Hi all, Would someone like to share his/her experiences
with a Roland MDX-15 milling machine?
Sure, I have one. I find it an excellent scanner and a pretty good
mill, for relief work in soft materials.
All of this is very new to me. I have been reading information
about Rhinoceros, Virtualmill and a Roland milling table.
Are you sure you don't mean "VisualMill"?
It is difficult, as the about all sorts of systems
is abundant. Excuse me for asking a simple question: why do people
use both Rhino and Virtualmill?
Rhino makes the "virtual" 3d model. VisualMill translates that into
a series of directional commands the Roland (or other CNC machine)
follows to cut out the part.
What are the pros and cons of Rhino?
It's relatively easy to use and affordable, but very powerful, and
it translates between a large range of formats. The newly added
ability to manipulate shaded forms directly is a big plus. But on the
other hand, it is mostly oriented towards "NURBS", a spline-based way
of representing 3d forms. This is good for representing complex
curved surfaces, and is more accurate than the usual way of
constructing them, which uses a series of triangles of a certain size
attached edge to edge. Rhino doesn't have many tools for dealing with
these polygon meshes (although it can create DXF or STL meshes for
export to other programs). Polygon meshes are more flexible in the
way they can be structured but are also more memory-intensive. This
is analogous to the difference between vector graphics and bitmaps,
I guess- vectors are smoother, and take up less bandwidth, but it's a
lot easier to make bitmaps of some things.
Does anyone has experience, tips - all
relevant would be very welcome. Thank you for reading.
If you're thinking of getting into this, Rhino and a Roland MDX-15
wouldn't be a bad place to start. Roland includes some software
(actually an early version of DeskProto) which will translate your 3d
model saved as STL or DXF to toolpaths, or it can scan a model you
make in clay or any other material, then scale it down and carve it
out, which is nice for people who have an easier time actually
sculpting a part (at a comfortable scale) than trying to model it on
their computer. The spindle that comes with it is not very fast, as
was pointed out. But it isn't too hard to adapt a higher-speed
spindle to the z-axis slide, as was also mentioned. You might wait
to get VisualMill until you got used to the workflow, and then add
some of its more sophisticated functions to your cutting routines.
