Cura 2.3.1and Print bed Leveling

[h2befjon 1]

Hello,

I have an ultimaker 2 and I did the + upgrade about a few weeks before the launch of the ultimaker 3. I haven't had any major issues since doing the upgrade except for the occasional print head rubbing against the side of the wall when returning home. I tried to fix that by bending the metal tab for the sensor a little forward and it seems to temporarily fix the issue. However, I don't think this issue is related to the issue I'm currently facing with leveling my bed after putting a .15 nozzle. I have tried many times to level the bed but I can't seem to an even layer, I tried adjusting the middle and front screws through the walkthrough and by starting the print. I had some "success" doing the adjustment live but when I abort and reprint the object it does the same thing. I'm using the old cura version 15.04.2 because the new version of cura 2.3.1 doesn't have the option for .15 nozzle and I can't seem to find how to manually input it. Can someone assist me? I haven't had this issue with any other of my bigger nozzles.

What is the thickness of the first layer?

Normally, first layer thickness is set at 0.27mm in Cura, also for prints with 0.06mm layerheight. This relatively thick first layer is to get a robust bed adhesion, and allows for some inevitable tolerances in the glass plate and the print head suspension.
