For a while I'm working on my Kossel mini and I'm now at the stage where I can connect and test the electronics. Today I tried to connect the LCD but I had no luck with it. When I connect the power to the Ramps board the LCD flashes one time and then nothing hapens. Within the the second it lids up there is no information shown.
What I tried to solve the issue is:
modifying Pin.h => #define RAMPS_V_1_3 (uncommented) (rule:390)
modifying Configuration.h => #define REPRAP_DISCOUNT_SMART_CONTROLLER (uncommented) (rule: 526)
modifying Configuration.h => #define SDSUPPORT // Enable SD Card Support in Hardware Console (uncommented) (rule: 511)
modifying Marlin => added #include (It also shows in the library folder)
I used the Marlin files that are on Johanns github page.
Solved: removing the stepper motor controllers made the display work.

Furthermore I was wondering if I need to connect the motors when powering the Ramps board. I'm a bit afraid that a motor will start running so I prefer to have it disconnected while I'm figuring out some stuff.

Also I can't upload the program to the arduino with the ramps attached (not enough power?). Is this normal? Removing the ramps board from the arduino board is a pain in the ass because it is very easy to bend pins.

The rotary encoder doesn't work. Clicking works and so does the beeper. I checked the pinning in Pin.h and it appears to be correct. I also tried to fiddle a bit with the "//#define ENCODER_PULSES_PER_STEP 1 // Increase if you have a high resolution encoder" value after uncommenting it.
Please let me know if you have suggestions. Thanks in advance.
