The card reader on my old display wore out so I replaced it with a new one I had left over from an old Primo build.
It is working fine in Marlin mode with my mini rambo on my LR2 but the knob rotation is backwards from the old display and I’m scared i’m going to ram the z into my table from years of muscle memory. I went through the configuration menu on the display and couldn’t find any way to change it. Is this an easy fix?
You have to change a firmware setting, compile, and flash the firmware. I believe this is setting you need. It is in configuration.h:
//
// This option reverses the encoder direction everywhere.
//
// Set this option if CLOCKWISE causes values to DECREASE
//
#define REVERSE_ENCODER_DIRECTION
You need to either uncomment or comment the define to reverse the logic.
