Configuración CURA para Prusa i3 y extrusor Budas
#1
Hola!
Pues ya tengo funcionando con el hotend de 0,5 mi máquina y para no dar palos de ciego me gustaría que me dijeseis que parámetros son los adecuados para usar el Cura.

- En diámetro de filamento tenía 2.85 mm, pero me han recomendado poner 2,95 ¿es correcto?
- La velocidad de impresión tengo por defecto 50mm/s, ¿Es recomendable bajarla? ¿cuanto?
- ¿Cuanta cantidad de retracción soléis poner? ¿Velocidad la de por defecto verdad?
- Si pongo el hotend de 0,4 para hacer alturas de capa de 0,2 o 0,3, ¿Que parámetros de impresión me recomendáis cambiar?

En fin, cualquier ayuda será bienvenida, ¡Gracias!

¿Que diametro de filamento tienes? De todas formas no entiendo porque poner un diametro de filamento diferente del real. Puedes ajustar la cantidad de material con el parametro flow. Yo lo tengo a 180% y va de lujo.

La velocidad de impresion de 50 es poco, yo lo tengo a 70.

Para el resto de parametros, te pego mi configuracion. Es para un filamento de 1,75.
