Hi 9fingerscnc,

I am newby with cnc and i also bought from STEPPERONLINE the same breakout st-2 + 3 axis nema 24 kit. You said everything was working except limit switches and e-stop. How did you wired your board? Did you follow the "Typical connection" of "comon anod(+) connection" between this board and motor drivers? (M542T). I mean did you joint in only one wire the (Pulse+) + (Dir+) + (Ena+)  from driver to 5v conector at board? And each (-) from the same to each conector at ST-2 board?
I am dealing some problems with connections. I follow the user manual recomendation of common positives. But i also saw at youtube people conecting with common negative wires. So, i am not sure what to do becasue it seems no one or other is working. But i am still trying some solutions.  Could you let me know how you did yours?
And about your issue? after this time is already fixed? how you did that?
Regards,

Hello hersche

Do you mean that you have to supply a voltage superior as 5 v ?

THANKS

Hi Carmelo,
  Yes, you must connect 12 to 24 VDC to the terminals indicated as that is required to operate the indicated inputs.
5V will not work.

hello all, Tweetie, how are you my friend?  I am having the same problem.  The E-Stop just does not appear to work as it is supposed too.  I too have tried all of the settings, including connecting to P11 and changing the settings on the inputs,  but no joy.  If anyone has any ideas, please let me know, I am totally
 out of ideas.

Hi Larry,

Nice to hear from you again.

There are disadvantages with that particular board...
1) It needs 12-24 volts in order for the EStop (or any other inputs) to work.
2) The EStop switch needs to have 'normally open' contacts (most are 'normally closed' contact).

Perhaps a different breakout board would be the best option ??
