| Problemas con la impresión Slicer3r |

Buenas os cuento mi problema.
Estoy imprimiendo una pieza que tiene dos milímetros de grosor (una especie de tapón para haceros una idea), y material ABS.
Utilizando el simplify me ocurre siempre que las piezas de grosor fino no me las termina de cerrar y me deja ciertos huecos libres (no se solucionarlo).
He probado a utlizar el slicer3r, ya lo habia probado alguna vez que otra, pero esta vez me ocurre que cuando va incrementando la capa hecha el material fuera, osea como si subiera el eje z sin hechar material, y ocurre al principio de la impresión. Lo mismo me ocurre con el Cura.
He limpiado el cabezal, le reemplaze el pololus por si tenia algun problema y tampoco. He probado varias impresiones y pasa lo mismo.
Deciros que con la misma configuración ya habia imprimido anteriormente correctamente.
Es posible que haya habido algo raro en el firmware arduino y deba instalarlo de nuevo, es lo que se me ocurreo. Porque por lo demás no ha pasado nada y solo me ocurre con Slicer3r y Cura, con Simplify3d no, pero tengo problemas.
Gracias.

Buenas gente!!
Pues estoy mirando de pasar mi prusa i3 a dual extruder, dado que necesito hacer unas piezas algo complejitas y me gustaria usar el segundo extrusor para imprimir soportes en PVA.
Actualmente tengo un Jhead, que necesitaria para pasarla a dual extruder? a parte de otro nema17 y otro jhed. O me recomendais otro hot end?
saludos!

Hola a todos. He montado el sensor inductivo para hacer autolevel y me encuentro que cuando lo activo en marlin al hacer home a todos los ejes desde la pantalla lcd o desde el pc.
Me dice que los ejes X:91.0 Y:79.0 Z:0 en vez de X:0 Y:0 Z:0 en el lcd. y claro no me hace el autolevel....
os pongo mi configuracion de marlin.

Alguien sabe que puede ocurrir porque en todos los tutoriales que encuentro solo hay que descomentar #define AUTO_BED_LEVELING_FEATURE , ajustar el offset del sensor respecto del nozzle que en mi caso son Y 21 mm detras del nozzle X en linea y cambiar la logica del endstop z min a true.
El signal del sensor lo tengo conectado donde el endstop zmin signal
UN saludo.

entonces me surgen dos dudas:
