it's a bit late now, but I would have made a test run before the final cut, with 0.005" stock to leave , measured that it's leaving the 0.005" and then cut based on the outcome of the measurement. This comes up very often when I have to make holes for calendar inserts in molds. for a hole of D6-8 mm and depth f 12 mm if I leave .01 mm even if I hammer the insert in it wont go down all the way. Overcut it by 0.005 mm and it falls out. So i make a test cut with a step of 0.005 mm and measure it as the hole grows. I usually get it down to 3-4 cuts altogether. Gracjan PS . I suspect your tool was not in the center , or you had a chip between the tool and the spindle. I just had a case like that a few months ago. No simulation will help here.

I ran the benchmark 3.0 on my home machine , a 4,00 GHz i7 on all the mcams I have installed: 2019 4:54 2020 4:18 2021 4:06 2022 4:21 the 2022 was a bumpy ride . Gracjan

If you have the "Auto-cursor" options enabled, you can press the letter of the keyboard shortcut for the "Auto Cursor Override" options. This means to snap to an Arc Center, you press the letter "C" on the keyboard. "M" for Midpoint, "E" for Endpoint, "O" for Origin, "I" for Intersection, "P" for Point, and so on. There is a lot of time to be gained from using these shortcuts.

I have that problem on my laptop. Go to screen resolution, and change it to "Landscape". Then try to hit the OK button before it reverts back.
