3D-Drucker/Slic3r
Es gibt nun ein Script damit immer klar ist, mit welcher Slic3r Version und Config ein gcode erzeugt wurde 3D-Drucker/Slic3r/create.
Derzeitige Probleme mit Slir3r
- Slic3r so stark in Entwicklung, das Config abhängig von git Version ist

Old
maximale Z-Achsen Geschwidigkeit
Wird nicht mehr benötigt, weil die Schrittmotoren der z-Achse einzeln angestuert werden.
Patch für Slic3r
Mein patch für Slic3r, damit Sli3r eine maximale z-Geschwindigkeit hat.
