Interesting, thanks muchly. 

You say if inkscape uses 90dpi and illustrator uses 72dpi, illustrator
to inkscape would give you 80% (72/90) - illustrator puts in 72 points
to get a full length, but for inkscape 72 points is only 80% there.
Inkscape to illustrator would be 125% (90/72).

In my case this would mean that inkscape created the DXF at 72dpi,
whereas the laser cutter imported it at 90dpi. Worth checking up on,
if there is a dpi setting in DXF.

Thanks,

Volker
