hello Marcus and others,
just wanna give feedback and say thanks:

This procedure works well.
The most important step
(as nearly everytime working with GRASS)
was the g.region settings.
I always have problems knowing my exact resolution
for the target region "res=1 -a YY".
But using a raster map with similar extend and under the same mapset worked well.
Thanks for your hint. A feature this command seems to me very hidden, though.
