I've been doing some tests with a pump I've got and written about it in the drip governor thread. The pump in and out test I just did could well be a solution to this as well. http://3dprintboard.com/showthread.p...rst-hack/page5

I've been thinking about this problem for a VERY long time now and I think I may have come up with a simpler solution, it seems to me that the easiest way to deal with the surface tension problem is to simply displace the water in between layers, so on the side of your build tank you have a vertical pipe with an opening at the bottom, in the pipe you have a piston hooked up to your solenoid, the piston is set so that the area inside the pipe while the solenoid to the solenoid at full travel has the same volume as 1mm thick layer of your build tank, then as each layer finishes being printed the piston extends displacing exactly 1mm of water and then resets bringing the water back to its normal height to be raised by the drips to the next layer print by having the opening at the bottom of the pipe it should eliminate the rippling in the build tank and just cause the water to move up and down once every layer, if you want to take extra precaution, make the pipe double walled to prevent any vibrations from the solenoid from disturbing the water.
