Engraving Center of stick Font

(Original thread by Colin Gilchrist)

Engraving is not designed to pocket with a regular endmill. It is designed to take a V bit tool (usually 90 degrees or less included angle) and route out the letter. You need to use a tool with a larger diameter than the letters (I would say at least 30% wider).

Try this quick example:

Use Create > Letters

Change the Font to MCX BLOCK FONT (not box).
Letters: TEST (use caps)
Alignment: Horizontal
Height: .5
Spacing: .1

Put the starting location of the letters at the system origin.

You should now have the letters TEST spelled out in outline form.

Now create the toolpath.

Toolpaths > Engraving

Define a new tool, make the tool type and "engraving tool".

On the engrave tool parameters tab enter the following parameters.

Diameter: .002 (this is the inner tip diamter)
Outside Diamter: .5
Taper angle: 45
You can leave the defaults for the rest.

Under the engraving parameters
Top of stock: 0.0 abs
Depth: -.5 abs

Under Rough/Finish tab:
Rough: disabled
Smooth Contours: disabled

When you generate this toolpath, you will get a warning telling you "the programmed depth of cut for this operation is too deep for the selected tool. The maximum depth for this tool is -.2495".

Leave it set to "use maximum depth for selected tool" and let it generate.
