Directly connecting a 24V LED strip

Hi, is it possible to directly connect a 24V LED strip to the Prusa Mini? Where would I do that?

Many thanks

RE: Directly connecting a 24V LED strip

Hi.

Well yes it's possible with some tinkering, but I am not sure if I would recommend it to someone with no electronis experience.

You can grab the +24V at the spade connectors that go to/from the powerswitch (here called powerswitch pins). A suitable GND connection is not that easily accessible, which is the first problem. Another problem would be the maximum available power. When all heating elements are powering up, the power supply does not have much headroom, which wouldn't make it advisable to run an LED strip at the same time. This would make some kind of remote control (raspberry?) or additional manual switch necessary.

The maximum power consumption of the LED strip would be interesting to know.

The Prusa Mini power supply delivers only 160 Watt. Of this, the printer bed heating requires up to 115 watts and the nozzle heating up to 40 watts. There is not much left for the rest. If you connect anything else to the power supply, it can cause malfunctions, depending on how much power your LEDs draw.

Statt zu klagen, dass wir nicht alles haben, was wir wollen, sollten wir lieber dankbar sein, dass wir nicht alles bekommen, was wir verdienen.

Thanks, I'll look for other ways to power the LED strip in my enclosure.
