Макрос для формирования карты высот
Редактировал(а) Edgar Allan Poe 2024/11/14 17:01
Для определённых задач (например, фрезеровки печатных плат) может возникнуть необходимость сканирования поверхности с последующей корректировкой неровностей по Z.
Карту высот на основе сканирования поверхности можно подготовить с помощью макроса (пример ниже) и затем, используя эту карту высот, модифицировать G-код.
Сформировать G-код с готовыми координатами поможет, например, программа G-Code Ripper.
