+ | ====== Precise Kerf Compensation in Inkscape ====== | ||
+ | The " | ||
+ | |||
+ | Here's how to take any inkscape drawing and compensate for the kerf, such that the resulting cut shape is closer to the intended dimensions. | ||
+ | |||
+ | Measure material thickness before drawing! If material is 5.6 mm and you draw assuming 6 mm, you still wont get tight fits. | ||
+ | |||
+ | - Recommended: | ||
+ | - Select all paths you want to modify (Ctrl+A) | ||
+ | - Set **Stroke Width** to **0.3 mm** (typical lasersaur kerf/cut width) (Ctrl+Shift+F > Stroke Style > Width) | ||
+ | - Convert **Stroke to Path** (Path > Stroke to Path). This will create a narrow filled area where the path was. | ||
+ | - **Break apart** the result (Path > Break Apart). This will separate the inner and outer path. They are now both completely filled areas. | ||
+ | - To see them as two individual paths, set *Fill None*, *Stroke Solid Black*. You now have two paths for each shape. | ||
+ | - Remove inner path or outer path depending on whether it's a shape or hole | ||
+ | |||
+ | The resulting line will be exactly 0.15 mm offset from the original line, so that the kerf (having 0.3 mm diameter) should cut right up to the original path. |
