LED barre: how to make a growing left to right LED while print completes?
Hi!
As said on title, does anyone know how to make the LED growing from left to right accordingly to the completion of the print?
That should be very nice to quickly see how the print is going!
Thanks a lot!

Or how about a red light sweeping left to right like KITT (Knight Rider) or a Cylon eye (Battlestar Galactica), depending on which classic show you grew up with, haha!

Haha, if there is a way to modify the sequence I guess we could make anything we want, but we have to know hoow to change it first!

None of this will be possible with the original LED strip. It is a regular analog RGB strip, where all the diodes are controlled by the same signal (PWM).

I don't think that is correct. It's a strip of WS2812 LEDs, which are individually addressable via a daisy-chained serial data link.
But to my knowledge there are no provisions in the firmware for controlling them individually. Prusa's take is that you already get a "vertical progress bar" as the print bed moves down over time.

Sorry, I was wrong there. Was really sure I had seen them labeled as WS2812 in the schematic, but they are not. There are separate PWM lines for R/G/B/W intensity, which will go to all LEDs in parallel.

50 individually controlled points.
And the best thing: As long as you keep the LEDs flashing that, VFAs no longer matter at all! 👍 😉
