I wrote this almost a year ago. I can't remember for sure how marlin 1.1 was different. I think the software lets you keep your button z-stop and also install a prox sensor for auto leveling. This 1.0 tutorial removes the z-stop and uses the prox sensor for auto leveling and stop sensing. The bigger issue with upgrading to 1.1 is that the LCD touch panel won't work.
Send gcode command M503 and take a look at your Maximum feedrates (mm/s).I never push my printer faster than 60mm/s in my slicer settings so I have:M203 X60.00 Y60.00This should cap max speed and prevent the fast movement you're seeing. Don't forget to send M500 command to save your new settings.
Setting offsets was always a headache. I got so tired of it that I actually rolled back to the original firmware and re-installed my adjustable z-stop. I still use the prox. sensor to manually level the bed using the light indicator then I adjust the z-offset with the set screw.
Yea. Updating the LCD firmware might be needed. Here are instructions on how to update the firmware. When I setup the SD card I had to format it and copy the files using only linux. Otherwise the lcd doesn't recognize the card. http://www.wanhao3dprinter.com/FAQ/ShowArticle.asp...
The z-probe connector is connected to an atmega pin but was never setup in the firmware to be used. It might have been useful with Marlin-RC but they went with Marlin 1.0.x and didn't populate the connector for whatever reason.

It wouldn't compile with the newer IDE. Maybe I did something wrong but from experience I know to try the older IDE if something won't compile in the newer.
