Utilizo un micro-pulsador. Al bajar el brazo , toca el pulsador con la cama. El sistema esta compuesto por un micro-pulsador, servo,1 resistencia y un led , más las piezas de plástico impresas.
Jadc me gusta tu montaje.
Tengo un sensor capacitivo, he hecho un divisor resistivo para adaptar la señal del sensor a la entrada de la ramps.
Las resistencias que utilizado son de 10k y 15k, con esto obtengo una tensión de unos 4,5v aproximadamente si no recuerdo mal.
He conectado este circuito al sensor y tengo 3,5v a la salida.
Puede ser que haya tanta caída de tensión por la longitud del cable?
Serán suficientes los 3,5 v para que arduino detecte un nivel alto?
Muy buenas, por favor, ayudadme, el LED del sensor n ose apaga nunca aunque le pase la mano por delante o lo que sea, le he dado al potenciómetro en ambos sentidos como para atornillar un tornillo de 50mm y no se apaga el led el montaje supongo que está bien hecho y ya no se qué hacer :S Ayuda por favor!

Si ya lo he visto. Pero ya lo tengo hecho. Funcionar funciona detecta bien y cae la tension a 0,5 V aprox.
Me falta configurar el marlin para adaptar el sensor, seguire tu tutorial fmalpartida.
( por cierto todos tus tutoriales son geniales y muy bien explicados).
Me autocito. Puedo confirmar que este montaje funciona. El objetivo era que fuera lo más sencillo posible y lo más compatible, en el sentido de tener que cambiar la configuración de Marlin lo mínimo con respecto a un montaje normal con endstop mecánico.
El setup es el siguiente:
Pullup del endstop del eje Z ACTIVADO
Invertir endstop eje Z DESACTIVADO
Sensor capacitivo/inductivo NPN
Se usa únicamente el optoacoplador y una resistencia. Opcionalmente se deja como backup el endstop mecánico en serie, en modo NC (si no se usa hay que puentear el jumper del esquema). Al estar en modo NC (normally connected), si falla alguna conexión la impresora no se movería (estaría el endstop en modo TRIGGERED), siendo esto mucho más seguro que el modo NO (normally open).
Por cierto, mi felicitación al maker al que se le ocurriera lo del optoacoplador, realmente es una gran idea. Y lo mismo digo para el que se lo ocurriera lo del sensor capacitivo/inductivo, sin duda un gran avance en este mundillo
Adjunto los esquemas. La PCB está pensada para poder hacerse en una protoboard y enchufarla directamente en la ramps. No pongo la alimentación de 12v al sensor por un motivo: normalmente ya tenemos un par de cables con 12v en el extrusor para alimentar el ventilador del hotend, por lo que se puede reutilizar esta conexión para alimentar el sensor. Por ello hasta la ramps únicamente es necesario que llegue el cable "signal".
Saludos!

Perdón por citar un post de tan atrás en el hilo, pero estoy montando esta variante y me surge una duda... ¿para qué la resistencia de 10k si ya la ramps cuenta con un pullup interno?
Edito: y siguiendo el razonamiento, si ya tenemos internamente una conexión de + a Signal con pullup, ¿para qué tenemos que conectar el + al opto? ¿no valdría con conectar simplemente el Signal como si de un microswitch mecánico normal se tratara?

donde se pueden encontrar estas piezas y algun esquema básico de montaje? no encuentro nada ni similar por thingiverse...
la parte del fin de carrera mecanico parece funcionar bien y detiene el eje Z.
La parte del sensor capacitivo, el sensor conectado se ilumina el led y cuando le pones algo en frente se ilumina mas fuerte.
pero no detiene el eje Z.
Me equivoqe al poner la resistencia de 4,7k ohm y puse de 470ohm. ¿me puedo haber cargado el optoacoplador?
¿como puedo comprobarlo? ¿alguna otra comprobacion que pueda realizar?
Otra pregunta..haciendo pruebas y utlizando un ENDSTOP de tres pines de los que van en placa con su led y todo, haciendo pruebas independientes del circutio electronico, he visto que no funciona, que no me registra señal en el arduino si le quito el cable central, el negativo o NO(normally Open). No se si es culpa de la placa del endstop,....
¿Alquien con los mismos problemas?
¿Alguna solucion?
Quiero instalar el sensor capacitivo pero manteniendo ese endstop, ¿es posible.?
A ver si me podéis echar una manita porque por fin me he puesto a montar el autolevel pero tengo algún problemilla y ya me tiene loco.
La parte mecánica y electrónica creo que la tengo más o menos bien. Los finales de carrera se detectan bien pero parece que los comandos G28 y G29 se pierden un poco en las coordenadas...
Ya le he puesto el offset del sensor al nozle mediante m851 z-2.8 y aparentemente lo pilla bien.
Cuando hago el G28 hace el homing de X e Y y luego el nozle se va a X40 Y100 (que con los 60 que tengo de offset X del sensor al nozle, pone el sensor el X100,Y100) y hace el homing de Z. Tras hacer los tres homings, el nozle se queda en X40, Y100, Z2.8 a la espera del siguiente comando.
Ahora hago el G29 para el autolevel y aquí es donde empieza el problema:
- Empieza justo donde acabó el G28 (X40, Y100, Z2.8)
- Hace las pruebas donde le parece (mucho más cerca de los extremos de la cama que donde le digo, que es (LEFT_PROBE_BED_POSITION 10, RIGHT_PROBE_BED_POSITION 140, BACK_PROBE_BED_POSITION 140, FRONT_PROBE_BED_POSITION 10)
- Cuando termina el nozle está casi atras a la derecha y las coordenadas las ha perdido completamente por el camino. Este es el resultado del comando M114: X:-40.04 Y:149.97 Z:1.72 E:0.00 Count X: -40.04 Y:149.98 Z:0.76
¿Por qué narices me pierde las coordenadas? :-(
He probado con varios Marlin (la versión antigua que tenía instalada antes de instalar el autolevel, la 1.02 y la 1.03 developer).
He probado con Repetier-Host, que es el que utilizaba habitualmente, y viendo que no lo conseguía he instalado y probado también con Pronterface.

/*================== Thermal Runaway Protection ==============================
This is a feature to protect your printer from burn up in flames if it has
a thermistor coming off place (this happened to a friend of mine recently and
motivated me writing this feature).
The issue: If a thermistor come off, it will read a lower temperature than actual.
The system will turn the heater on forever, burning up the filament and anything
else around.
After the temperature reaches the target for the first time, this feature will
start measuring for how long the current temperature stays below the target
minus _HYSTERESIS (set_temperature - THERMAL_RUNAWAY_PROTECTION_HYSTERESIS).
If it stays longer than _PERIOD, it means the thermistor temperature
cannot catch up with the target, so something *may be* wrong. Then, to be on the
safe side, the system will he halt.
Bear in mind the count down will just start AFTER the first time the
thermistor temperature is over the target, so you will have no problem if
your extruder heater takes 2 minutes to hit the target on heating.

Comentar que yo tengo el kit de la conjunta del sensor, y funciona perfectamente ... salvo algunas cosillas que poco a poco vamos sacando.
Para el que le interese, hay algún comentario en clonewars que podría interesarle (link).
Creo que a mí me pasó como lo que comentas. La solución en mi caso para el G28 fué dividir el homming en dos instrucciones
G28 X0 Y0
G28 Z0
Y luego el G29 ya lo hace desde el punto 0,0 (el homming de Z me es necesario si la figura anterior hubiera dejado el carro en Z muy alto, no le gusta al hacer un G29 después del X0 Y0).
Espero que te vaya bien, saludos
La impresión 3D casera no es una ciencia exacta: a las mismas entradas y ejecutando el mismo proceso, no siempre sale el mismo resultado .... para desconsuelo de los que sólo queremos conseguir imprimir en 3D :(

Bueno, finalmente he descargado un Marlin preconfigurado que dejó alguien en un dropbox y ha funcionado a la primera. No tengo ni idea de por qué las versiones "oficiales" dan tantos problemas.
La verdad es que funciona estupendamente. La impresora es otra con el sensor :-)

hola buenas a todos me leido todo el post desde la pagina 1 a la 18 y no he podido resolver mi problema, me echo con un senor capacitativo y el sensor me va cuando paso la mano hace de final de carrera hasta entonces todo bien el problema es el endstop mecanico quiero conservarlo, lo tenia todos conectados en comun y nc por lo tanto cuando lo conectaba en la pcb no me iba ni el sensor ni el endstop, si quito el endstop va todo bien, echo otro endstop en nc y no. lo conecto y va el sensor pero el endstop no va... que puedo hacer no se me ocurre nada
