I'm going through the same things right now with the Delta G2s printer I'm putting together. I still have not printed anything. Instead, I've been modifying the firmware.

I've made several changes to make it easier to bring up Delta printers. First, I've added a bed leveling command for 3 support point beds with a primary focus on Delta's. It lets you get the bed very close to level in spite of the dish effect. I've also made some changes so when traveling large horizontal distances the nozzle does not dip any more. (During bed leveling and such I was having problems with the nozzle dipping and scrapping the bed.)
