Need a bit of help with the X & Y stepper wiring, I have wired them up as per the serial diagram on this site, but as expected they both turn the same direction therefore, obviously as they are opposite each other they both also need to turn in opposite directions, does anybody have an updated wiring diagram showing the correct wiring combination. Thank you in advance
Flip one plug over.
What do you mean flip 1 plug over? There is only a single plug which you join the 2 steppers to (Serial)

The plug from the far stepper to the harness, flip it over.

I’m not using the harness, I’m wiring manually, as its stands as per the diagram
Stepper A
Black (straight through)
Blue (straight through)
Stepper B
Red (straight through)
Green (straight through)
Joins
Green (A) - Black (B)
Red (A) - Blue (B)
My question is and what would the colour arrangement be to reverse a single motor
I am not sure what that means. Reverse a single coil on one stepper…or reverse them both.
I have a wiring page.
As per the attached photo from the wiring section, could somebody just explain to me which wires (colours) I would need to alter in order to get them running in opposite rotation.
Thanks
The simplest way to “flip one over” would be to take the red & blue wires (in the picture) on the right stepper and switch them with the green & black wires (also on the right stepper.) Based on your connections, it looks like you would take the stepper A red and green and switch them with stepper A black and blue.

Stepper wire colors don’t mean anything other than to help us differentiate them. There’s no code or standard to what color belongs to what pair. They could even change order from the same manufacturer. Like Ryan said, if one is running backwards, just flip the connector for that stepper over.
Hi, I understand the wire colours are irrelevant and just helpful for indication, I must be missing something but after re-wiring the steppers now seem to attempt to move but don’t. almost as if they are trying to move both ways at once.
I don’t have a connector to flip as these wires are going into a serial single connector which goes straight into the X or Y on the board, these are bare wires that I am currently just twisting together until I get it right.
If somebody could maybe update or draw a quick diagram based on the diagram I attached using the same colour coding I think that will finally shut me up from asking any more questions? 
Two thoughts:
- You have a connection issue where one of your connections is loose when you remade them.
- Check that you have the pairs identified correctly. To do this, I hold two leads together and then try to rotate the shaft. If the shaft is difficult to rotate, then the two leads form a pair. If the shaft rotates easily, then the two leads aren't part of a pair and I exchange one of the leads for one of the remaining leads and try again. One of the pairs will be the equivalent of the red & blue in the diagram while the other pair will be the green & black.

We are using 1, 3, 4, 6 on the nema 17 stepper as in the bipolar drive series connection. Note that 1,3 and 4,6 are paired. When you reverse a connection you are using 4,6 and 1,3 instead. 1,3 and 3,1 are the same thing…

Perfect, thankyou all working now
I see you solved this, and I was having the same issue grasping and was asking several friends of mine who kept giving me very complicated answers. Finally someone sent me this drawing and it all made perfect sense. Just in case anyone else is as slow as I am sometimes.

That’s the parallel wiring. Series wiring looks a little different. See the wiring page for more information.

BT, Apologies for the delayed response... lucky enough to have spent the last several weeks in a sling after rotator cuff surgery which makes even replying to mails take much longer.Thanks… that to is a very clear description for series. But, I have to ask, what is the difference? Each of my pairs appear to be running the correct direction. Is there a reason I should use series rather than parallel? Before I bundle, tighten and strap everything down?
Also, while I have your ear, can I ask, do you know of anywhere on the site that details how to properly (or most efficiently) wire up your tool head?i.e, my Dewalt dw660? I do understand it can be controlled by hooking it to my ramps board, but i’ve Not done this before with just a retail piece of hardware and don’t know if i’m Supposed to cut off the plug and wire it down to pins or what. I think if I knew what the expectation of the physical installation was, I can handle the code to turn it on/off, adjust speed, etc… It would be nice if there were a page covering this…might be, but I haven’t seen it yet and thought I had seen most every instruction on the site.
Again, I Appreciate the diagram and have added it to my library!

There’s a long thread on PID speed control and Ryan has a kit for sale in the shop. Other than that, others have used a wifi remote controlled switch for the router/spindle.
I modified the XY stepper mount STL that lets me push the cables right out below the 16T pulley, so I am then able to feed the cable right back through the conduit and meet up with the cable of the other stepper. That said, I want to build my own harness that terminates into a 2x4 JST block to keep everything tidy. I don’t really grasp the series configuration yet, but I’m fairly competent in these things so I know I’ll be able to figure out the answers on this page after some trial and error, but I wanted to ask if it would be easier or better to make a parallel harness or series? FWIW, I purchased the series kit from V1, but all the loose wiring will just give me a lot of grief and I want to build my own from ribbon. Can someone make a suggestion of what would be the best path forward, and if parallel, can you share a diagram for that?

Disregard my previous comment. As soon as I posted it, I went digging around on the site and found the page that says to avoid parallel due to double amp draw etc.
"went digging around on the site and found the page that says to avoid parallel due to double amp draw etc."Yeah... Actually, I did too after posting that and am actually a little more confused. I wasn't sure if it was saying you should use parallel if you're using end stops, which I have every intention of using... and if not, why is it even mentioned in that sentence? hmmm...
