1. The entire machine, but I didn't actually say $500. I said that was my
target, and I might have to charge a bit more.

2. The entire machine, including steppers.

3. The entire machine, including software.

4. Not at this time. The controller understands path commands from the PC so
a program could be written I would imagine, but that is not the target for
the unit. The current PC software reads HPGL and Gerbers.

That is the entire machine, you supply only an old windows PC, a power
supply and materials to cut. It is assembled and tested and little or no
technical ability is needed to set it up and run it.
