+# MainsailOS install
+
+## Image
+
+Start with MainsailOS from Raspberry Pi Imager install
+
+## Driver update
+
+Run `rpi-upate` to get at least kernel 6.6 and update camera driver
+
+## Configuration files
+
+Copy over configuration files from this repo to `~/printer_data/config/`
+
+## Set up Klipper firmware
+
+Check `~/printer_data/config/printer.cfg`, `[mcu]` section:
+
+```ini
+[mcu]
+serial: /dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0
+baud: 250000
+```
+
+`250000` is fastest transfer supported by Ender 3 board.  It needs to match baud setting in `make menuconfig` low-level settings.
+
+```shell
+cd ~/klipper
+make clean
+make menuconfig
+make
+make flash FLASH_DEVICE=/dev/ttyUSB0
+```
+
+(seems to work better than `make flash FLASH_DEVICE=/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0`)
+
+Flashing fails sometimes.  Possible workarounds:
+
+- Klipper app is still talking to device?  Shutdown firmware and app first?
+- `/dev/ttypUSB0` and `/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0` are links to same device, but one works and other doesn't?
+- Try rebooting Pi
+
+## /boot
+
+Copy `config.txt` and `cmdline.txt` from this repo.
+
+## Zabbix agent
+
+```bash
+cd
+wget https://repo.zabbix.com/zabbix/7.0/raspbian/pool/main/z/zabbix-release/zabbix-release_7.0-1+debian11_all.deb
+sudo dpkg -i zabbix-release_7.0-1+debian11_all.deb
+sudo apt update
+sudo apt install zabbix-agent2
+```
+
+Update `/etc/zabbix/zabbix_agent2.conf` from `zabbix/zabbix_agent2.conf` in this repo.
+
+Confirm `/etc/zabbix/*` files are owned by `zabbix:zabbix`.
+
+```bash
+sudo systemctl restart zabbix-agent2
+sudo systemctl status zabbix-agent2
+```
