3.1 | 1 | Для определённых задач (например, фрезеровки печатных плат) возникает необходимость сканирования поверхности с последующей корректировкой неровностей по Z. Карта высот подготавливается с помощью макроса (пример ниже), и на основе этой карты высот модифицируется G-код. Сформировать G-код с готовыми координатами можно, например, в программе G-Code Ripper. |
