I created a 2D contour to cut at 28 in/min and noticed that my Shapeoko 3 was cutting at 10 in/min.

The same project includes a pocket cut, also set to 28 in/min and it actually cuts at the correct speed.

I know almost nothing about g-code but it looks like the job starts at 25 in/min and then switches to 10 in/min.

Am I setting something wrong in F360?

Here’s a piece of the G-code:
