Problem with LCD wheel.

[Mensopelaez]

Hi, I mounted my I3 pro w a few days ago. I've got a problem. It allows the printer do its job, but it's a problem for me.
The wheel that controls feed rate, turns in reverse as it should. So to reduce feed rate you have to turn it in clock direction. Same when you move axis or move between the menus.

Any idea how to solve it?

Thanks in advance.

Hello.


You mean the incremental pulser (encoder) for operating the printer menu.
I have already noticed this in the case of my printer.
In order to improve this, it is necessary to modify the firmware.
This is not a big problem, but nobody has corrected it.

You can report the problem to Geeetech Github.

Yes, that's what I mean.
But couldn't find the way to do it in the firmware. (I'm new at this)
Looked at some ways to do it in the net but it didnt work.

if you are using marlin 1.1.8
under the config tab in marlin, u need to scroll down to line 1388 until u see this

Code: Select all

// This option reverses the encoder direction everywhere.
//
//  Set this option if CLOCKWISE causes values to DECREASE
//
//#define REVERSE_ENCODER_DIRECTION

//
// This option reverses the encoder direction for navigating LCD menus.
//
//  If CLOCKWISE normally moves DOWN this makes it go UP.
//  If CLOCKWISE normally moves UP this makes it go DOWN.
//
#define REVERSE_MENU_DIRECTION

either take out or put in // before the #define to suit your needs.
