Newbie Problem

Post by ehsmith »

I'm somewhat frustrated by the tutorials. They are too much stuff at the beginning.
How about just making and machining a simple "Dome" and then maybe a raised/shaped "Rectangle", etc.
So there is a sequential order to the learning. I'm slowly getting some of it, but it's been
very frustrating. I've done all the early tutorials and the first 6 that came with Aspire
and even though I'm getting some of it, I feel very insecure with what's been presented.
I don't think I could construct and machine even a simple shape on my own at this point.
I'm a relative newbie to CNC. I've been using VCarve Pro for about 1 1/2 years, but that's the extent
of my experience. :oops: :cry:

Have you tried going through the pdf tutorials, while doing it yourself?
One of my old instructors always said, "Adults learn by doing". So don't just watch, actually follow along and do the model.

Hope this helps,
Tim

Hey ehsmith,

Where are you getting confused are stumbling.
Don't hesitate to ask questions. We all are still learning Aspire.
Have something that your wanting to accomplish?
Maybe we can break the piece down into sections and put it together.
Maybe there should be a Work In Progress thread.

I think my main problem lies it trying to figure out how I would actually machine
what is being shown on the tutorials.
I know in the tutorial I went through yesterday, they said there would be machining
in a later tutorial....
I think I get the concepts, but it's the practical application that's concerning me.
I would like to design and machine simple shapes to begin with.
That's how I learned to program and machine in 2D.
I appreciate all your help and suggestions. :?

ehsmith,
I've take an 8 inch circle and created a dish with the depth of the dish depth of .600
I've also included the tool paths which include a:
roughing pass with a .250 endmill
finish pass with a .090 ballnose

In order to machine a relief in Aspire you need a boundry around the releif.
You can draw any closed shape vector around your releif.
I used the original circle that we created the dish with and used it as the machining boundry.
Select your machining boundry.
Then open your toolpath tab.
Then select "Create 3D Roughing Toolpath" icon and fill in your parameters.
Then select "Create Finishing Toolpath" icon and fill in your parameters.
Save with your post processor.

Thank you. That's the kind of beginning I was looking for.

I'm slowly getting some of it, but it's been very frustrating. I've done all the early tutorials and the first 6 that came with Aspire and even though I'm getting some of it, I feel very insecure with what's been presented. I don't think I could construct and machine even a simple shape on my own at this point.
Hang in there and don't be afraid to ask questions. I think it was about 30 or 45 days before I had the AH-HA! moment where it made sense and started to feel as natural as V carving.

Aspire is a stunning product. The other day I was able to help out someone who needed a 3D design for a project. I was able to provide him a design in under 5 minutes. That collaboration can be found ->here

One thing that helped me was to take a very basic V-carve design and the change it into 3D. For example:
Start with V-Carving
1. open a new project
2. draw a box and type your name as you would if you were going to V-carve it
3. select the letters and toolpath with a 90 degree bit and preview. This should be the same as V-Carve pro
4. Delete the tool paths and go to the next step

3D Carving
1. select the letter vectors and click on "Create Shape from Vectors"
2. Choose the angular (pointy) profile and specify a 45 degree angle
3. Click "Add"
4. Press the <Page-Up> or <Page-Down> keys to look at the 3D view along with the vectors. Note how the letters look like a reverse V-Carve. This is a "working model"
5. Click "Make Component" and use the default name (the working model has been changed into a component)
6. Click "Close" on the Create shape dialog box
7. Select the box vector (this is important)
8. Click the Switch to Toolpaths Tab button
9. Click on "Create finishing toolpath" and choose defaults ("OK") in material setup
10. Specify a 0.125 ballnose bit
11. Click Calculate (it may take awhile)
12. Click Preview toolpath

You have now seen how to make a sign with either V-Carve or reverse V-Carve (prismatic) letters.

Now try this approach with other basic shapes. Try them as a V-Carved design, and then try them as a prismatic or domed shapes.

Play with base height.
Use a circle or ellipse rather than a square bounding box.
Watch what happens when you choose Subtract rather than Add

Ask questions and post examples of things that are confusing.
Post examples of small triumphs.
There are others like you with similar questions. Your messages help them too.

Yes, you guys are awesome. These last posts from guys telling me exactly how to create and then machine simple
things are just what I needed.
Thank You,
Homer :D

O.K. This is getting at it..
How about if I just want to machine a circle with a 2 inch diameter that is domed and 1/2 inch deep.
I have no problem doing the drawing/doming part in Aspire.
What do I need to do from there to machine it?
I'm getting there thanks to all of you.
Thanks again,
Homer :)

Homer, Am glad its helping,
You need a machining boundary around what you intend to machine.
Like in my first sample, I just used the original circle that use to create the dish. And then to the toolpath tab.

But if you've deleted that circle that you used to create it, and haven't made your dome into a component yet. Then do so
Then you can select the component in the 2d frame and use the trace feature to create an outline of your dome and use that outline as your machining boundary.

O.K., so the main difference is the boundary around whatever
I'm machining and from there choose toolpaths?
I read another thread here about using roughing tool path
first and that was a real eyeopener for me also.
Thanks again,
Homer :)

Homer,
Yes you might need to run a roughing toolpath first, But the process is the same, in fact you can use that same boundary.
If you do a roughing pass, this will remove most of the bulk and allow you to use a small finishing tool with less breakage.
