I've noticed a few people have LED's on there CNC to show what it happening on the CNC. there are Tower lights available but seem to be very simple.

I've created a LUA script which pairs with an arduino. 3 outputs from your BOB are needed so it's not for everyone if you don't have them.
I used an arduino mini pro for mine. Just about any arduino will work though. maybe not ATTINY's though. 3 inputs and one output. Arduino
bit bangs the addressable RGB LED strip. I used a 1 meter (39") long strip with 144 LED's in it. Still a couple of little niggles to investigate, but it's working.
script's and code are available on github at
https://github.com/cdedwards/Tower-Script/tree/main

This will eventually work on MachPro as well. (a little problem where it's giving me an error about an ='s sign)
