Check the tread pls … Thanks 
Думаю вы заблуждаетесь, светодиоды используются для подсвета маркеров.
I am not mistaken .
It is called Fill Light originally created to capture better color data , it also help taking pictures of the calibration board while calibration where the pictures are taken . It’s specific color blue is used when scanning color data that absorbs mostly blue tones , without it scanning if the surfaces is much harder and sometimes just impossible .
Please write in English , this is English speaking forum . Thank you. !
Sorry, I forgot to turn off the translator. I have other data, the fill color is designed for greater visibility through the installed blue filter, including markers, in any case, this is how the red-illuminated laser works, I don’t think there is a difference other than the wavelength.
It is a simple blue LED light around the depth sensors , the main laser is blue and so are the DLP projector in the middle .
The RGB cam has a special blue filters that eliminate the blue tint while capturing the color data , the fill light helping to eliminate the absorption of blue light by specific colors .
That are my info from designer team of MetroY series
Anyway , let’s get back to the topic as the thread is not solved yet.
Extension it is then. Any chance we can get a replacement cable from the manufacturer?
I started looking for alternatives because I lost my cable.
okay, this is not the place, it’s strange that the developer answered that way, because I know for sure that the backlight is needed to stabilize the image and reduce noise, which in turn cannot but affect the markers. in general, the fill light is important not only for highlighting the texture. thus, it is important to ensure that the fill light turns on.
I consulted with the neural network and received this formulation: Blue fill illumination is used to stabilize the reflected signal in the operating spectrum, reduce speckle noise of the laser, improve SNR, and ensure reliable capture of both texture and positional markers through spectral filters.
Please contact customer@revopoint3d.com
And request the replacement cable , please let them know you have purchased the kit before but just lost the cable and you don’t need the full kit again .
As you already found out the cable itself needs the PD chip in it. I made myself an extension (guide here: USB PD Power Cable for the Revopoint MetroY Pro by PrintedForFun | Download free STL model | Printables.com), but it’s a bit like playing with fire since it will fry most other devices so take some precautions to prevent misuse.

Thanks Philip !
For those that do have the short mobile cable , you can use Thunderbolt 4 extension with that
I reached out to Revo as you recommended, already placed an order for the extension just to be ready if costumer service reply with a solution.
Now it’s time to wait. Hopefully soon.
I watched the @PrintedForFun video, lots of info there. Thanks to that I think I found a less DIY workaround to the 12v cable with this cable.
It is plan B just in case I can’t get a new OEM cable.

I would get one outputting only 12V without the option to swith voltages. One mistake and you fry the scanner with 20V

I understand your concern. That is what I picked one that requires a little tool to select the operating voltage.
Once it’s set to a specific voltage, it stays at that voltage until the key is used to change it.
Edit: Worth mentioning that using that cable or a similar one is only being considered as an alternative if I can’t procure a replacement for the OEM one.
Would one of these PD cables work?
Get better a Thunderbolt 3 or 4 cable , works best with Revopoint scanners.

What will you use it for?
If it is to power the scanner directly from the power bank, then no.
You could use it as an extension with a female-female usb-c adapter, but at that point it would be as good as the male-female extension.

Hi Luis,
I have that cable , it was good to charge my MIRACO and that is.
After watching @PrintedForFun ‘s video, I now have my doubts that the USB-C PD cable I provided the link to will work. Phillip is pretty clear in his video that the MetroY scanner does not use the PD voltage/current negotiation protocol with the power bank. I think the dedicated 12V cable that Phillip made is the probably the only way to go to power the MetroY from a PD capable power bank.
The easiest/safest way to accomplish what you want is with a usb-c extension cord connected to the factory included cable.
With this combo, the OEM cable will be in charge of determining the amount of power it pulls from the Power bank.
The only thing I can’t guarantee is that it would work with an extension that is longer than 30cm.
I will try a longer extension once I replace the OEM cable I lost and will update this thread with whatever info I discover
