3D-Drucker/Slic3r

Derzeitige Probleme mit Slir3r

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

Skripte rund um Slic3r

Scrkit um Slic3r, Config, stl und gcode zusammenzuhalten 3D-Drucker/Slic3r/create.
eignen G-Code erstellen, der die Konfigurationen von Slic3r benutzt 3D-Drucker/Slic3r/Python.

Old

maximale Z-Achsen Geschwidigkeit

Wird nicht mehr benötigt, weil die Schrittmotoren der z-Achse einzelne [[3D-Drucker/PoliluDriverA4988|Treiber] haben.

Patch für Slic3r

Mein patch für Slic3r, damit Sli3r eine maximale z-Geschwindigkeit hat.
