"backwards" scrolling with LCD 12864 Graphic Smart Display

bkey1970 · August 2019

I'm restoring my 3d Printer after a major failure of the melzi board, and am converting to RAMPS. It's going smoothly, except for what I see as backwards scrolling on the display. If I use the display input menus, I have to turn the knob left for going down, and right for going up. Is there a way to reverse this, to match the operation of the previous board?

Thanks!

in configuration.h look for :

#define UI_REVERSE_ENCODER 0

if 0 change to 1 or if 1 change to 0

that should fix the issue

Perfect. For this kit, it's 1.

Thank you.

FWIW, if anyone else sees this, and wonders the kit here is what I'm using.
