Make your 3D printer tons cooler and more functional by adding LEDs the printer controls itself! This method will work for almost any 3D printer and you don't need to do any complex electrical work or mess with the firmware. This is the complete guide from selecting which LEDs to use, over control options, to configuring things to be automatically controlled!
🛒 Here are all the materials you'll need!

Thanks Tom for the tech tips! If I can be honest, this is the kind of technical stuff you used to put out more and why I started following you. I'm less interested in reviews and more interested in technical data. Not that I don't like your reviews, but as a geek,I love being able to dive into the gear more. Today I had my y-axis channel on my ramps/arduino board die from a cheap Aliexpress driver, and I dug into the code and figured out how to remap my y stepper signals to my unused extruder driver so now I have a working board again that I don't have to toss out. I'd love to see more of that deeper diving material from you, you are pretty sharp and know a lot about this stuff. Thanks for the great videos, I watch everything you post!

Great video! One thing that I especially like is your DIY driver board for driving RGB LEDs (at video position 5:53). As a DIYer, I would love to see a follow-up video or live-stream where you give details of the circuit design, discuss part selection, and then build a copy of the board from parts. Thanks again for all the great content.

I completely forgot about all the direct pin control GCode commands and a few of the others. Thank you! I've connected some status LEDs(In a little 'tower' atop the printer) to hot end fan, stepper enable and a few other spots so the lights show the physical status of the machine even if somthing goes wrong with the machine(Like an overtemp, mistake in the gcode or other problem). But I do like this idea for the overall lighting control.

Tom, fast forward to 2022, I'm still using the Prusa clone I've built following your series, and in the spirit of RepRap, printed the parts for another one with 300x200 bed (and whole bunch of other mods), on 12mm ply reinforced frame and the things haven't stopped printing!! Now, I've decided to add LEDs, just for the fun of it, and this helps a lot.

Extremely helpful video! I have some spare LED strip and was considering installing some on my LulzBot Mini as I'm fed up with not being able to see what's going on! Although the PSU is 24v and the LED strip I have requires 12v I was going to connect two pieces of strip in series so they both have 12v from the PSU. I was going to use a small switch on the front of the printer controller case but having seen this I'm considering the alternatives, although I may still include the switch for isolation purposes. Looks like my weekend is going to be illuminating!

If you want some additional control over your RGB or RGBW LEDs or LED strips, there's a whole new set of options in Marlin 1.1 supporting a few different kinds of LEDs. With `PRINTER_EVENT_LEDS` enabled, during heating the color will gradually change from blue to red before returning to white, and on SD print completion the LED goes green for a second, then turns off. Of course, you can use "M150 R U B W" to set the RGBW components from your G-code, rather than relying on "M42." Enjoy!

@ScottLahteine 7 жыл бұрын

Note that I've also added a command (M43) to report what all the pins on your board are assigned to, and whether they can do PWM. It makes finding available pins for your LEDs and other add-ons much, much easier! This command is enabled with the `PINS_DEBUGGING` option, and should be disabled when not needed.

Very interesting video. I tried using the setup as shown on the reprap forum in regards to the FF module, but was not able to get it to work. This module is suppose to handle the lighting and also apply sounds to the actions of the start and end codes. Not sure why it didn't work, but it would be a very cool thing to have for demonstration 3D printers that are designed to encourage new people to 3D printing.

Even if one free pin could possibly connect neopixels. All exists in Marlin just need some board info on pin possibilities (and pin redirecting if needed). Again, excellent videos.

@Howeson1 5 жыл бұрын

Rather than using a buck converter to step down from 24v to 12v would it not be easier to cut 2 led strips and wire them in series such that the voltage is split across them and they get 12v each?

@wi_zeus6798 5 жыл бұрын

Yes, this would work but then again if there should be a difference in forward voltages, the LEDs might be strained quite differently

@JPWestmas 7 жыл бұрын

Points Taken. I think setup in general is always a huge time endeavor and it tends to be more objective and plain speak. I think I'd like to see more videos in general about hot to get certain kinds of complex designs to print whether they be purely mechanical or aesthetic effects. Torture tests can only tell us so much I think.

It would be cool to use the gcode to mark when a overhang is going to start and then tilt the printer so that supports would not be needed. The Dolly and Prusa MK2 are stiff enough so that you could tilt the printer by 30 degrees which would cut out a ton of supports material for simple parts.

Great video and information. I have started working this mod and noticed that Cura will add the M109/M190 commands as the very first 2 lines in the final gcode file. So no matter what I have in the Start Gcode section, there will always be M190 and M109 as the first two lines. So unless I do a post edit, I can't turn on LED's until the bed and extruder are at temperature. Any thoughts on how to fix this?
