klipper4a (chroot install script)

this script is for easy install kilpper gui (fluidd or Mainsail) for android based on alpine-klipper

requirements

• phone (rooted)
• sd card
• custiom kernel (sometimes if not support by serial drivers)
• chroot (I recomend linuxdeploy)
• otg cable or usb hub

set linuxdeploy

• select distribution (alpine)
• Distribution suite (last-stable[if you want compile kilpper on a phone])
• set password
• enable ssh if you use debian set image size in the settings menu
• check Lock wifi
• check Wake lock
• in top right corner menu click install

login to ssh

sudo apk add bash curl #if you use alpine
curl -O https://raw.githubusercontent.com/Zlywilk/klipper4a/master/moonraker-android.sh

• edit script using your favorite editor to add printer config (if you want nano use "sudo apk add nano")
• set serial to "$SERIAL"
• run script

bash moonraker-android.sh

after reboot

• start conteiner and run script

./start.sh

Future features

• write script for auto update if serial is changed
• add update support for alpine in moonraker
• write debian script
• write native app for android

camera support

if you have existing installation edit file /etc/nginx/http.d/default.conf (alipine) change from

listen 8080 default_server;

to

listen 8085 default_server;

and add to start.sh line after #!/bin/bash

sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8085

now you can vist gui at port 80

accelerometer

if you use accelerometer set line 237

and after evry restart run command

sudo chown -R "$USER":"$USER" /dev/ACM0 #your path to device

method 1(use low resources but sometimes brake stream)

download IP Webcam form play store

start ip webcam server

set camera url to /webcam/video

method 2

download CamON Live Streaming form play store

start CamON server

set camera url to /webcam/video/mjpeg

obico(SpaghettiDetective)

first you must config and run camera in background if you run existing instalation simply run

bash obico.sh

if you run fresh install you must remeber run camera in backgraund otherwise you don't get install promt

FAQ

Q: why root?

A: there is one method (proot) which you can run linux on android whitout root but doesn't support mmap which is essential to run moonraker
