依赖的组件，xserver安装了吗？另外，如果没有ttyACM设备的话是无法连接的。你是用的什么打印机控制板？

​ @峰哥爱鼓捣 XServer-XSDL嗎？有安裝！ 我的機器是 ANYCUBIC MEGA-S ，用樹莓派可以認到，並且在 /dev/serials 能夠看到設備序號並連線， 但是用 Android 手機則連不上，用 lsusb 可以看到裝置

@@峰哥爱鼓捣 KlipperScreen能顯示了，圖形介面沒設置好，調整好就行了，剩MCU連不上

@@chihlungchen361 ls /dev/ 命令输出的设备里能找到ttyACM设备吗？如果不能，那么可能有两种情况，一种是手机端没有ttyACM驱动，另一种是手机端有ttyACM驱动但是打印机的主板不支持。这个方案与树莓派方案在设备连接上用到不是一种方法，树莓派是标准linux系统，而手机不是，所以和树莓派有区别。主要是查看 /dev/ 路径下有没有ttyACM 之类的设备。没有就无法连接。

Hello, @JVDColin. You need to confirm the CPU model of your printer motherboard and whether its USB interface is converted using the CH340 chip. Some STM32 series CPUs and all motherboards that use CH340 as the USB interface cannot use this solution to install klipper. Because the native Android kernel is not enabled by default or there is no relevant driver at all. This is the biggest difference from the general Linux system.

哈哈，你说的对，是挺费电的。一直想找个比较省电的发动机，你有好的建议吗？

非常抱歉这么久了才回复，刚看到信息。小米2s不需要解锁Bootloader，它没有Bootloader锁，直接刷机就可以。

drive.google.com/drive/folders/15pWX5QolgwFj7ZWg8mysRCOCg-uwswJB?usp=drive_link 这是小米2s的刷机包。里边有3个文件，先通过fastboot模式刷入twrp。然后进twrp后同时刷入另外两个文件。刷机后打开手机的开发者模式，里面就会有开启root的选项。

哈哈，必须极致简单🤩

Hello, I'm glad to receive your approval. Which printer control motherboard are you using now? What is the CPU model? What is currently known is that motherboards that use the CH340 chip as the USB interface cannot be directly recognized by this solution. If you want to use it, you need to compile the firmware yourself, which is not recommended. Some STM32 CPUs cannot be recognized. Whether they can be recognized needs to be tested. Can you find your device in the output information after running ls -al /dev/ on your device? You can connect the printer control mainboard to execute the command once, disconnect the printer mainboard and execute the command again, and observe the difference in the output of the two commands. Being able to find your printer motherboard in Octo4A does not necessarily mean that it can be used in my solution. The reason is that Octo4A seems to come with its own driver. I have always wanted to find a way to implement the driver in Octo4A, but there has been no result. If you have clues, you can discuss it together.

It is this motherboard. And oh, I had assumed if it worked on a Pi that it probably worked on Android but this makes sense. The board is this one - Ender-3 V3 SE Mainboard Kit CR4NS200320C13_32_MS35774_GD303RET6 Controller - but I think it is incompatible and is a STM32F103, I could never find it when doing "ls -al /dev/" it never showed any new info when plugging in or unplugging, as well as me trying new commands to bash, using the known working serial and what Octo4A showed me. Funnily, when I used the weird Octo4A "/dev/bus/usb/001/002" I got the error about "mcu 'mcu': Unable to connect" but when I tried other things, I got "Klippy is not started" or whatever. So I think that "/dev/bus/usb/001/002" is the closest to being correct, or is correct, but it doesn't work anyway. And thanks for this reply, I greatly appreciate it @@峰哥爱鼓捣 Edit : I wonder if the part about using Octo4A here - github.com/d4rk50ul1/klipper-on-android - can be useful for making it work?

This solution is feasible, you can try it.🙂

So I did what it said with the Octo4A, Mounts and paths, changed the printer.cfg to what it said, gave Klipper the permissions with "sudo chmod 777 /home/android/octo4a/serialpipe" and skipped the rest (the scripts, since yours already had those), and it works perfectly as it should on my ZTE Axon 7. I didn't actually try printing with it yet but this phone still has a battery in it so I didn't want to take it out until I could get it working. Thanks for the great guide, info and recommendation. @@峰哥爱鼓捣

@@bettergamingchairwins2442Hi, inwant to know if what you did work or if you happen to find a way around the issue? I also have a Ender 3 v3 SE and i wanted to take a crack on giving this machine a klipper overhaul too

Most likely, no. Because as far as I know, the motherboard "MKS GEN-L V1.0" uses the CH340 chip as a bridge for USB and CPU communication. The current klipper installation solution is because the Android kernel does not enable the driver for this chip by default, so the mobile phone cannot communicate with "MKS GEN-L V1.0". There is a solution to this problem, but it requires compiling the Android kernel and replacing the original kernel. I have not studied this solution in depth, and the kernel of each model of mobile phone is different, so the specific steps for compiling the kernel are not universal. If you are interested, you can research it. If you succeed, please share your joy. Thanks for the support, bro.

@@峰哥爱鼓捣 Thanks for the informations, i will search but i don't think i will be able to do such a job unfortunately. Still you did an amazing job, congrats

I currently use ADXL345 acceleration sensor and MKS SGEN-L V1.0 printer control motherboard. I connected the ADXL345 acceleration sensor directly to the SPI pins of the MKS SGEN-L V1.0 printer control motherboard. This motherboard does not have a specially reserved SPI interface, but the SPI pins can be found on the interface connected to the screen. There are currently no problems with this connection method. If your motherboard has a dedicated SPI interface, that's even better. You can directly connect the acceleration sensor to the motherboard and then change the configuration in the configuration file.

Great work, I'm amazed how well you managed to make it so perfect. I really want to ask you a few questions, "Changed my phones power response, whenever it gets power it boots , whenever no power it shutdowns. USB camera app streams as IP Camera. I also changed a file in the kernel so phone automatically give USB automation. So I dont need any interaction. "How did you do the above? Is it convenient to provide some operation steps?

@@峰哥爱鼓捣 It doesn't give me an error message. It just says killed as soon as send the command, almost as if it's being denied or something. sudo apt update killed

@@SwiftCookie Can other commands be executed normally?

@@峰哥爱鼓捣 Nah they all get killed instantly

@@SwiftCookie This problem may be caused by insufficient system resources. Please confirm your phone's memory usage. Insufficient compatibility of some Android kernels with linuxdeploy can also cause this problem. It is recommended to try to replace the Android system, such as finding a compatible AOSP.

Are you saying that you cannot connect to the printer control board again after restarting the klipper service in the web interface? If so, I'm not currently experiencing this problem. However, if the main board of the printer is restarted alone during the running process or the connection with the MCU of the main board of the printer is lost due to other reasons, then the same problem as you will appear even if the klipper service is restarted. At this time, you need to restart the Android phone to connect. I guess it is because the Android system did not refresh the MCU status again when the klipper was restarted after the motherboard MCU was disconnected from the Android phone. Since this situation doesn't happen very often, I haven't delved into the solution. According to the operating principle of the entire system, if the MCU has been disconnected from the Android system, the MCU status can only be recognized again by restarting the Android system. After all, in this solution, klipper runs on the basis of the Android system, and the hardware driver is also based on Android.

@@峰哥爱鼓捣 Thank you for your detailed answer. I’m quite surprised when you say this doesn’t happen very often. I thought that when people don’t use their 3D printer, they turn off their 3D printer but the Android device stays on. So you mean people used to turn off the Android device too?

@@baptisteveuchau I've changed my android phone to run directly from the printer's power supply. The battery has been removed by me, and turning off the printer means turning off the Android phone at the same time. So, the situation you're experiencing doesn't happen very often on my device. Your Android phone has not been modified for power supply, right? Sorry I didn't know this before. However, in the usage scenario of Android klipper, I don't think it makes any sense to keep the Android phone on after the printer is turned off.

I have posted the issue on Github as well for your reference.

Can you provide the model of your mobile phone and the version of Android system you are using? And, what method does the Android system use to obtain root privileges? The reason for this phenomenon is likely to be the incompatibility between the kernel of the Android system and the Debian system or the container virtualized by linuxdeploy. If this is the case, you can only try to change the Android system version.

@@峰哥爱鼓捣 hi.. i am using Samsung Galaxy S8 with Android 9 (pie). I have used the TWRP method to access the root privilege. I also had the thought of re rooting the phone so doing it right now. Will surely update you once I succeed 😊

@@BassBoostedWorld I also don't know how to compile the kernel, but I plan to learn it.

@@峰哥爱鼓捣 oh okay but how your phone got connected to printer easily?

@@BassBoostedWorld My motherboard model is MKS SGEN-L V2.1, and the CPU model it uses is LPC1768, which can be directly recognized and driven by the Android system. It is said that because it was once widely used as a car chip, as we all know, most of the current car systems are developed and customized based on the Android system. So maybe the Android system has a built-in driver.
