If you are interested in Flashcut, try the demo program from their web site. I have no relation to Flashcut whatsoever except as a customer. This is the newer V2.0 demo. The software is very customizable, and will present you as the user with a large variety of views and configuration options. Note for the demo I ran - the machine envelope (cyan outline) is temprarily set up for a Y-axis of roughly +3, -3, while the Z and X are ignored. The simple G-code editor is easy to use. Of course, when everything comes together, Visual Mill will generate the G-code for me. Flashcut will also import DXF files.
Weird, every time I see a screen shot of a Windows program on the web, I always try to manipulate it by clicking buttons and such. So if you try to click on the software screen, sorry. ;-) To see the MPEG video of this "cut" - G-Code test MPEG video (xaxis_g.mpg) 1.0 mByte
