First layer issue with white PLA

[mvr1127 0]

Hello - first time trying white PLA and keep getting this problem with the first layer.  The raft prints out fine.   This picture is of the object upside down after I took off the raft so you are seeing the underside of the first layer with the second layer showing through the holes.

 

I've recalibrated the z height, leveled the bed, tried varying temperatures between 180-210, various print bed temps between off and 70, and various first layer speeds between 20-40.  Fan has been off whole time.

Don't use raft.  It's an old technology that isn't needed anymore and results in ugliness on the bottom of prints - just like your photo.  Here is much more info about how to get parts to stick to your printbed without using a raft.  why rafts were created (long ago, before PLA filament existed and before heated beds).  Why parts peel up at the corners.  How to keep that from happening.
