Help needed

Hello,

I would like to build a command station. I use an Arduino Uno, a Arduino Motor shield and the DCC++ software. In my test setup I run the Rocrail software on Windows.
I connected two tracks - one for programming, one for running the locos.
What happens is: when I put a loco on the programming track, I can read the CV‘s and also modify them. But when I move the loco to the ops track it doesn‘t move. No reaction at all.
I measured the current on the ops track - seems ok. I also watched the signal with an oscilloscope and it looks fine.
Where can I test from here?

Regards,
Siggi

 

are the four lights showing on the arduino motor shield .i always use jmri

 

Yes, the four lights on the motor shield are on.

 

...hmm...
I build the stuff exactly as shown in the video...

 

a plus and minus to 1 track .
b plus and minus to 2nd track
use at least 15v input to shield but make sure you cut vcc trace underneather plus brake traces
never used Rocrail software.download latest jmri and use dcc++

 

You might try the diagnostics, from the Arduino serial monitor:

And, you can use throttle commands from the serial monitor:

I had an issue like this last week. The loco was in consist mode.
