desktop and select New > Text Document to create a new TXT file.
• Rename this file to "wifi.cfg" with a lowercase extension.
•When prompted to confirm the file extension change, click Yes, effectively creating a new .cfg file.
(6)After the printer successfully connects to the network:
Select “Show IP” on the touchscreen to retrieve the printer’s network IP address.
Enter this IP address into a web browser on a computer or mobile device within the same LAN to access the Mainsail interface.
¶ Formal commissioning
1.If the alarm message is "123", you need to enter the printer.cfg file
2.Scroll to the bottom to observe whether the number after = in "#*# reg_drive_current=" is 22, if not, change it to "#*# reg_drive_current=22" (Note: If 22 is still not available, please contact SOVOL)
3.Re-calibrate the eddy current, and after the calibration is passed, you can start using the printer.
