ST-V2 5 axis breakout board
« on: November 08, 2014, 11:28:13 PM »
I have been working with a ST-V2 5 axis breakout board from stepperonline. I have everything working except for limit switches and e-stop. I have read the mach3 manual several times and searched the web for answers on how to configure this board. I can't seem to get the e-stop and limit switches to work. Looking for answers on how to diagnose the problem. the documentation shows the e-stop setup on pin 10.

Here is the link to the documentation on how to setup the board.

http://wiki.midsouthmakers.org/images/e/e2/5axisManual.pdf

when following these instructions I am not able to get the e-stop to work.

I uninstalled mach3 and then re-installed and ran the setup instructions. Still not able to get the e-stop to work. Starting to think that my PC might have something wrong with it.

From just a quick look at the installation instructions E-Stop is configured as Active Low.
To follow their wiring instructions your E-Stop switch should be 'normally open' contacts and only closing the contacts when E-Stop is pressed. Is this the way you have it wired ??

I have tried both configurations and I can't get either to send a signal back to mach3 and trigger the e-stop.
I thought that I had problem with my parallel port so I setup the board on a different computer today. Same issue.
I have purchased a MB-02-V6 from Homann Design. I plan on moving forward with that board.

I'm just setting up my mach3 interface so I could be way off on this, but....

I just configured my e-stop and limit switches. The switches on mine are all normally closed except z home which uses the touch plate.

All my switches are connected to the breakout board through the DB9 connection that tie to the breakout board. E-Stop is pin 1 and 9 on the DB9 I have all the limits and homes (except z-) wired in series and tied to pin 8 and 9 on the DB9. z- is hooked to pin 7 and 9 on the DB9.

Hope this helps some.
If you need the wiring from the DB9 to the breakout board let me know, I'll trace them out.

Oh, one more thing that was driving me nuts, sometimes my ports would work and then other times not.

I discovered the power to the board was not plugged in good and was causing a intermittent open.

There should be two red LEDs lit on the board.

Did you ever get the Limits and E-stop working?

There is a guy selling these on eBay as repaired. He states they don't work as is. He has a web site too I think it is Hubbard cnc or something like that. He state that the inputs don't work as the board was made.

I had the same issue, but the solution is easy:
You have to apply an Voltage on the power supply pins on the right (12V-24V)!

Then you will see another LED near the input pins is active. The Diodes in the optocoupler are not connected to USB 5V won't work without an additional power supply.
