Quick start

1. Download & install firmware.bin from here (or build your own from this repo to ensure versions compatibility)
2. Install APK from Releases tab
3. Allow all the permissions required
4. Add printer instance (Click generic-***.cfg if your printer is not available)
5. Click start
6. Go to web server's url http://IP:8888/
7. Configure serial port from "Devices" tab in web editor (1.0.1+ configures automatically if you use single printer setup)
8. You're awesome!

Can I use device as regular after I install Beam Klipper to it?

Yes! You definitely can!

Beam Klipper does not do anything to your Android system, it runs in user-space as a regular Android app

What's IP:port?

It's displayed on main page when any of the instances are running.

Web server URL is: http://IP:8888/

Camera URL's are:

• /webcam/?action=stream => http://IP:8889/
• /webcam/?action=snapshot => http://IP:8889/snapshot

Recommended camera config is mjpeg-stream (Not adaptive mjpeg) for Fluidd and UV4L-MJPEG for Mainsail

What's inside?

Beam Klipper bundles:

• Klipper
• Moonraker
• Fluidd
• Mainsail
• Happy Hare
• Klipper TMC Autotune
• Moonraker-timelapse

Beam extensions

Beam Klipper provides additional extensions to control some built-in features.

Camera

Include [beam_camera] into your printer.cfg

SET_CAMERA_FLASHLIGHT ENABLED=true/false - Toggles flashlight

SET_CAMERA_FOCUS AUTOFOCUS=true/false FOCUS_DISTANCE=0...? - Sets camera autofocus state and focus distance if autofocus is disabled. FOCUS_DISTANCE is expressed in dioptres, it may vary from device to device

Beeper

Include [include beam_beeper.cfg] into your printer.cfg

Use M300 macro as defined in docs

Autostart

You can put the app to autostart by setting needed printers to autostart AND setting app as default launcher.

You must remove lockscreen pincode if your device is encrypted (Enabled by default on most devices)

Background activity notice

Some manufacturers may restrict app's performance or background process. You can circumvent this by setting app as default launcher and allowing all the background tasks

Android TV support?

It should be supported, but it's not tested yet. There might be interface bugs

What USB hub to use?

I'm using UGREEN Type-c hub (Not affiliated, but I'm waiting for your request UGREEN :D), but any should be fine if it works with your device and provides charging at the same time

Restrictions

• Web server can't run on default port because Android/linux doesn't allow user-space apps to bind to ports less than 1024 and we want 80 for default http://IP
• Only up to 4 instances can be running at the same time because Android requires developer to declare each service with different process individually. Idk if someone will use more than that anyway ¯\_(ツ)_/¯
• Some devices may reset device path on firmware restart, you should use VID/PID naming in that case
• No SSH (You won't be able to build firmware or run additional autorun services anyway)
• Some devices doesn't support OTG and charging at the same time, you must solder directly to the battery pins in that case (Or use different device, it's up to you)
• Only 250000 baud rate is supported (I don't want to forward this setting into Android USB driver, almost all configurations use 250000 anyway)

Building

• Fetch all of the submodules first! (git clone --recursive, do NOT download project as archive)
• Import project into Android Studio & click run

Contributing

Pull requests are welcome, but I will NOT approve Kotlin source code as I don't use it in my projects
