This margin extends the range of line widths which follow to [Minimum Wall Line Width - Margin, 2 * Minimum Wall Line Width + Margin]. Increasing this margin reduces the number of transitions, which reduces the number of extrusion starts/stops and travel time. However, large line width variation can lead to under- or overextrusion problems.",
