is there guide or video to use RAMPS using CNC Shield?
i'm still don't understand how to setup the marlin using this http://reprap.org/wiki/Adding_more_extruders
thanks

I have the feeling that I did answer this question somewhere, but can't find it. ;-)
No I can't help you with marlin, I used repetier, but perhaps you can get some ideas from notes I made at the time.

The connections they gave on that page didn't work with me or are plainly wrong, I don't know.
Eventually I used directions from http://www.reprap.org/wiki/Repetier_Color_Mixing:

In the file "pins.h", at the "ramps1.3" (to be used for the 1.4 too):
"#define ORIG_E2_STEP_PIN 64"
"#define ORIG_E2_DIR_PIN 59"
"#define ORIG_E2_ENABLE_PIN 44"
and:
"#define E2_PINS ORIG_E2_STEP_PIN,ORIG_E2_DIR_PIN,ORIG_E2_ENABLE_PIN,"
(Don't use the quotes-characters).

I didn't change anything in Configuration.h for the shield.
The wires from the shield to the Ramps should go to the AUX2, not the AUX1 connector and don't forget the 12V connection.

Hope you can do anything with it. I don't use the shield now (though it worked ok), so that's all I can offer you.

You know, a Rumba board (http://reprap.org/wiki/Rumba) would solve the stepper channel issue with using the Diamond hot end.

I can get several RAMPS + Arduino + CNC shield kits for the price of Rumba. What is that issue you are talking about?

Sure. But would that fit in the original enclosure?
Anyway, I didn't have an issue with the stepper channel, because I chose the CNC-shield , could keep the Ramps and that was that. ;-)
But I am sure the Rumba provides a good solution for the extra channel, especially when you start from scratch.
Elegance for a bit more money.

Thank you, Fractie.
Concerning the keeping it closed, I saw a comment about that with the original box, oh I see now it was you ;-).
So I wanted to make the pins a bit bigger. Your post now made me think again and I realized that in all the to-ing and fro-ing in FreeCAD I only did it with the hinge pins, and lost the other ones (that's to say not the original pins, but the bigger ones).
Which explains why it is still not ideal, but in practise it stays closed if, and only if, I see to it that all cables stay out of the way of the cover.

I must confess that I still am a beginner with FreeCAD (linux), which probably explains why I had so much practical problems with the Boolean operations. It seemed a bit of a lottery when it would succeed and when not, especially in this project, so I am a little hesitant to dive in again and add the other bigger pins, now I have a "working" box.

And now I am at it, I'll add a warning to the description: because of those bigger hinge pins you probably will have to put a bit more effort in joining the two parts. With the help of a scrowdriver and a little twisting I could do it repeatedly without any problem.

I am not sure what you mean with the cable management. I shorten or lengthen cables as soon as I see the need for it.

Hey PrintingSome, thanks for your reply! I'm also starting to get into OpenSCAD, so maybe I can get to it myself. Currently, Its zip tied shut. elegant? no lol, but it stays shut :D

By cable management, I mean making the channels on the side deeper so that more cables can fit. I have the issue you described, where the cables aren't all properly in and it doesn't shut all the way. I thought deeper channels for the cables would mean it would have less to contend with when closing it.

I did not see the need for it. When using the diamond hot end and the CNC-shield the extra cables come in from above anyway, in my case. And that worked too, altough indeed it got crowded in the upper right corner.
As it is I don't need zipping, it just clicks in its place and stays there.
But of course, the deeper the better, you are right in that.
Those channels are some of the great things in the original design, worth excavating, i.e. lowering, some more. ;-)
Although, when doing that, you need to redesign the CNC-shield mount too. You cannot lower that, lest you get into trouble with the ramps underneath.

This is great! one of the major problems I had with the original Dasaki Ramps 1.4 Enclosure was that I could never get it to close... have you considered lengthening the cable management?
