<p>I´ve tried tunning printer settings with different Nozzle(190-210&nbsp;ºC)/ Bed(0-60&nbsp;ºC) Temperatures, Fan Speeds (0-100&nbsp;%), Cura and Slicer adjustemens but nothing worked. I still get the same bubbles in the first 3&nbsp;mm of every print. 
I also tried a glass bed and the magnetic bed that comes with Ender 3 pro and the result is still the same.
The last thing I tried was moving the 0 position of the Z axis 10&nbsp;mm up, but it didn´work.</p>

<p>What else could I try? Any idea of which could be the issue. Thanks in advance.</p>
