LED Ring - Laser Position Indicator

[@fetchitnowuk]

Officially just had a nerdgasm at work. Will be making one of these when I get the chance. Pure genius.

[@possibility.of.miracles]

It’s a very simple, but so useful idea!

[@rcx575]

Why is this not the standard way of doing things? The head mounted position lasers get in the way, require chain to route power to them, don't stay aligned as you change height of table. This is so much better. I'm just going to use flat acrylic though.

[@GarageCrafter]

Genius. Pure genius.

[@andrewkline]

Clever idea, I like it.

[@bgaworkshop7209]

Very good idea and informative, I think this can be used to do the laser head alignment also. Thank you very much.

[@FrankGraffagnino]

this is fantastic! thanks for sharing this.

[@katchupoy01]

ha ha ha. very simple solution. pure genius. I like it....

[@douglarue8485]

Fantastic and one of the easiest and useful addons for the K40. It will be my first addon but as my second is going to be air assist and I trust your choices, where did you get the design for the nozzle you are using?

[@ScorchWorks]

The nozzle is my own design. I just uploaded it to YouMagine. There isn't anything really special about it. www.youmagine.com/designs/k40-air-assist-nozzle

[@DoRu42]

Thanks, it was different than what I saw on Thingiverse so thought there was something special about it. VERY nice you did it in OpenSCAD. I was surprised to see there was no inner chamber and the laser head was exposed to the pressure. I figure it is since the laser head makes the blocking surface for the air and I figured it was a hallow funnel with the angled mirror. Thanks again. I'm making space today in the garage for the laser cutter(still in the box and it's killing me! ).

[@nraynaud]

seeing your video just gave me an idea: could you put a red line laser on the side of the hole? one vertical line on top of the hole and one horizontal on the side of the hole. It feels like you could get a fine cross from that, still without the inconvenience of having something actually in the path of the beam.

[@ScorchWorks]

I am not sure how bright the lines would be where the lines cross. Could be cool if it works. Let me know how it works out.

[@maxdgac]

Wow, very clever and nice solution !! Congrats !!!

[@Dfrantz87]

Bad ass idea brother. Very nice.

[@joeyscollinsful]

Great stuff Man! Thank you

[@neatpleats11]

That was a very smart idea. One of my biggest pet peeves is that the red led that comes with the unit is not accurate. If you move the table up or down, it changes the position. I have a bunch of Harbor Freight dead flashlights that have 8 led's on the outside and one on the inside. I am going to give this a try. I don't think it is necessary to 3D print the bracket when you have a laser that can make the parts much easier. Also, would it be a good idea to mount it directly to the laser at the exit of the laser tube? I think making a bracket to fit there would be pretty easy.

[@ScorchWorks]

Yes, there are many ways to make this concept work. (Of coarse mine is the best...just kidding)

[@hopelessnerd6677]

I'm late to the party, but this is bloody brilliant! What about red LEDs'?

[@ScorchWorks]

The original video, by Peter Jensen, that I reference in the description used red LEDs.

[@juhaszpeter4796]

Would this idea work with two laser lines? With the one in the levelers.

[@eDAD-fr]

really cool thank you

[@haquedmd]

Brilliant! Love the idea! Can you provide a link for the lights and perhaps a picture or video showing the wiring downstream?

[@ScorchWorks]

The LEDs came from a "Guidesman 210-1004 14 LED" flashlight. (I am pretty sure my mother in-law got if free after rebate at a hardware store.) The magnet was salvaged from an old microwave oven. The power supply was a 5V DC power supply from a flip style cell phone. I wired a 180 Ohm resistor in series with the LEDs. This was completely made with things I had in my parts bins. The intent was to show the concept not the best way to make it.

[@haquedmd]

Scorch Works: you are the man!!!

[@widi1705]

very good

[@manuelvillalpando6665]

Do you happen to know if there is a shop that manufactures these types of lights? I don't have all the tools and components that you have on the video to make the LED light, or the expertise in electronics to solder everything together correctly. I would hate to invest time and energy into making the light and then end up frying something. Marvelous product to produce a quick center on the K40! Thanks!

[@ScorchWorks]

I am not aware of anyone selling something like this.

[@manuelvillalpando6665]

@@ScorchWorks that’s too bad. If you ever make any for sale, keep me posted. I’d be willing to buy. Thanks again!

[@cicciofranco405]

Hi Frank, I'm Francesco from Palermo congratulations for the beautiful video of the k3020 LEDs. If you come to Palermo, I invite you. :-))

[@mineralhillsworkshop5275]

Thank you!

[@alexeysharonov7765]

Awesome

[@steveohkingman]

good job... clever..

[@RochdaleBlue]

Hi great idea what size of magnet are you using and where did you get it.

[@ScorchWorks]

+Anthony Atkinson The magnet came out of a microwave oven. This was made with stuff I had lying around so it might be difficult to reproduce exactly but the basic idea could be be reproduced in many ways.

[@karllaun2427]

Nice! Maybe a few smaller neodymium magnets instead of the one big one...

[@ScorchWorks]

I am sure a couple of neodymium magnets would work and be more compact. The magnet I used was salvaged from an old microwave oven. I managed to make the whole thing from items I had lying around.

[@karllaun2427]

Thanks so much for the inspiration. I made my own version and it’s working great so far!

[@andrewgarcia5458]

Karl Laun hey how did you make yours ? I don’t have a 3 D printer any tips ?

[@brianfoster1504]

The circle got smaller, but it was harder to see because part of the arc of the LEDs was partially obscured by the air assist nozzle from the way it looks.

[@jameshilferty5403]

Stop being so smart!!!
