How can i connect a rotary encoder to my RAMPS 1.4 with a Marlin firmware February 22, 2019 09:57AM |

Hey Guys,
i have a little problem and on google i didn´t find some help.
My setup is a Arduino Mega with a Ramps 1.4 motherboard. I have connected a 16x4 LCD Panel with I2C. That all works fine.
But i have big problems to get the rotary encoder to work. I have tried several settings in the Configuration.h and the pins_Ramps.h but nothing works.
Any help here would be greatly appreciated!
My Specs:
Arduino Mega
Ramps 1.4
Marlin 1.1.9
Rotary encoder (Pins: CLK, DT, SW, +, GND)

The LCD rotary encoder pins are different depending on which display you have set Marlin to use.
Which LCD display have you set in your config file ? .. which ever that is that works for your LCD.
Maybe post your Configuration.h file here for us to see ?

Nothing in that section ..
is compiled for your display settings. Try moving your 3 added lines to be like this .. BEFORE the #if ENABLED(NEWPANEL) line
..

Yes very likely, I'm not yet familiar enough with the marlin code to know all the in's and out's.
Their is a thread here that might help ..

Just checking but you do know the encoder is also a switch?
you can push it in as well as rotate it.
BTN_ENC is the switch pin
BTN_EN1 and BTN_EN2 are the two pins for the quadrature encoding...
also you have to #define NEWPANEL or it ignores the 3 definied pins.

Yes go with what Dust says, they're more familiar with the code than I.
So remove those 3 button pin lines you added in the pins file and change your line in Configuration.h to ..
Then your 3 encoder pins will be ..
37 (enc 1), 35 (enc 2) and 31 (enc push).

I tested it and it didn´t work.
Also i take a look to this post and changed it for my Ramps but it dont´t work.
I wonder wy it doesn´t work. I have used a common Encoder and LCD?
