<p>I had problems with print bed adhesion when using white PLA (Arctic White) but no problems when using other colors. So I tried to print three bottom layers with transparent PLA and all other layers with white PLA. I did not change any setting and printed both tries one after another using the same .stl file.</p>
<p>There was some warping of the printed ring too. No problems when using transparent plus white PLA.</p>

<p>Right: white PLA only, left: transparent PLA bottom layers plus white PLA above. View of the bottom sides.</p>
<p>Has anyone experienced similar problems?</p>
