@niocio01 unfortunately, Neopixel strings don't support setting just some colours. So you need to send the commands for all the LEDs that you want to change. You can either write a macro that computes and writes the correct colours for all 4 tools and call that every time the status of a tool changes, or you could use global variables to record the correct colour for each tool so that you don't need to recompute it each time.

@hlwerschner
Not much I'm afraid. I wanted to engrave some acrylic strips and animate them with NeoPixels. But i got so distracted by commissioning and upgrading the new Co2 laser, that I almost forgot, why I bought it 😉
In the meantime, I stumbled across a four color LED strip, which looks quite nice, too.
Now I'm trying to figure out, if designing a 4-fold NeoPixel LED strip would be possible. So I'm looking into the smallest possible footprint of programable LEDs.

I should mention, that this isn't my work. I found it on a discord channel about the K40-laser from the member @raineroe

@knutselsmurf there is no easy fix, because you need two separate UARTs to drive the PanelDue and the Neopixel board, and the only user-accessible UART on Duet WiFi is the one connected to the PanelDue port.
