Printing off the bed when sliced

I'm new to 3d printing, very new. I bought a folger tech 2020 prusa i3 and successfully built it. I connected it to my computer, downloaded repetier with slic3r and have run into so many issues. At first the extruder was pushing the filament outwards, I flipped the cables on the board, and that was fixed. But now my issue is that my prints are not being centered. I center them on repetier, but when I slice it, it is moved over to the right most of the bed. And then I try to move it but I can't. I have read about fixing this by editing g-code, but I don't know how to do that. I have just been using the settings on the program itself. Now, at first I thought it was my printer but I am almost sure that its a setting on the actual program that makes it thing that the center is on the right side of the bed but only after it is sliced. It makes no sense. Please help, and I apologize for my ignorance.

I also wanted to add that my solution has been (so far) to place the object to the left most of the bed, then slice it, which places the object around the center of the bed, but then the printer printer prints it on the right side (some hangs off)... my X endstop is located so that it is activated when the nozzle is directly over one mm off of the right of the bed.

I think it may be that your endstops are connected to the wrong set of pins on your ramps board. I gave some trouble shooting solutions to someone who had the same problem on This thread. Check it out and see if it helps

i appreciate your reply but:

1) I followed a guide and the guide told me the order and they said the cables had to be in the order of red black and green (top to bottom) and If I flipped them I could cause perm damage. I haven't tried changing the order of the three though.

2) How would improper endstop plugin cause the slicer program to move the file after slicing (before printing)

I made sure all wires were correct. Homing on xy and z axis are perfect. I click each and extruder moves till it touches endstop. My issue continues to be with the slicer itself: when I slice, object is shifted and partially out of printing area.
