notes on how to multiply klipper-instances (and moonraker) to have a multi-printer setup using https://github.com/cadriel/Fluidd (and/or https://github.com/cadriel/FluiddPI)

### service startup for klipper instance 2
sudo cp /etc/default/klipper /etc/default/klipper-2
sudo vi /etc/default/klipper-2
# KLIPPY_ARGS="/home/pi/klipper/klippy/klippy.py /home/pi/klipper-2_config/printer.cfg -l /tmp/klippy-2.log -a /tmp/klippy-2_uds -I /tmp/printer-2"

sudo cp /etc/init.d/klipper /etc/init.d/klipper-2
sudo vi /etc/init.d/klipper-2
# DESC="klipper-2 daemon"
# NAME="klipper-2"
# DEFAULTS_FILE=/etc/default/klipper-2
# PIDFILE=/var/run/klipper-2.pid

### service startup for moonraker instance 2
sudo cp /etc/systemd/system/moonraker.service /etc/systemd/system/moonraker-2.service
sudo vi /etc/systemd/system/moonraker-2.service
# Description=Starts Moonraker-2 on startup
# ExecStart=/home/pi/moonraker-env/bin/python /home/pi/moonraker/moonraker/moonraker.py -l /tmp/moonraker-2.log -c /home/pi/klipper-2_config/moonraker.conf

### copy existing configuration over. please tidy up accordingly
cp -rv /home/pi/klipper_config /home/pi/klipper-2_config

### unique moonraker socket
vi /home/pi/klipper-2_config/moonraker.conf
# port: 7126
# config_path: /home/pi/klipper-2_config/klipper-2_config
# klippy_uds_address: /tmp/klippy-2_uds

### unique moonraker serial port
vi /home/pi/klipper-2_config/printer.cfg 
# [mcu]
# serial: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 # :)

### adjust 'cors' configuration for all endpoints
vi /home/pi/fluidd/config.json
# "endpoints": [
#   "http://fluiddpi",
#   "http://fluiddpi.local",
#   "http://fluiddpi.local:7125",
#   "http://fluiddpi.local:7126"
# ],

### now that the files are changed let the daemon read them in
sudo systemctl daemon-reload

### enable start on bootup
sudo systemctl enable klipper-2
sudo systemctl enable moonraker-2

### and execute!
sudo systemctl start klipper-2
sudo systemctl start moonraker-2
