This gist will help you in setting up klipper led-effects for a toolchanger setup. The code used here works with any number of tools. Make sure to write all the macros for each tool to avoid issues with jinja macro parsing (if T0_set_logo_leds doesn't exist but it's called, the macro will end up calling the T0 macro instead)

Main led effect macros

These macros are the main entrypoint, and will call tool-specific effects as necessary

[gcode_macro _set_logo_leds_off_inner]
gcode:
    SET_LED_EFFECT EFFECT=T{params.TOOL}_set_logo_leds STOP=1

I'm creating this gist mostly to help out other people in configuring and setting up spoolman to both:

allow setting a spool for each tool
handle spool switching and state management

My examples use two tools since that's what I have right now

first off (assuming you have a working spoolman integration running already, as well as [save_variables] set up) you'll need to set spool support for each tool

[gcode_macro T0]
variable_active: 0

	#!/usr/bin/env python3
	import sys
	import re
	from math import sqrt

	preheat_time = 15.0 # Preheat a tool this many seconds before its toolchange
	time_scale = (
	2.0 # Multiply estimated move time to compensate for acceleration/other overhead
	)
	# Increase if preheating still starts too early

	#!/bin/sh
	cd /tmp
	wget https://www.cloudflare.com/ips-v4 -O ips-v4-$$.tmp
	wget https://www.cloudflare.com/ips-v6 -O ips-v6-$$.tmp

	for cfip in `cat ips-v4-$$.tmp`; do echo "sudo ufw allow from $cfip to any port 443 proto tcp comment 'Cloudflare ipv4'"; done
	for cfip in `cat ips-v6-$$.tmp`; do echo "sudo ufw allow from $cfip to any port 443 proto tcp comment 'Cloudflare ipv6'"; done

	import dearpygui.dearpygui as dpg

	# thing user last clicked
	global currentPick
	currentPick = None

	# thing mouse last hovered
	global currentSelection
	currentSelection = None
