Simple routing along a path from an SVG

[dtiner12]

I have a project where I'm simply trying to route along the path. I made an SVG so that the lines are the same width as my cutter (and tried wider with same results). I'm using a 2D contour and selecting the bottom of my cutout, but it only mills larger areas where the lines happen to overlap. See screenshots for the model and then the resulting toolpath.

I see no reason why the cut should not be physically possible, so I assume I'm missing something. Is there a better way to do this? Something I'm missing about setting up the toolpaths?

Some things I've tried...
- I saw issues with not having room to ramp in. I set ramp type to plunge to resolve it and my setup/operation have green check marks
- I tried to use a slotting operation but my bottom surface is not selectable with that operation.

I've played around and seen issues with . I set ramp to plunge.

Please attach your model so the Forum users can help you out.  Hard to show anything from just pictures.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Thanks @jhackney1972 I've added the model

Your issue, at least as I see it, is your end mill is the exact size of the slots.  I changed to a 3/16" end mill and took off Stock to Leave and it seems to work just fine.  Model is attached.

Is there a good workflow for starting from a 0 thickness path and making sure all the lines are the same thickness in Fusion? Or is that just something to solve for in the SVG

Using the attached model here I'm trying

- Going into the surface workspace

- Selecting the outermost line of the letter F (just as an example)

- Extruding -0.25 deep (for some reason I sometimes get errors here "multiple wired body is not allowed")
- Selecting the bodies from this extrusion

- Using thicken to cut 0.25" wide symmetrically.

I get errors with this at different points somewhat inconsistently, especially with the more complex geometry of the part I routed already in the screenshot.

Are you asking me a question, you are writing to yourself?

@jhackney1972 I'm asking a question for you or anyone to answer at their discretion. Didn't tag in case the notifications are bothersome

I hope I am understanding what you are describing in your text.  Take a look at the Screencast and if I missed it, let me know.

By the way, you are piggybacking this question on the previous one.  Did my solution work for you?  If so please mark it so by selecting the Accept Solution icon.

@jhackney1972 Thank you! That works for the letters. It seems like the more complex part isn't so straightforward but may just require more trial and error.

Hi,

I would engrave something like that.
For this I choose a suitable V-bit and the whole sketch.
The engraving depth is then determined by the distance of the parallel lines and the angle of the V-bit.
Different depths can be realized with different V-bits.
However, if you want to mill with an endmill, you can use trace tool. However, only one center line is required for this.

@g-andresen thank you, the trace operation is exactly what I was trying to do! It just follows the svg paths with the end mill without having to finesse model to match the tool. I'm cutting square channels to fit LED lights, but the V-bit and engrave suggestion will help with another project I have coming up.

For any future searchers, watching this video helped me.
