Let there be light

Hi Guys

Short question. Is there a detailed layout of the printer controller board available?
I was thinking to add a light under the extruder arm so I can see the prints better and dont have to
leave the lights of the room on permanantly.

Therefore I need a 12V power source for 60mA. So I was thinking is there maybe a possiblity to connect it onto the
controller board so I dont have to add a need power supply. Connecting it directly to the power supply also doesnt work
since this is 15V. Sure a LM7812 and som conductors would do the trick but I thought maybe theres a other way.

Best regards,
Christian

Hi Christian,

I have 3 snippets of the led-stripes (the kind you can divide every 3 leds) under the extruder, directly powerded via the power supply.
They are also rated for 12V but as today no problems with the 15V.
To be on the safe side you can use a additional resistor serial to the leds to lower the current a bit (think about 100 - 150 Ohm would be fine).

Regards Bernd

I also have a 12V LED mounted and I simply inserted a 3.3V zener diode to connect directly to the 15V supply.

(At 60mA, 50 Ohm would be correct)

Hi
I lighted up my k8200 with two Jansjö from Ikea. Just clamped to the moving z-arm. Quick and easy, could remove without tools.

We will release a dedicated led light ring by the end of the year.
9 high-intensity, wide angle leds will light the area around the extruder.
It will not require assembly and it will plug right into the female DC connector of the controller board.

Today i had conected my LED Lights.
I had used this parts from Reichelt.de :
http://www.reichelt.de/Sockel-G4-GU4/LED-G4-10SMD-WWS/3/index.html?&ACTION=3&LA=446&ARTICLE=85623&GROUPID=3951&artnr=LED+G4+10SMD+WWS

The 15V power is no problem for the LED because it is a litle switching unit on the LED-PCB for regulating.
Tested from 10-20V and no div. in the ligt intens or the Power input (1W)

The light will used 2 printed parts.
The holder for the G4 socket and the LED PCB
The clp for mountig to the frame




With thee LED Hölder and the Clip it is posible to mount it quick to the frame

So i can light out for the octoprint webcam and can see the gears of the extruder rotating

In the moment i use 2 lights:

  1. Behind the webcam (on the left side)
  2. Behind the extruder

More pictures and the STL file i had uploadet by:

i designed also a light for my velleman K8200.

You can look at my design on thingiverse.com/thing:155262.

(little question: how you can insert pictures here? )

hello Arnevdm,
nice desing.

You can not upload pictures in this forum.
It is only posible to insert a link to the picture an then select the link and klick on the button “Img”

look at the posted link of vel417 (velleman.eu/images/tmp/K8202.jpg)
they will use wide angel LEDs, so the full light intens will shine in the middle under the nozzle
your LEDs have a smal focus.
Did you use a resitor for the LEDs
