Sorry if this is a basic question. I have almost completed building my first 3D printer and I'm trying to get the software sorted out. I downloaded Pronterface and can't get it to run. I'm using windows 10 and have both Python 2.7 and 3.5 installed. When I run the pronterface.py program I get a message that says ImportError: no module named numpy. I am very confused. I think I have it for python 3. I entered pip install numpy and it installed. If I start python 3 in the command prompt and enter import numpy then I get a cursor. I'm assuming that I have numpy for python 3 but not 2. Here's where I'm lost because I can't find a straight forward way to get numpy for 2. I hope that made sense. I'm trying very hard to learn all this but starting at age 40 I'm a bit slow! Thanks!
