OK Now What?

I did a mini mill conversion and everything seems to be working well,
but I have no idea what to do with it now. Where do I start? Should
I do some sample drawings in a cad program and then try to convert
them? Should I attempt to run the samples I got with TurboCNC? I
think I need to look at the files first and make sure I'm not crashing
anything right? Do most people edit files manually? I am hoping to
get to where I can do some simple engraving but I dont know where to
start. I have TurboCAD and TurboCNC. Do I save my TurboCAD drawings
as DXF files and then try to load them into TurboCNC? I know this is
alot but if some one could jot down a simple step by step procedure
for going from Cad to code it would help alot. Thanks
