<p>I have a problem with large lines in the first layer of my prints which have curvatures. The last layer has no problems. You can see the problem in the horizontal line of the "A", the rest of the "A" seems fine. Here are example pictures:</p>

<p>What can that be?</p>

Level your bed properly... What is the first layer height? its speed and flow of first layer?

This looks like too much material for the room available; have you tried decreasing your flow maybe 5%?
