Patrick,
The CNC baptism is easier than the 3d scanning baptism<G>
With my machine software, Working with Autocad files is not a
problem, except that acad DXF is a transitive format.(Always
changing) So there's a learning curve until you find what works. But
once you do, then it can get pretty seamless for 2 or 2-1/2D stuff.
The machines will come with dxf, bmp and hpgl import, so getting
toolpaths from other sources can be simply done.
The mdx15 uses a piezio scanner, which works by vibrating a needle,
and then paying attention to the frequency damping which occurs when
it touches something. It's a good technique for small detailed items.
I've been trying to hunt down the patent path for this to see if I
could offer it. (Roland hasn't been very amenable to selling just the
scanner. At one point I was going to buy complete picza's just for
the piezio...) Until I get that worked out, we have to make do with
the renishaw type probe, for which the patent recently ran out. (It's
not a bad choice, but can be slower at sampling the surface.) The
machine software includes the ability to scan/probe.
My more expensive machine is much sturdier than the Mx15, with 16mm
steel shafts on all axes. It is also more open in the design, and
will lend itself better to user additions and larger work. This is
also true of the 1000 buck machine, but that machine has 3/4 shafts
x/y and 1/2" in Z.
For your small pcb's the roland won't be a bad choice. Some have
found the spindle motor limiting. And the software is definitely in
the "bundled" category<G> Send me an email offlist, and we can
discuss your needs in more detail. I may have something that makes
sense for you.
