Guys, i want to add a 12v led strip and maybe later on a fan, does anyone know a quick 12v source i can tap into without pulling the whole printer apart? or is it easier to just tap straight into the printers power supply?
regards

Tap into any of the yellow and black wires from the power supply. Be warned the stock supply is underrated so an LED strip may add too much of a load.
I thought of that. However I think I will go for plan B. I'm going to print a side window and glue some strip LED lighting 5v versions to it. Then I can run out a line to a USB male connector. It can then be plugged direct in to a USB hub and take the power from there. That way it isn't permanent and can be removed any time
I was going to just print this and drill a hole for the line out to USB . LED space would be tight but if I run them round the edge I could probably fit a small strip either side
I tapped into my 12v at first, it made my machine lag so I just replaced the power supply.
thanks for the info guys, i may look into 5v led's and tap into the existing led loom, @chrismetallica1 thats a great diagram and i cant wait to see the finished result !
@ horto89 I printed the housing today. Once I get all the fan parts LED and other bits I will let you know and do a post. I couldn't be bothered altering the original part as its only 1 wire out so I will just get my drill out and do that
May I ask what the goal of the fan is?
I used an external source for 12v, the davinci power supply is too shitty. I went with the ducted side fan design, but i havent actually used it as i have been using abs lately.
If you plan to use this for printing PLA it probably will not work. The issue is not with PLA layer cooling so much as it is cooling the throat of the extruder. A fan blowing across the print area in this fashion will not cool the throat enough and you will still get swelling and jams. You should look as Scobo's thread. He did a very easy mod by adding a few heatsinks and moving the existing fan slightly lower and is now able to print most filaments.
Of course layer cooling is important as well for PLA but this set up will still not accomplish that either. All you will do with this is keep the inside of the printer at room temp and make the entire print cooler then the last few layers laid down which will cause warping probably.
But since you have it planned this far go ahead and try it. I might be wrong.

To make it easy I just got one of these http://www.amazon.co.uk/gp/product/B00 … 1Q3IN4TG2S a switch and an adaptor to plug in the wall. Sorted. You really need a good draft to print something in PLA with lots of pointy bits quickly.

After all else failed (6 times) when trying to print a small pointy part I put a fan in the Da Vinci blowing across the bed and printer head. It worked. No curling. No lifting. No deforming. It worked great.

Searching the Scobo's thread without success. Could you add here a link to that mod?
