Easy 12V LED strip control on 24v supply

Neat. I still need to figure out a good way to mount lights on my Kossel Mini.

Thanks for taking the time to share, this could come in handy.

Hey_Allen

Thanks for the link to the regulator.

@JohnOCFII: On the Kossel Mini, depending on the size of extrusion and the size of LED strip, you might be able to slide the strip into the inside slot on the verticals.
I've tested this on my 2020 v-slot frame and found that the strip that I have will slide in from the ends, but won't insert from the side.

No problem I didn't want to go messing with transistors and other switching circuitry, and this seems to be an ideal solution. Up to 3A (though, I'd probably not trust it beyond 1.5A-2A), adjustable voltage, cheap, and easy to wire. Will also be wiring up one of these at 5v to power a Raspberry Pi to run a webcam.

Would it also be possible to get some 5 v rgb leds connect each colour to let's say heater 3-5 on the expansion header and gnd to gnd obiously and controll the colour via M42 commands? Would the heater pins supply enough amps?

Just to wire everything right. Can you explain where is EN - Duet Heater 3 pin on the expansion header?
Is it pin #8 on expansion connector?

Yup, pin #8 is correct.

You can also use pwm to dim the LEDs

Thanks. I've got 2020. Are you lighting from the lower part of the vertical 2020 – below the area where the carriage will run?

I'm planning to run most of the height of the verticals on mine, including where the carriages will move.
Since I'm using v-slot wheels on the sides and the ribbon is inserted inside the extrusion, it's below the surface and out of the way of the carriage.

Oh yeah! Great idea. I forgot about that.

I also used 12V strips on 24V system but I cut them in half and wired them in series. Then directly connected to Duet. Can't get simpler than that I think.
