Toolpaths for Circles not smooth

[jfellows46 (Jonathan Fellows)]

Hello, question here - I have a Shapeoko 3XL, using Carbide Create/Motion. I know that Carbide Create doesn’t use true arcs/circles when creating tool paths, but I happened to notice recently like it felt like my circles were not as smooth as they used to be. Maybe it’s always been this way and it’s just my imagination.

This screenshot is showing the toolpath generated for a 0.20" circle pocket using a 1/8" endmill. The toolpath looks basically like a hexagon, 6 straight lines. Should it be this rough? I was thinking that it should be a series of shorter segments.

Again, maybe I’m overthinking it, just looking for either confirmation, or input on if something is asmiss.

I’m running Carbide Create build 778.

Thanks!

I get the same. I suspect it’s just a display issue with a very small circle

What does your simulation look like? (make sure the enable View → High Resolution Simulation)

If I look at the G-code the circle is represented by 60 linear moves, not 8

Ah yes, thanks. I see. I do see the 60 moves in the G-code. My simulation looks like the below.
thanks - I was just overthinking it!
