Excessive speed on flat areas problem

When previewing animations of carve setups, I am seeing “teleporting” of toolpaths over flat areas: that is, extremely fast motion over flat areas that are sure to break bits and damage stock. Are these animations accurate?

If so, how do I set up toolpaths to progress at a consistent speed? I have tried many available options to address this issue, but to no avail. I am using a 1/4 roughing pass, with a 1/16 ball contour pass, and both still have this aberrant behavior. In the limits sidebar, XY speed is 6000, & I have increased Z speed to 3000, but the problem remains.
What am I doing wrong?

The animations are not real-time accurate. If you’re still nervous, you can enable “Force Z Max” and all moves will lift to a point over the highest Z first.

Thanks for your advice & timely reply! Ill give it a go

The animation remained the same as before with Force Z Max enabled. However, the test run on the CNC showed that the toolpaths followed without acceleration on flat areas, running a file that was generated before I enabled Force Z Max.
