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.
