I’m looking to have the Chamber LED on my U1 turn ON when the machine turns on.
Is there an option that I’m missing?

I thought it did… Now I’m not sure. Well, I can check in 7h and 30m after this print 
There’s no option for this, no.
You could at a line of start gcode that would always activate it when a print starts. And it spaghetti detection or time lapse are enabled, these will also turn it on.
But nothing for when it turns on, no.
It makes me laugh though. Some people want it on all the time (I do too), others are asking how to always turn it off. Some only want it on at some times but then turn it back off at others…
Guess just more options would be nice. It’s just funny to me how a little light gets all the attention.

I have two LEDs in my Enclosure that I turn on just to admire the beauty within… Regardless of printing anything or not
Soon, I will also add my UV LEDs back into the enclosure because it’s been too long since I last printed GitD

I like having the option, its very easy to turn it on or off.

I know … like After you flip the mains, other than looking at the screen, how do you know it’s on? There’s no fan, there’s no light other than the screen that’s easy to miss.
I guess I’m not in the practice of leaving machinery powered on when I’m not using it, which is another issue. Regardless, I still feel like the LED turning on would be a great indicator that the machine has been powered on.

I have my screen set to always on, so I guess I hadn’t thought of the status part of it.

So, I closed the door behind me with the lights off.
There are status lights on the tops of the print heads, and on the auto feed units, this is kind of what I was looking for, but.. still, would be nice for the machine to turn on and say “Hello! I’m operational! Here’s my chamber so you can see if something is in me!”
I wonder if this could be sent as a ticket item for a future update?

I get ya!
For me, I flip the switch and know it’s on… With my current setup, I usually turn on the LEDs in my enclosure before flipping the switch so the “tiny” LEDs in the machine don’t really do much for me.
Maybe there’s something like what BIQU does in their Panda line. I got their LED strip for the P1S and its way better overall for light; however, I don’t think that helps with the auto-on request.
For at least the operational part, wouldn’t setting the display always on at least solve that part?

I thought it came on for detection purposes? I accidentally hit the button once and it told me the light is needed so I assumed it was always on during prints.
It gets enabled if spaghetti detection is active, and at the start of prints where a timelapse is requested. But no setting to turn it on all the time.

This was the message, thanks!
YES，You can file a support ticket—U1 is about to enter a new round of Feature optimization, so now’s the perfect time to get your feedback in.

What I prefer is for the light to come on when the printer is powered on, then turn off when the print job is finished. The later can be set in the end gcode.

Ticket submitted with other requests I had from my other post.

I think we could consider using the reserved top-cover cooling-fan header on the U1 to control LEDs: set the filter fan to turn on in the slicer and the exhaust fan to turn off when the print stops.
So many suggestions. I hope any will be only added as options with toggles.
I’m satisfied turning on my LED then not having it turned off by anything. Lighting by my printer is not great. “LED on at startup,” for me, would be nice.
Honestly, other than the LED thing, I’m not asking for anything more than what’s offered using standalone Orca with Mainsail or Fluidd on the Device Screen.
I have this line in the startup G-code in OrcaSlicer, to turn on the LED when printing.
SET_LED LED=cavity_led WHITE=1
And in the end G-code, you just need to set the value to 0 to turn off the LED when finished.
