I believe that you’ll have better luck w/ this if everything is constructed in the same way.
If you’re not familiar w/ Bezier / vector drawing programs, I’d suggest doing some tutorials — we do have some for Inkscape: http://www.shapeoko.com/wiki/index.php/Inkscape#Tutorials_and_Examples
This should be straight-forward to make — I assume that what you want is:
- two drilled holes to fasten the piece in place and to allow for a cord to be passed through
- text which will be V-engraved
- an outer perimeter which will be cut out to separate the piece from the stock.
Okay, assuming the 1/2" x 1/2" information is correct, this should be pretty straight-forward:
- launch Carbide Create
- initial setup — machine, material, &c. — I’d set this for a 1" x 1" blank so as to allow for easier zooming, material thickness was set at 1/8" (3.175mm) (as opposed to the less than 1mm of the sample file which is a blank thin enough I’d worry about the edge cutting a person, or possibly being carved through when V-carving)
- create a circle, set it to begin at 0.125" and 0.125" and be 0.75" in diameter (you’ll want your blank to be larger to accommodate clamps, and I found the 0.5" diameter a bit crowded w/ the two holes)
- create a second circle, since Carbide Create doesn’t have a drill function, make it large enough that it will be possible to pocket it out, assuming a 1/16" endmill, we use the appropriate radius, multiply it by 1.05 to get the needed 10% fudge factor and round up: 0.066" radius
- duplicate that circle (control c) and place the two appropriately
- set the text — note that you will have to manually adjust the placement of each bit of text as it’s made so that it will be visible / selectable — note that for the text, so as to give the smaller text the same visual weight as the larger, I set the former in bold.
- adjust everything as necessary
set CAM for three operations:
- select the two small circles and Drill w/ a pocket contour
- select the text and do a V-carve
- select the outer circle and do a contour along the outside to cut things out
When you actually cut this out, I’d suggest putting plastic or aluminum screws down through the two holes.
The engraved text seems to be too small for the preview to show well, and I’m at work so can’t try it out.
