Hello all,
Yesterday was the first day that I linked my printer to the computer and I was able to move all of the axis's with no trouble. I did however flip the orientation of the extruder motor because it was pushing the filament out-not in. Everything was working well until today when I tried to turn it back on - the ramps board now only blinks twice at LED 1 upon plugging it in- LED's 3-4 do not respond to the power. Now I have been unable to connect the printer to pronterface as I am receiving an indefinite "connecting" response. I tried connecting with repetier and am receiving an error message stating "COM5 access denied". I have checked all connections several times and have run into a major roadblock, any help would be much appreciated. I initially followed reprap wikis instructions and am using Marlin. Thanks.
