¶ 🛠️ Troubleshooting Steps
¶ Scenario 1: Device Cannot Obtain an IP Address
¶ Step 1. Check if the IP address is displayed on the touchscreen
- Go to Settings → Wi-Fi and check if an IP address is shown.
- If an IP is displayed → proceed to Step 2: Confirm Region Settings
- If no IP → try enabling Wi-Fi Compatibility Mode, then reconnect to your Wi-Fi network and check if an IP is obtained.
Maximum compatibility: Some Wi-Fi access points may have advanced features that are not fully compatible with the printer’s Wi-Fi module, causing IP acquisition failure. If you encounter connection issues, try enabling the "Maximum Compatibility" option (default off).
- If IP is still not obtained after enabling compatibility mode:
- Confirm the wireless router or access point is functioning properly (test with a computer or phone).
- Try connecting U1 to a 2.4GHz mobile hotspot to see if it obtains an IP.
If the network is abnormal, fix it before retrying the connection.
¶ Scenario 2: Device Obtains IP but Cannot Connect
¶ Step 2. Confirm Region Settings
- On the touchscreen, go to Settings → Account → Region. Select "International" for regions outside Mainland China.
- Ensure Snapmaker Orca and the device are in the same region.
¶ Step 3. Check Firewall and VPN
-
Ensure your computer firewall is not blocking Snapmaker Orca from accessing the network.
-
Ensure no VPN or proxy is active on your computer.
Images show Windows as an example. Mac or Linux users should also check firewall and VPN/proxy settings.
¶ Scenario 3: Previously Connected Successfully, Suddenly Cannot Connect
¶ Step 4. Forget the Wi-Fi Network and Reconnect
In some unexpected cases, connection failures may occur due to timeout. You can try “forgetting” the network and reconnecting.
- Long-press the Wi-Fi network for more than 3 seconds, release it → the printer will forget the network.
- Then reconnect to the Wi-Fi.
¶ Step 5. Export Logs if Issue Persists
If all steps fail, export both the printer and Snapmaker Orca logs and contact Snapmaker Support with these logs and the timestamp of the issue.
¶ ✅ Verification
-
Device successfully obtains an IP address
-
Snapmaker Orca shows “Connected” in the top-right corner
-
Snapmaker Orca successfully connects to the device via cloud mode
