MakerFarm Pegasus 8' Printer Problem

[DreaMPoweR]

Hi, I use MakerFarm Pegasus 8' printer: http://www.makerfarm.com/index.php/pegasus-8-kit.html

I have been getting some melting or filament (1.75 mm PLA RoHS) issues with my 3D printed parts. The spaces are coming together. I changed the temperature of the extruder and changed a couple of different parameters but they did not solve my problem. I attached the pictures of the parts. Hope somebody can help.

Thanks.

Perimeters: 2
Shells: 3, 3 (bottom and top)
