Hi have just set up a mega with a 2 differant ramps 1.6 boards and the 20x4 reprap controller. I have succesfully loaded the firmware on . all the parts have been used and I know there working no mpg encoder connected or keypad. The lcd backlight comes on and the steppers lock. Any Ideas regards Tony

Steppers locking is normal, type '$SLP' into serial monitor to see them unlock.

LCD not working means pinout definitions for your setup are not correct. Change them.

I haven't modified any code , I have noticed occasionally when I plug it in it comes up with garbage on the screen, a missmash of letters and figures Regards Tony

ok I wound it up to 15 vols and it works now?? I can bring it down to 12v and its still OK, Ive put a keypad on it but its a bit buggy. for instance how do you jog an axis? However I can pick up a file and run it from the sd card, plus I can communicate with it from pronterface. regards Tony
