Thanks for your reply and your great work on Cura Daid. Great that you'll take the feedback to work.
Attached you'll find some pictures of the final print, with meshmixer supports included. I'm really,really fond of these after this first print: They're very easy to break off, don't take much time/material to print, and do provide adequate support. As with the concave parts, these also are probaby more difficult to generate, as the topology of the object also plays a role. If you're going to spend serious time rewriting the support this might be the way to go (please add a function to bring the supports to the outside of the part on the buildplate then).
(first pic shows two failed attempts: 1st one with 'wavy' supports had material feed problems, the 2nd one was with fix horrible B, while I should've chosen A).
As for bridging: I'll do some experiments just like gr5 did, I think my fan is very off-ideal at the moment to do this well (one blade has broken off and I'm waiting for the replacement from Ultimaker Central.
And well... dual head, water soluable supports: :wub: ... however no extra money atm... first for a sabbatical (and afterwards a heated bed).

Interesting case, I did not think about this case when doing the new support material. It is clearly a problem for break-away support in some cases.
Note, the old method was broken in many ways, many ways that do not impact you. But it has quite some issues.
While there have been complains on the support material (as with every change) this is the first time someone makes a real case. So I'm planning to do something about it. I might be adding an option for the "wavy walls" support. As cutting the concave polygon into multiple convex polygons sounds easy but is difficult to do for all cases in a good way.
Note, the new support material is awesome with water-soluble support material.
Finally, most reprap parts are designed so they are printable without support material. I would rotate the X-END-MOTOR by 90 degs so it's flat on the biggest area. Bridges should be able to take care of all the overhangs then for both objects.
