Hy
I try some hour for configure it on repetier but not work
On the web i see
Define feature controler 2
Not work for me
I try to modify uiconfig but the same

On marlin i define REPRAP_DISCOUNT_SMART_CONTROLLER
And use a liquide cristal librarie
And work fine

What is the setup for this screen please, this my last setup for my printer.
Thanks

    We also have a reprapdiscount controller to select. But that does not use I2C so it will not work and I wonder why it should work then with marlin. I2C is always slow and hard to setup. The viki display uses it so you could check how it is done there but you definitely need to do in manually in uiconfig and set the controller to use it.
