What happens here

The speaker identifies the 3x4 sander as a direct drive type. This means the sanding pad orbits in a consistent, non-random circular pattern. This action is precise and uniform, making it suitable for specific tasks where a consistent motion is beneficial, such as achieving a fine finish on specific edges or in tighter areas, and it does not produce a random sanding pattern.

Goal: Comprehend the operating principle and typical application of a direct drive sander in DIY.

The 3-Bot 4 is a direct drive, so that means it's orbiting, but it's orbiting in a circle. No random pattern. These two are random argo, the 5-inch and the 6-inch are random argo, so you have a much wider swath and you have that rotation and that random pattern.
