For me, both the X and Y axis movements were reversed in Pronterface and Repetier-Host. I eventually got annoyed by it and swapped the motor directions (by rotating the motor plugs on RAMPS by 180 degrees) and by moving the endstop switch locations to the opposite ends of the travel. I'm pretty sure you can deal with all this in firmware changes, but I wasn't ready to jump into modifying the firmware at the time.

I've had the hex hot end fan pulling air from day one. It helps with ABS prints by reducing airflow pushing down on the print below the extruder.

Thanks Printbus and Gmay3. I will leave it as it is for now until it annoys me. I am pretty much planning on only doing ABS, so sounds like it should be fine.

I just need to figure out what is binding on the right side, get some more wire for the heat bed and I will be about ready to do a test print!!!!

This is good to know! I will be switching mine ASAP.

Well, it is sort of a mixed bag. I noticed more airflow on the forward side of the heat bed with the fan reversed. On the few large ABS prints I've done, I added a piece of tape to the bottom of the fan, shaping it upwards a bit to help keep the draft off the bed.
