Ramps 1.4

sufii

I accidentally connected the end stopper of auto level at the place of z end stopper and z end stopper at 7th pair of pins of Ramps, my ramps is not working, it is not giving power supply to the motors, but its lights are on, can anybody please figure it out?

this has happened to me twice, what happens is that issue burns the voltage regulator on your Arduino , you can replace it  or you have to buy another Arduino board. 

  

Read hear about that Issue

Three times for me, 1 of them a Rumba.

My power supply is 12V @ 30Amps,   no mercy unfortunately.

I've seen some funny things on my graphic display..
