Okay, so someone gave me an old 3D printer build kit - there's no instructions, no disk, I'm not even certain which printer it is (I THINK it might be an old version iPrusa, not sure).

I've managed to figure out how to build it (the frame at least) by looking at a lot of different videos but I'm not sure what to do in regard to connecting the wiring, particularly for the Z motors. It's my first attempt at a 3D printer so any advice or help would be hugely appreciated. I've added a photo of the board that I'm wiring to. I don't know if it's right thus far - I think I need to wire the two z motors together, black to green and red to blue then use the remaining wires???

Not a clue, please help!

That is an old melzi controller [reprap.org]

For Z the steppers are simply wired in parallel.

Thank you, you absolute star!

Fingers-crossed I can get it working without setting it alight on accident. If not, I think I'll just drink and enjoy the warmth smiling smiley
