Got an old RPIzero you picked up awhile back to hit the limit for free shipping? Put that thing to use and get a great light weight, low cost klipper interface in the process. (helpful links and commands at the bottom)

1. Swapping ports used by GPIO and Bluetooth
sudo nano /boot/config.txt
Move the cursor to the very end and add:
dtoverlay=pi3-miniuart-bt
2. Disabling the serial console
sudo nano /boot/cmdline.txt
Look for following string (text) and delete it
console=serial0,115200
3. Raspi-config stuff
sudo raspi-config
Go to 'Interfacing Options'
Then P6 - Serial
Then No
Then Yes
Then go down to finish and reboot.
4. Rebuild your Klipper MCU firmware, unselecting "Use USB for communication (instead of serial). Flash updated firmware to your board
5. Update your printer.cfg:
serial: /dev/ttyAMA0

For those curious about the initial changes in SSH, the Pi has two types of UART... Hardware, and software. By default the Pi uses the hardware UART for Bluetooth, and leaves the software UART available on the GPIO parts. Those commands enable the HARDWARE UART on the GPIO pins, so that Klipper has direct hardware access instead of emulated UART via software. This is especially important on a Pi Zero W, as it's already low on processing power, and software UART would cause further issues.

@SittingDuc 3 жыл бұрын

Also, hardware UART guarantees 115200 baud; Pi a with Bluetooth have a (bad) habit of making the Bluetooth modem perfect frequency, while the software UART is a few Hz off. Sadpanda.

Great video! With a little tinkering to the printer.cfg file i was able to get my SKR Mini E3 V1.2 with BL-touch and an Ender-extender 300 kit set up with Klipper and Mainsail. This video helped tremendously. The actual MainsailOS install part was easy, but the part where i had some digging to do was at 9:41 . Needed to ensure that i am choosing the correct UART on the board (SKR documentation lists which pins are which UART port) and then following the instructions in the Klipper Printer config file comments section. Once that part was done it was copy, paste, adjust for externer300 size, rename, print a test. Worked out perfectly and i got rid of a lot of the cable mess! Will be doing it for my RatRig once it comes in, and going the UART route as well! (unless there is a good reason not to?) Thank you, Thank you, Thank you!!!

Just a note on the connection between the pi and printer board, in this case both use 3.3V for logic, but for example ramps 1.4 and other arduino based boards usually use 5V for logic, so you will need to add some sort of a voltage devider so you don't fry your pi. Otherwise great idea and I'm definitely giving it a try

It's worth pointing out I think that you can make the Pi Zero work entirely over USB too so that you can preserve the ability to use the display. You can even power the device via the USB port too. All you need to do is place a jumper wire from the 5V power line (can be taken from many jumpers on the printer board) and place it to the USB power line, which is also probably attached to a jumper. Then the Pi powers and communicates via USB and all you need is a micro > USB A adaptor and then a standard USB cable. I've got it working this way even with a Pi Zero that doesn't come with wifi. The USB port on the Zero connects to a micro>A adaptor and then plugs into a small USB hub. The Pi and Wifi dongle then plug into the hub.

Even with PA and input shaping enabled it pretty much always show 30-40% idle in top while printing and streaming video.

Hello, I tried this method with my Pi Zero W and an SKR Mini v1.1 to try to get around an issue I was having with the serial connection. I've established klipper settings well enough that with a pi 3b+ connected via usb to the board, the pi established connection with the MCU. But with the same pi card in a pi zero W, I have not been able to get it to recognize the MCU via USB or UART... I have tried a different pi Zero W and it also didn't work, so it appears to be an issue with the platform, not the individual board.

However I don't want to have to perform surgery on the board to bypass that, so can I still use the RPi zero USB to connect to the printer? It would mean not changing the serial settings on the pi as you showed. I'd need a USB cable between the printer and the Pi, but I can live with that, if the extra CPU load of the UDB serial driver isn't a problem.
