Filament detector with GT2560 board.

[JohnDeere630]

I bought this filament detector on Amazon: https://www.amazon.com/Dovewill-Filamen ... t+detector
and got it to work on my GT2560 board-controlled I3. The wire from the sensor had to be rearranged on the board end, a 3-pin socket soldered in place of the 2-pin X-max socket, and pin assignments adjusted.......

Update 10/21/18.....
I am now running the latest Marlin firmware, Version 1.1.9, and nothing is changed except the Configuration.h and pins_GT2560_REV_A.h files, which I am attaching.
Below is the diagram I drew up to help keep the connections straight. Note that the socket that the filament detector plugs into, formerly the X-max sensor socket, has been replaced with a 3-pin socket to allow inclusion of the 5V+ pin. The wires coming from the detector had to be rearranged to match the socket.

Thanks for sharing!

No problem. I got sick of baby-sitting long prints and wasting filament when I couldn't. It was an easy process, and has already paid for itself many times over.

Hi JohnDeere630
How did you do that?
What did you change in the pins_ULTIMAKER.h code?
I'd like to know.

Thanks.

Thank you very much.

Asuea,

There were 2 changes needed to the pins_ULTIMAKER.h file:
under the Limit Switches section, change the #define X_MAX_PIN value to #define X_MAX_PIN -1
and under the Misc. Functions, add this line: #define FIL_RUNOUT_PIN 24

This disables the X-max pin assignment, and reassigns pin 24 to the filament runout sensor.

Hope this helps!

Thanks

But I had to make the changes in pin_GT2560_REV_A.h. instead of pins_ULTIMAKER.h. because my 3D printer is a CTC clone and my motherboard is a 2560 REV A

It works!!

Hi there, did your filament switch come with 3 wires and if so how did you wire that up on the GT2560 controller board?

[JohnDeere630]

@ Ikn369330,
I'm sorry I didn't see this earlier; did you get this sorted? I had desolder the 2-pin X-max socket on the motherboard, and solder in a 3-pin socket.

I made up a drawing to label the connectors on the board...

Can someone help me with this.
I didn't find file pins_ULTIMAKER.h but it is pins.h
but still can't find a place where to add #define FIL_RUNOUT_PIN 24
Can someone help me with this?
