2.3 for printrbot: cura is placing the model too low and I can't move it.

I'm trying 2.3.0 (on ubuntu trusty) for the first time with my printrbot simple. The display now has a drawing of the metal bed of the printrbot, which is pretty cool. However, the bottom of the bed drawing is at z=0 and the top of the bed is at a higher Z. When I place a model it puts the bottom at Z=0 so the model actually starts below the bed. Sure enough, when I print the model that much of the bottom is chopped off. I tried to manually move the Z up to a positive value but when I put a number in the Z box nothing happens and the Z move value goes back to zero.

I had just installed 2.3.0 over an old 15.04.6 so could some old machine settings cause this problem? Where are machine settings stored in linux?

There are no machine definitions copied from 15.04 to 2.3.0. Someone from the comunity contributed the printrbot machine definition, so it could well be that there are mistakes in it (we don't do QA with non-ultimaker machines obviously)

A fix could be to disable the "drop objects on platform" preference.

I have prepared a "pull request" so the alignment of the mesh to the buildplate will be fixed in a future version: https://github.com/Ultimaker/Cura/pull/1088

Thanks for the fast response.  Is there anything stopping me from building the stable version with this pull request?

Edit: Never mind. I see it is just in the machine definition. Thanks again.
