hi, I’m starting to do the wiring. I have 1.68A steppers. What kind of connection should I make with a MKS sbase 1.3? Series or parallel ?.
Series
this way?

I’m wanting to start a MPCNC or LowRider build shortly and have a few questions along similar lines… My weakest knowledge point to building this is in regards setting up all the electronics. One question I have is this - the MPCNC uses quite a few stepper motors which is fine, but i’m curious how to set them up in the sense that the X&Y axes coming off the control board each have 2 motors then you need to wire the motors in series as shown above, BUT, do I need to have a bigger motor driver (twice the amperage rating) to run both motors at same time to maintain the full 70OzIn. holding forces?? I am mostly just guessing based on what makes sense in my head in regards to how to drive multiple motors of a single output on the control board and driver (i’ve never done this before, perhaps some drivers support 2 motors by default?)
Thanks!
Series uses same amps twice the voltage, perfect for our low voltage high amp drivers.

A quick post to see if my understanding of the stepper motor wiring is correct
I hope my brain as finally understood things, the picture I have attached contains writing to explain my thinking. Would someone take a look and comment, please
We do not do it that way anymore, that is parallel. We now use series.
Thank you Ryan,
i am now lost, I think I need more research…

Finally the penny dropped. After looking at the above diagram if stepper motor wiring for some time, I had a eureka moment. It then jumped out at me. This is my explanation,
Stepper 1 runs as per normal, stepper two looking at the diagram is on the same cables for runs in reverse.
Now to me this is just obvious, then why oh why did it take me so long…
answers on a postcard please!
Im still not certain, I have described it correctly…
regards
Sorry.
That would be correct if you wired it in parallel. We do not do that anymore. Have a look at the page I linked we now wire things in series. Which translates to the coils from each stepper are wired inline with the next.

Hi Ryan
As I said I don’t think I explained it correctly, I have attached a diagram labelled Stepper 1 & 2 with Windings 1 & Windings 2
[attachment file=65055]
Using the colours as per Diagram for information ONLY.
Red wire from X or Y axis connector enters Winding 1 of Stepper A, it exits Winding 1 via the blue which is connected to the red of Winding 1 of Stepper B and exits via the Blue of Winding 1 of Stepper B and connects to the X or Y axis of the Ramps Board.
This is repeated for Winding 2 of Stepper A & B… Wiring accordingly.
answers please
The Wiring pairs will be identified on the stepper motors using a multimeter.
Yes
Finally, I have explained this correctly…
Thank You Ryan
This appears to be wrong
The above is wrong, the diagram below is correct and tested. Remember to use the colours for an example and follow the wiring pathways.
Thus is correct and tested

alternatively, if wiring causes you so much confusion and frustrations then simply order the wiring pre-done via the shop, it will save you a lot of time

The first one. Notice that winding 2 is reversed between the two motors, that’s what you want to get the motors to spin in opposite directions, which is what you want if your trying to sync two motors pointing in opposite directions.
Hi guys
This one is correct and I redrew it to aid anyone as I had exactly the same issues. Windi Two is reversed as it is opposed to motor one and so must run in reverse. Follow this and you won’t go wrong.

I have added that to the wiring page, thanks.
