Witam kolegów,

Mimo że swojej grawerki jeszcze nie dokończyłem z przyczyn finansowych, nurtuje mnie sprawa oprogramowania do sterowania cnckiem, oczywiście płyta główna opto-bob i sterowniki m545.

Ma ktoś doświadczenie z czytających kolegów w grawerowaniu ?

Czy z autocada-->mach2 to będzie dobry pomysł?

Jak w autocadzie rozegrać z literami?jakieś tricki,porady?


z góry dzięki za pomoc

poszukuje się fontów liniowych - grawerowanie wychodzi szybciej niż ttfów

ciekawym programikiem do generowania gcodu napisów jest skrypt pod linuxcnc
Text Engraving Software

fajny kod generuje ten skrypt:

pokazany gcode dotyczy implementacji dostępnej w linuxcnc
i robi napis "ALA"

Jeśli chodzi o autoCad to jak dla mnie jest topornym narzędziem do tego typu prac   najlepszym rozwiązaniem do projektowania  literek to Corel
jako tako w machu nie wykonasz  gcodu  to tu jedynie można użyć ArtCam  do naniesienia narzędzia i wygenerowania gcodu
