I'm here again with the same problem.
Unfortunately, I tried to apply your suggestions, Artur's in particular, but what I'm continuing to obtain is the same: a good castellated mesh, but nothing about the snap fase!
I modified the mesh control parameters; I checked the STL file. The final checkMesh gives me no errors nor warnings! So, I don't understand where the problem can be.
I share again my case:
Now I'm using OF 2.2.1 (but nothing changed in the result)
How can you see in the SHM log file, line 1915, the message "Did not succesfully snap mesh. Giving up." appears.
Any suggestion whould be well accepted
Thank you in advance for your help!

did you solve the problem, claudio?
I have kind of the same problem (sHM doesn't snap -.-).
I also have many doubts about my stl. I made it in rhino 4, and sHM manages to mesh it (badly), so I would think there are not "problems of closure".
I believe there could be problems with some of the surfaces I created in rhino.
what do you mean with "check if your stl is ok"?
how can I do that?
thanks to all ^^

you can check your mesh with the command "surfaceCheck partname.stl".
This will give you back some information about your .stl file. Especially about a closed surface, nearly exact points, not multiple connected surfaces.
You can use this information to work improve your .stl. In my case (Export stl from CAD) this meant to increase the stl tolerance ratio. After some exports i had a closed surface.
For editing closed vertex etc. (dont know the names of all these errors) you can use the filter options within meshlab (filters -> clean repair).
Hope this will give you some hints where you have to gather new information^^
