Incomplete Text Toolpaths

I'm trying to CNC a sign for a potential customer, and I am having difficulty getting the entirety of the text to cut. I attached my file and a screenshot of the issue I am facing. Essentially, the cutter is not finishing the letters entirely. I am trying to use a 1/8" bit and some of the gaps (on the letter 'a' for example, are >.125" wide). I also have 2D Contour 4 set up for rest machining, and it is not catching these gaps. Any possible solutions?

Looks like a simple issue of the tool being too big for some of the gaps, couple of ways to do it but because of the odd Font you have used where in some areas it is wider than your 1/8th tool and in other areas narrower, so you could try to set a smaller tool in Fusion in your Contour and then actually put a larger tool in the machine then it will follow the shapes but usually doing this results in some awful shaped letters so I wouldn`t recommend it!!

You could try using the Trace strategy annd using the Climb mill offset but although you will get the shapes you may end up with little areas where the letter is too wide and a small area is not machined.

 

My way would be to use a smaller tool, possibly your 1/16th and use the 2D Pocket, I don`t know what your material is and how fast you can run your spindle but I would suggest that you have a look at the attached file and play around with the entry types and the "stepover" value till you get the least amount of passes but with all material removed, I just used the Zig Zag to see if it worked, you may have to do multiple depths etc but doing the 2D pocket you will get the correct shape of your lettering 🙂 🙂

Maybe you should try something opposite? Single line fonts(.shx extension in Font dialog), Trace toolpath and maybe slightly bigger tools? Those letterings does not look very artistic or something.

I have tried using smaller tools, in fact, I have rest machining activated, and it still seems to leave portions of the text uncut. It's as though Fusion thinks that the tool in the toolpath is too big, and then when analyzing that same toolpath for rest machining, Fusion decides that it was the right size.
