Encoder wheel/button @ Paneldue



  • I wonder if it would be a good idea to add an encoder button to our machines.
    I changed from marlin to reprap and the only thing i really miss is the encoder wheel.
    I normally used it for baby stepping to get my first layer right.

    Is there a chance to get something like this added to my duet wifi?
    I dont like the touch option for stepping because i always have to check the screen to get the button hit right and in parallel the first layer.

    Maybe we can get it connected to the extension header somehow and route the pins to stepping.

    With best regards

  • dc42 has previously said paneldue has pins for this, but lacks firmware support.

  • Thanks,

    will have a look. Would be great if something would be coming.

  • So if i understood it right we got three inputs on the paneldue X4.
    Are these inputs routed in the software somehow?
    Does anybody know where i can find the pin names or documentation for theese i/o's

    Thanks

    afaik, no. Will have to be handled in PanelDue firmware i think.

    The latest PanelDue firmware source does have a driver for the encoder interface, however currently it just feeds test code that generates G1 commands to move the X axis. It needs to be changed to be context-sensitive.



  • I'll give it a go and have a closer look.

    Thanks for the guidance

  • Hi,
    just wanted to "vote 1 up", that in my opinion especially for something like the entry-board like the maestro, an entry level priced minimal-interface like those little (non touch-) screens with an encoder wheel would be a nice companion!
    (The other folks that spend more for a bigger/better motherboard, for sure have resources to have one of the bigger touch-screens (I like the 7" most, for touch I think bigger is better, especially if you have thick fingers and are a nervous person).)
    So I think this idea has potential...

    The Maestro already supports 12864-style displays with encoder using the ST7920 controller chip.
