One of the biggest battles I fought early on with my 12" printer was inconsistent Z axis homing, I would have to mess with it sometimes 4 or 5 times before I could get a good first layer on a print. Looking back on it now the Z homing issues I experienced were due to the print bed physically moving during the heat cycle. This was caused by the wooden Y bed itself warping and by the heat bed surface warping up and down as the heat relay turned on and off.

As has been mentioned your first layer needs to be flat and stuck down well, without that good first layer the rest of your print will suffer.
Been awhile since I posted. I have printed so many cool things. I love this thing, however I am fighting a few issues but the main one is the z axis homing as mentioned above. It's driving me nuts every time I go to print its at a different hight. I would like to upgrade to an automatic leveling or figure a way to fix. I am pretty sure its a number of things. The end stop probably the main issue being it has some play in it. I need to put a new zip tie or redesign it altogether.
