¶ 🪄 Preparation
Before starting troubleshooting, let's first understand how the two connection modes work:
¶ Could Mode (Remote Connection)
When connecting to the device via cloud mode, Snapmaker Orca needs to send commands from your computer to the official cloud server over the internet, which then forwards them to the device. This means both your computer and the device need to have proper internet access. In most home networks, this requires a router. Therefore, it is recommended to check your network connection, including the router, computer network, and cloud server status.
¶ LAN Mode (Local Connection)
If your computer and the U1 printer are connected to the same Wi-Fi network provided by the same router, data will be transmitted internally without passing through the internet, and information is stored only locally on the computer. The workflow is: Computer → Router → Device. In this case, it is necessary to check the status of the router, computer network, and printer separately.
¶ 🛠️ Troubleshooting Steps
¶ Scenario 1: Disconnected in Cloud mode
¶ Step 1: Check Router Status
Touch the exterior of the router with your hand:
- If the router feels warm or slightly hot, it indicates normal status. You may proceed to Step 2 for further troubleshooting.
- If it feels too hot to touch and you can't keep your hand on it for long, it indicates the router is overheating. In this case, it is recommended to unplug the router and wait for 5 minutes to allow it to cool down. Then plug it back in and restart for a refresh test.
Router overheating is often a sign of unstable performance. This is typically accompanied by increased network latency or lagging on other devices connected to the same Wi-Fi.
¶ Step 2: Check Computer Network Connection
Check if the computer’s Wi-Fi connection is working properly:
- If not, restart the computer to ensure the Wi-Fi connection is functioning correctly.
- If the connection is normal, restart Snapmaker Orca or try unbinding and then re-binding the device.
¶ Step 3: Check Cloud Server Status
If everything above seems normal, the issue may lie with the cloud server. Use the built-in network testing tool in Snapmaker Orca to check the connection status between the server and the software:
Snapmaker Orca V2.2.1 and above versions have added the network testing functionality. For better experience, please update the software to the corresponding version first.
- Open the menu bar > Click
Help> SelectOpen Network Test.
- Click
Start Test Multi-Threadand enter the device's IP address.
- Review the test results.
- If the problem persists, please export the U1 log files and Snapmaker Orca log files, along with any screenshots or videos taken during the troubleshooting process, and reach out to Snapmaker support for professional technical assistance.
¶ Scenario 2: Disconnected in LAN mode
¶ Step 1: Check Router Status
Touch the exterior of the router with your hand:
- If the router feels warm or slightly hot, it indicates normal status. You may proceed to Step 2 for further troubleshooting.
- If it feels too hot to touch and you can't keep your hand on it for long, it indicates the router is overheating. In this case, it is recommended to unplug the router and wait for 5 minutes to allow it to cool down. Then plug it back in and restart for a refresh test.
Router overheating is often a sign of unstable performance. This is typically accompanied by increased network latency or lagging on other devices connected to the same Wi-Fi.
¶ Step 2: Check Computer Network Connection
Check if the computer’s Wi-Fi connection is working properly:
- If not, restart the computer to ensure the Wi-Fi connection is functioning correctly.
- If the connection is normal, restart Snapmaker Orca or try unbinding and then re-binding the device.
¶ Step 3: Check Printer Status
If everything above is normal or the issue persists after restarting the router, computer, and the software, the problem may lie with the printer.
- On the touchscreen main interface, navigate to the Settings page > Tap
Wi-Fi> Check if an IP address is displayed at the bottom.
- If no IP address is shown, scroll to the bottom of the Wi-Fi page, select
Enable Maximum Compatibility, and then tapScanagain.
- If the device still fails to connect, try restarting the printer or performing a
Factory Reset.
- If the problem persists, please export the U1 log files and Snapmaker Orca log files, along with any screenshots or videos taken during the troubleshooting process, and reach out to Snapmaker support for professional technical assistance.
¶ ✅ Verification
After completing the above troubleshooting steps, refer to the Snapmaker Orca Quick Start Guide for U1 to rebind the printer:
- Bind via PIN code: If the following interface appears in Cloud mode, it indicates a successful connection.
- Bind via IP address: If the following interface appears in LAN mode, it indicates a successful connection.
