It's extremely hard to tell in the pictures, but the Minimax FS41ES / FS52ES --might-- have a longer distance between the alignment bolts/pegs when compared to the Felder AD951 (see pic below).? This might allow a slightly easier setup/alignment on the machine and to keep the alignment over time.? However, without anyone doing an actual measurement, it's impossible to tell.
This is just one aspect of the machine and there are many other differences.
