I installed everything last night and configured the 4th axis in the software. Everything is working nicely (printed a large vase to test the setup). Next step is to find how short I can go on the bowden. I doesn't look like the bowden gets stressed much, even on my temporary and fairly rigid extruder mount.
Some people mount the extruder on gimbals, so that the output direction of the Bowden tube can swivel to accommodate the XY position of the effector.

I thought about a gimbal, but an elastic band seems like a simpler solution.
@dc42 The rail I am using for the 4th axis is too short, 400mm(build height is 340mm). It was a spare I had lying around. Is there a way to limit the movement of the 4th axis?

With an elastic band or gimbal, it is the effector that is moving the extruder. I want to eliminate any interaction between the two, so I think I am going to hard-mount the extruder to the 4th axis.

@bartolomeus, Thanks, looks good!
I certainly add the wish for a 4th axis and flying extruder to my build-wishlist!If you think trial and error is dangerous, try routine. That's even more so!

No, like the other 3 towers it will move as far as necessary to keep the correct distance from the effector.

Actually, I followed your advice (very long rod length) from another thread (z tracking camera) and now the 4th axis only follows z height and doesn't adjust for the distance between effector and extruder. It's a temporary fix untill the longer rail arrives.
