I think the only time I ever overloaded my lowrider was when I was surfacing the spoil board. Like Jeff said, it’s not always level, and boards are never perfectly flat. That was also a 1" surfacing bit though. My video I posted was a quarter inch endmill. No skipped steps, and the measurements were pretty close to spot on.
This is maple butcher block with a quarter inch depth of cut and a quarter inch endmill. I’m not sure if I still have the gcode for it, not sure the speeds and feeds I used.
Found it. Was cutting at 15mm/s.
