i created a new branch "turro-DOF-1" on Github including your recently changed files.
Doing first tests, there seems to be a problem within the new algorithm. It only solves the parts with distance 1 from fixed Part. Other parts beginning with distance 2 are not moved, but solver gives message "system solved". I attach 2 test assemblies which show this effect on my machine. Perhaps it is only a small bug.
After a quick look at the report-view, the DOF calculation seems to be correct. Only processing of the resulting chain does not work.
FYI: 6DOF-Platform example is solved without any problems. Stage 5 of your new algorithm seems to work.
If You press several time the solver button You'll get it solved one piece at a time.
The rigid misplaced simply has not been updated the placement. Tonight (if not drunk ) I'll look for a workaround
