Troubleshooting

My Printer connects on the app but I cannot get it to connect through Web UI

If your printer connects on the app and does not connect on the Web UI, it is usually one of two things.

I used a backup from another device/older version

The backups between different devices and Octo4a are not compatible, because there are some Octo4a specific settings that makes the devices visible to Octoprint. Fortunately, It is very easy to fix!

• Go to Settings > Serial Connection > General > Additional serial ports => /dev/ttyOcto4a

If you want to use Camera Server feature:

• Go to Settings > Webcam & Timelapse > Webcam > Stream URL => http://<your device's ip>:5001/mjpeg
• Go to Settings > Webcam & Timelapse > Timelapse Recordings > Snapshot URL => http://<your device's ip>:5001/snapshot
• Go to Settings > Webcam & Timelapse > Timelapse Recordings > Path to FFMPEG => /usr/bin/ffmpeg

There are multiple choices for serial device drivers

You can identify this case by (tap to select) the message under Printer is connected tab. Try out different drivers until it works. Every 3D printer is different, they might require different driver. It is trial and error.

The app says Installation Corrupted

Most likely you had experienced a network connection loss or you have a firewall setting blocking some files from downloading. If the problem persists after re-installation, you should try another network connection or setup a hotspot from another phone or another device.
