Csak RS-274x formátumú gerber fájlokat tudunk elfogadni a gyártáshoz!

Különböző rajzprogramok projekt fájljait nem tudjuk feldolgozni, és nem is tudunk belőle gerber állományokat készíteni ezt mindenki saját maga kell hogy elkészítse.

Mindenki ellenőrizze le hogy a saját tervező programja képes-e ilyen fájlok generálására.

A gerber állományokat tömörített ZIP fáljként kell feltölteni.

A fájlok elkészítése előtt mindenki ellenőriztesse le a saját rajz programjával hogy a gyártási feltételeknek megfelel az elkészült terv.
