The wiring is correct, I've checked the end stops, The board has power, hotbed and extruder get up to temp, My computer sees the printer, the display flashes but works correctly. Geeetech Acrylic I3 Pro 3d Printer,8mm Acrylic mega 2560 with ramps 1.4, 1.75mm filiment 3mm nossel. I checked the orientation of the step motor drivers and thats correct. I never installed anything backwards and I checked the motors with an LED and they do produce power. Maybe its the firmware? Im running aduino 1.o.1 with marlin firmware. I never got firmware from geeetech. Any thoughts? Motors dont even shake or get warm. I've tried 3 types of firmware and nothing works. The printer even thinks its printing if I send a file but nothing moves. I did send a request for geeetech marlin firmware. Thanks

The open end of the endstop is the top wire of the two. I don't know how to add photos.

The side closest to the threaded bar is the top wire on the first picture. Blue is X, red is Y, black is Z. NC is the top wire

I installed the firmware by dropping the file into arduino 1.0.1 the computer connected the hot bed and extruder heat up the display works but when I try to manually move the stepmotors they dont move but the computer reads that they are. Strange

ok I did that and it just goes to the main menu. No movement. On the ramps is a red led constantly on and sometimes a flashing green one.... Mean anything?
