have a smoothie on strip board, firmware update works, attached lcd using universal adapter. Also attached 4 buttons and mapped them to click, back, up, down. Buttons are NO with pull down resistors, when pressed they get 5v. when released 0v. On applying power i get "Smoothie ready" screen, but pressing any of the buttons does not effect the screen. i want to go to the jog screen and move the axis. limit is disabled.
What needs to be done to get to jog screen with buttons.
