Assembly Stepper Motor Connection

[EdmondsLibrarian]

The documentation for putting together my second Makelangelo is fantastic. Model 2.5.2 (So glad we don’t use string any more! It feels like a “real” machine now.)

One step I’m confused about is the connecting of the stepper motors to the board. There are 4 “screw”s to attach wires on the board. The stepper motor has an awesome connector that I don’t want to cut. What kind of connector do I need to finish the connection?

I think this might be a connection I want. I will have to cut one end to attach to motor drivers board. Anyone use anything like this?

This was a poor choice.
The pin connector cut in half easily enough.
However this exposed the fact that the metal is shaped to fit inside the plastic, and definitely not to connect through to another. Any inventors out there? Seems like it shouldn’t be that hard to have a universal connector that is both male and female…

Anyone know an actual product made for this task?

These might work: http://www.dx.com/p/arduino-dupont-4-pin-male-to-female-extension-wire-cable-40cm-10-piece-pack-140523#.VtyRCNCmMso

Cut in half, strip the wires on the male end and screw them into the shield, then plug the steppers onto the male end.

This looks like an awesome option.
Wish I had seen it before I bought a set of breadboard jumper cables, which look like they are also going to work well. I will try to post a picture after I know it is working.

You could use ELEC-0058 1m extensions with ELEC-0049 male-male headers in between, then put electrical tape to hold it all together. There’s a small chance that the electrical connection won’t be awesome and you may lose steps, but only testing will tell. Nothing’s as good as a single direct wire.

That’s excellent advice. More patience and I might have followed it.
Will be testing soon. Here’s the pictures of the current set up in case anyone else finds themselves in a similar place.
