I’m doing some fine detail work (topographical maps) and there are places that have some residual fuzziness or places that need sanding. I’m wondering how I can address this.
I will say up front that I probably need to readjust my Shapeoko 3, tension on the belts is good but the tension on the rails could probably be tighter. I don’t think that’s the whole issue though because some things I do come out perfectly.
I’m using ArtCAM for this round of things. I’ve attached some photos of a grand canyon project I’ve been working on, pictures are of two versions. You’ll see in some of the cavities there are stray bits of attached chips and/or sawdust. Tiny curls mostly.
I’ve been playing around with different finishing strategies but I’m not consistently getting what I’m looking for. I’ve played around with raster finishes, x/y raster, radius cuts, the direction of cuts, direction of cuts as the relate to the grain of my stock. There’s something I’m missing. (And I’m fully open to the idea that my cutting speeds or some other basic thing is wrong with my jobs.)
Here are some pics. I can post any other info you’d like, just let me know what you need to help me isolate this.
