[FILAMENT_SENSOR in Tinkergnome]

@Tinkergnome & Novastorm

Thank you :-D

I see, my NC-switch (that I already have) will do quite nicely.

(since it will be triggered, when filament is present = open)

You helped a lot, I'm going to try it out, as soon as I designed myself a mount for my bearing and switch.

Danke ihr Beiden, sehe gerade, dass ihr auch aus Deutschland kommt ;-)
Ihr habt mir echt geholfen

[FILAMENT_SENSOR in Tinkergnome]

Afaik all is explained in detail in this link

Also ofc you will need Tinkergnome firmware to make it work

 

Thank you for your reply, I've already seen the Topic on the Forum.

The "Instructions" are not that detailed. They are using a sensor called "Tunnel", which does a little bit more than detect outage of Filament. It also detects filament movement, it's connected to J23, which consists of 3 Pins(PC7, +5V, GND).

So can I even connect a mechanical switch without electronics? Do i need an NO-Switch instead of my NC? Do I need something fancy like a Drop-Down-Resistor(like this)

Sadly, i still don't understand how to realise that function.

[FILAMENT_SENSOR in Tinkergnome]

Hi everyone,

good evening

 

I've been printing with my trusty UM2 for a while now, but there's something that i'm missing.

 

A sensor that pauses my Print and lets me change the Filament, when it runs out.

I want to use a mechanical NC-Endstop-Switch (normally closed) and later on, i might switch to an optical Sensor, depending on how well the mechanical one does.

 

 

I don't want to use Octoprint(for now). And Tinkergnome seems to support it.

See:

...community/17860-ultimaker2marlin-and-filament-runout-sensor

Part of Pins.h in Tinkergnome 16.08.2:

 

 #ifndef FILAMENT_SENSOR_PIN#define FILAMENT_SENSOR_PIN         -1  // PC7 = D30; PD7 = D38#endif

 

Is there some guide on how to connect my switch to the UM2-Board and how to activate it in the Firmware?

 

At the moment I'm still using the original UM2-Marlin.

 

Thank you very much.

 

Greetings
