@Oddity3D how do you turn off the toolhead light in code on your X1C?
I understand the GCode to toggle the toolhead LED is;
M960 S5 P0; Bambu Lab toolhead logo light off
M960 S5 P1; Bambu Lab toolhead logo light on
But how do you actually send this to the printer?
Very often either when I stop a print even before it starts to print or after finishing some prints the toolhead LED is left on only to be turned off following the next print job if I am lucky.
I would love a simple solution to be able to send GCode or something to turn the toolhead LED off.
In fact when it finished my last print yesterday the LED has been on ever since and will stay on until the completion of the next successful 3D print job.
Thanks for the reply @Oddity3D even if it wasn’t quite what I was hoping to hear!
If not on the fly is it possible there might be a way to just add an LED off GCode script onto the SD Card so I could access it from the printer and just print the ‘model’ so all it does is turn that damn toolhead LED off?
I have 2 X1C’s. The first one bought in July 2024 turns off the toolhead light in standby mode. The second one, bought in January 2025 keeps the toolhead lights on continuously. Would be great to turn this off, without having to turn off the printer, as I sleep near it, and it’s bright.
As a side note, the newer X1C has a less opaque smoked door glass (lets more light through). This might help to differenciate different batches of X1C’s.
I just received my X1C, the tool head light turns off at some point when it’s not printing. Not long after, either. Can’t be tied to the screen as it’s off when printing, at least I’d think it wasn’t tied to the screens timeout.
To the OP, I noticed the AMS 2 Pro lights are off after boot up, until a filament is loaded, or it’s printing, and then it’s only the light with the active filament.
I also set up my printer with the AMS in the bedroom. My AMS is placed on top of the printer and can only be properly accessed from the front and the left because I have very limited space. As a result, the power switch of the P1S, which is located at the bottom right/rear, is difficult to reach. In a completely dark room like a bedroom, the lights in general bother me, which means I have to fully power it off every time using the hard-to-reach power switch. It would be really great if all lights, including those of the AMS, could be controlled an switched on/off via App or the automatic standby.
