Photos or advice on electronics much appreciated

Hello everyone.

I this has been asked before, then I apologise. but otherwise I’ve a quick question on the electronics.

So I have a 1.4 and mega 2560 sandwiched together (I assume this is correct?), the pins under the stepper shorted (as per instructions) and the stepper drivers in place.

Do the two boards need separate 12v power supplies? I have the lead that fits into the 2560 but the instructions show 12v cables going to the green pins on the 1.4?

Even a photo of someone board would help leaps and bounds.



Just the green plug needs power. Have a look through these links and let me know if there are any more questions.
