I know I posted about Logistics Pipes recipes not showing up sometime last month. I updated our server to 2.9.4 and the recipes still do not show up in NEI. So I did some testing and from what I can tell the version of LP that you are using (0.9.3.99) is not compatible with the version of Buildcraft you are using (7.1.16). In other words it doesn't recognize BC robotics even though they are there, which is necessary for the recipes to show up. For my own testing when I used a newer version of LP (0.9.3.114) the recipes worked fine. So currently that's what we are using on our server and clients in order to have Logistics Pipes.
