The attached image shows two circles created in a new CC file. Jagged, uneven blue lines (especially in 12mm image) show up in Simulation View, and the final pieces cut out on my Shapeoko XXL. Using CC version Build 764 on the Mac. Any reason this is happening in small circles?
This is caused by an optimization where things are converted to polyline so as to draw more quickly.
If you view in 3D using a current version:
Please try the nifty new beta:
Or in a 3rd party G-code viewer:
or actually cut things you will see that they are a bit smoother than that, and if you check the G-code:
X50.964Y30.178
X51.098Y30.398
you will see that the line segments which are actually cut are very short:
compared to the ones used for the Toolpath pane preview:

Will,
Thanks for the info. Attached is a screenshot of the simulation Beta Build 774.
Seems jagged to me. Don’t understand why the lines are jagged only on smaller circles.
Because Build 764 uses a 3D preview optimized for quick generation.
Please try the new beta.
The above image is from the new beta 774.
Post your file?
It doesn’t match what I got from 774.

In the 2D view, we need to simplify the toolpaths or the display slows down, so they end up being less smooth than what gets output to your machine.
In the 3D view, the toolpath lines are rendered at full resolution, without any simplification.
How do I get to the 3D view?
“Simulate Toolpaths”:
Note that how many pixels are used will vary based on Stock Size.
If you reduce the stock size to the bare minimum:
then the curves will be rendered more smoothly in the 3D view:
Will,
I’ll try again.
Thanks
The circle renders smoothly in 3D.
I’m still getting oval-type cut circles on CNC.
Think my Shapeoko XXL needs a minor tuneup: cleaning, belt-tightening, etc. Thanks again for your help.
Have you calibrated for belt-stretch?
