Thank you for your response.
To answering your questions:
yes this is the source (sorry i should have included that)
I get the phenomenon with all standard settings from cura. I use v.4.6.2 and have an monoprice mini pro. But as the problems are already in the gcode i dont think it has anything to do with the printer. I since resliced using slic3r. The gcode here looks fine but in the print i still have some minor artifacts in the perimeters. since its not a cosmetic print i dont mind but its still wired.
