Yea Jim I look forward to that comparison of black to white. I'm having strange issues. It dialed my 'Extrusion multiplier' back far enough that the first layers don't touch now so there is too little material flowing but I'm getting globs. I'll do more diagnosing. I am curious how the white prints for you.

I've checked over everything. Belts are tight, machine is sound, extruder good (when I code a 20mm extrusion, I extrude 20.3mm...so that's good). Fans are going and everything looks good. I keep making small tweaks. I'll eventually get it.
