Hello.
Now i m achieved sufficiently smoothing behavior of authomated trains using fully authomatic in Viessmann Commander.

There is a small clip:

What do You think about it?

What's Your opinion?

---------
Thanks,
Vadim.


Hi Vadim,

very smooth movement.

Now I understand, why You need very good motors and good contact between rail and wheel.

Greetings Michael Peters
PLEEZ hold that camera steady, so one can see something!

Felix
Hi Vadim,

that looks very good! Which kind of tracks did you install on your layout? Is it selfmade?

Regards...Pierre
Hello to all !

Yes, Michael, i need good contacts and motors with stable BEMF.
(I think I will use programm stabilisation of precise braking too, but Viessmann Commander, which i use now for automation, still cannot perform such stabilisation due to program restrictions )
Mainly,  TWO things would be enough for good contacts :
1) You must have as minimum  as  4 loco axles per loco being well-springed (each wheel separately ) and pickuped (how to made it - i early  showed here with detailed pictures and videos:
http://www.trainboard.com/grapevine/showthread.php?t=118334).  
Additional powerpack can significantly improve anti-dust properties!
For 3-axle(pickuped) electrical locos (for example Trix E-40/140 or Roco BR101) You must  make working catenary in parallel, connected to power cap via rectifier ( 2 diodes ),  in aim to work with reverse loops. For 3 axle diesel locos - use 2 locos  in parallel.
2) WELL-Cleaned rails and wheels.  The main rule: Polish rails and wheels well,  when You starting Your layout,  and clean it by sterile alcohol and NEWER TOUCH IT BY HANDS!

Felix, i understood You. My  camera has  spatial instability. It was all due to long  focus and abscense of any support. Believe me, i cannot do better with my hands.
What do You advice for me? May be gyroscope support needed? I dont know what's would be convenient for clips?


Pierre, i used Code 55 ME or Atlas tracks.
Some parts was painted from syrringe and airbrush (6 stages ), Write me, if You interested, i ll  told You my algorithm.

Thanks,
Vadim.
don't zip the cam around to here and then immediately to there an so on, as you do with your eyes. just hold it steady, and let the watching people move their eyes.
when you move the cam, do it slowly. and, maybe you will use short focus, but move closer to the object.

This one I've taken with my digicam in video mode, with short focus. I just had it in my hands, and walked beside the layout while taking the video.

Felix
I see, Felix. May be it is all because my long focus.
Your video also has oscillation, but they are less than my ones.
By the way,  You have an extra - big layout and extra long thains !  :)

Thanks,
Vadim
