monoprice mini v2 - won't start printing some models

[WCOkeefe 0]

i can successfully print a bed leveling test. i have successfully printed some stl files. any file i slice from an obj file fails to even start printing. some stl files fail to start, some start fine. i am using the same slicing settings.

 

help please.

I believe I got this one solved as well. Now I am having bed adhesion problems. My leveling tests have come out fine, but actual prints are having issues.  Trying different brim/raft settings.  It always fails in the same spots so I am thinking I am just a fraction off of a good level as well.
