Fine tuning Z

[ronnien58]

I have set my z offset at .7 as reported by the M114 command after calibrating z home. But when i went to print i had to raise the nozzle using baby steps up .5. Do i need to add or subtract from my z zero that i set in the config. file to print correctly the next time?

I believe it should be subtract to increase gap between nozzle and bed

and add to decrease gap between nozzle and bed
