I might get a bit impatient if I have the impression that others get an answer faster. Sorry for that.

It’s not unusual to get that impression. It depends on the current attention, capacity and mood of the few who can answer your questions.

So the problem is still \hfill that the last paragraph is not on grid in the new and the old version (and comma).

Grid is not as easy as it looks first. Low level tricks like fills or skips can mess it up.


Maybe \startlinecorrection helps… (No, it doesn’t.)

It also doesn’t help to add a \blank or \par after \vfill.

I know it, i tried it. And I tried \snaptogrid \vbox {}, it doesn't work too.

Only counting empty rows and set the number in \blank[ *big] works!

You need a fixed space (multiple of the line distance) between the text blocks and \vfill is a variable space which isn't what you want here.

TO get the desired space between the blocks you have to measure the height of the text at the bottom and calculate the number of lines which have to be added in the gap. Below is a simple solution which adds the required number of \blank lines.

\def\PlaceAtBottom
  {\par
   \dowithnextbox
      {\scratchdimen\dimexpr\pagegoal-\pagetotal\relax
       \ifdim\nextboxht>\scratchdimen
         \page
         \getnoflines{\dimexpr\textheight-\nextboxht\relax}%
         \dontleavehmode\blank[\number\numexpr\noflines-2\relax*line]%
         \unvbox\nextbox
       \else
         \getnoflines{\dimexpr\scratchdimen-\nextboxht\relax}%
         \blank[\number\numexpr\noflines-1\relax*line]%
         \unvbox\nextbox
       \fi}
      \vbox}

\let\stopPlaceAtBottom\egroup

\def\startPlaceAtBottom
  {\PlaceAtBottom\bgroup}

\mainlanguage[de]
\setupbodyfont[libertinus, 12pt]

\setuppagenumbering
  [location={footer,middle}]

\setuplayout
  [grid=yes]

\showgrid

\starttext

\samplefile{lorem}

\startPlaceAtBottom
{\sl\samplefile{lorem}}
\stopPlaceAtBottom

\page

\dorecurse{4}{\samplefile{lorem}}

\startPlaceAtBottom
{\sl\samplefile{lorem}}
\stopPlaceAtBottom

\stoptext
