Enable 12v-pin on board (MKS robinv2.3) April 08, 2025 06:05AM |

Hello forum community,
I want to add an led-strips for my printer by using the 12v-pin ( in photo) on board.
But it seems it didn’t work. Do I need to do something, for example, change some settings in the configuration for enabling the pins?
Thanks for your time in advance!

... is the drawn current supported? ... and what's with the polarity or reference level?

the 12/24v pin is directly connected to the power supply (via fuse f2) . there is no settings for it. It is always on if the power supply is on.
They are labeled 12/24v as they are the same voltage you supply the board power pins with, ie 12v or 24v
what sort of led strips?
neopixels or ws2812 wont work as those need a data pin.
also most leds need somthing to limit the current, or they just burn out

... look into the data sheet of the LED stripe, which current it uses ... then check, what max. current is supported by the output ...

... hmmm ... some of my (12V) LED-stripes have already internal current regulation, so simply connecting to a 12V PS would be enough.
Others (mostly RGB-types) have either 4 pins for the "colors" and GND or 2 pins for the current and one for the selection or serial data.
Do you have a link to your specific type or the data sheet?

Thanks a lot for so much help! I think i should try it again later.
Ich bought this led-strip (originally for bambu lab a1):

It looks to have inbuilt resistors.
so it should work by simply plugging it into 24v and turning the switch on
Note. It has polarity. It will only work if plugged in the correct way
