I've read elsewhere on this forum where it is advised to look ahead and not directly at the burr when cutting straight lines. How far ahead do you generally look? Are we talking about a millimeter, two millimeters, more? Do you shift your focus between the point where the burr is lifting and your focus spot on the scribed line ahead of the cut? Or do you keep your focus on the forward looking spot and just keep the burr in your peripheral vision? Appreciate your feedback.
