RAMPS + Arduino set-up plan Question for K800

Hello everyone. I got, and building a Kossel 800. (you can see the project over here, it is a mess. Once the machine printing, I will make a proper built/review of the machine)

But meanwhile, I am stuck at the RAMPS 1.4 and ARDUINO 2560 R3 connections. I am good at building stuff, 3D modeling, but electronics confuses me. BUT I still want to learn (and I am learning), but there are so many informations out there, and no one are really, truly, clear.

So I decided to make a plan of the Ramps and Arduino, the connections and photo reference. It is allowing me get it right without making something explode ... so far.

But I need the help of you guy's to get it right. once the plan is right, I will post it publicly so that, other's like me, that are confused, can have a clear idea of what is happening.

With all the help, and info I can add, will help me and other's. If you re-post this image with corrections (even if it is messy) I will put the correction on the Original, until I get it right ^_<

Do note this is for a modified Kossel Mini, the K800, with no heated bed and with a LCD screen. But I think this will work many others =)

There it is:

Hy J.A.C.

i have similar Problems like you.
I already have a Prusa i3 and it's working very well...
Now i decided to build myself a Rostock mini.
Why a Rostock mini?
Because of the low-cost building!
But there are NO step by step guides for installing the electronics and adjusting a Delta-Printer!

WHY?

Is it so frustrading to build one, that nobody whants to write down a useful How-to?

If someone have one please let me know!

There are at least two good guides on the web for building the Mini Kossel, written by kit manufacturers, for example this one [www.think3dprint3d.com] (go to the Documentation tab).

Hello,

Why that soldering on the underside of the barrel on the Arduino?

If you want to power the Arduino from the 12V you might as well use the build in feature in RAMPS.

See: [reprap.org]

And look at section:

Quote
[b]D1, D2 - Diodes[/b]

These must be placed in the proper orientation. The band on the diode must be turned the same way as the mark on the board.

Definitely solder D2 in. D2, F1, and F2 are shown installed here.

D1 should only be installed if the 5A rail is powered by 12V. It can be omitted and the Arduino will be powered from USB. You will want D1 installed if you add components to print without a PC. To reiterate, D1 MUST be omitted if you are powering the 5A rail by more than 12V, or the power is not absolutely clean, otherwise you may damage your ramps.

- Maybe you gotten your 12V power supply with the barrel plug. In that case you can do like you have done now and connect it to the Arduino and then soldering two small power jumpers on the underside of the Arduino. But it is not a "normal" solution and nor is it very neat in my opinion.

If you want to keep the barrel plug then you can buy a much more elegant solution that looks like this:

Then put 2 wires from that to the RAMPS.

And last you can just cut the barrel off and remove the insulation from the + and - and install these on the RAMPS.

Finally - I saw your reply regarding the Hotend - Looks like all is good and all the parts are looking good.
