      Hello I have a 24v LED strip that I would like to connect 6HC that is running at 24v. LEDs are PWM dimmable so I think connecting to a fan output as 2 pin connection makes sense.

      If I use the entire 16ft roll the energy required is roughly 40 watts, which should be well below the current limit for the fan outputs on the 6HC.

      The dimmable driver that could be ordered along with the LED strip has a PWM frequency of 2000Hz.

      I'm thinking I just setup a new fan in config for whichever fan output I use, set Q value to 2000, and then adjust fan values to control lighting.

      Is there anything I'm missing here? Any considerations for wiring or otherwise?

      Thanks!

        That sounds OK to me.
        I glued my LED strip of about 30cm into an aluminum L profile and mounted it on the printer's boom, the L profile serves as a heat sink and is also a glare shield so that only the print bed is illuminated from above and not the whole area behind the printer .

        I also connected the LED strip to a fan connector.
        However, without a dimmer module.
        My command line in config.g looks like this

        M950 F2 C"fan2" Q500
        M106 P2 B0.0 C"Beleuchtung" X51
        

        I limited the brightness to 20% power with the X51 parameter (0 - 255 = 0% - 100%).
        In the DWC I have a slider labeled "Beleuchtung" (Lighting) that I can use to dim the brightness without a dimmer module.
        Possibly the dimmer-module of your LED strip might not be necessary, but since I don't know your LED strip I can't say 100% if this is the case.

        Das klingt für mich ganz OK.
        Ich habe mein LED Streifen von etwa 30cm in ein Aluminium L Profil geklebt und diesen am Galgen des Druckers montiert, das L Profil dient als Kühlkörper und ist gleichzeitig als Blendschutz so das nur das Druckbett von oben beleuchtet wird und nicht der ganze Bereich hinter dem Drucker.

        Ich habe den LED Streifen auch an einen Lüfter Anschluss angeschlossen.
        Allerdings ohne ein Dimmer-Modul.
        Meine Befehlszeile in der config.g sieht wie folgt aus

        M950 F2 C"fan2" Q500
        M106 P2 B0.0 C"Beleuchtung" X51
        

        Die Helligkeit habe ich mit dem X51 Parameter auf 20% Leistung begrenzt (0 - 255 = 0% - 100%).
        Im DWC habe ich einen Schieberegler mit der Bezeichnung "Beleuchtung" an dem ich die Helligkeit dimmen kann, ohne ein Dimmer-Modul.
        Eventuell könnte das Dimmer-Modul Deines LED Streifens nicht notwendig sein, aber da ich Dein LED Streifen nicht kenne kann ich es nicht zu 100% sagen ob dem so ist.

          Thank you for the response, I will try setting it up this weekend. Mounting to the gantry sounds like a great solution for illuminating the print bed, unfortunately I am using ExoSlides which would be obstructed by the LEDs.

          I will have to get creative for a good mounting solution. Mounting to the extrusions would be good for heat sink but I dont have any good angles for illuminating the bed with the available locations on the frame.

            I would definitely make sure to stick the LED-Strip only on metal.
            Firstly, the heat is dissipated better and it is safer than sticking the LED-Strip to plastic, wood or other combustible surfaces, for example, because LED-Strips "can" get very hot.
            And you don't necessarily have to push your luck. 😉

            Ich würde auf jeden Fall darauf achten den LED-Streifen nur auf Metall zu kleben.
            Erstens wird so besser die Wärme abgeleitet und es ist sicherer als den LED-Streifen zB auf Kunststoff, Holz oder andere brennbare Untergründe zu kleben, denn LED-Streifen "können" sehr heiß werden.
            Und man muss das Glück ja nicht unbedingt herausfordern. 😉
