Here last week-end I connected the printer, a Afinibot A3, and began to heat it up for the first time. I do have some STL-files and my choice was a round block. After slicing and temperature check I used the print command. I could see that the extruder was moving in ovals and not in circels until it was almost done. I have sent the picture to where I bought the printer and the sellers answer was:" You are running too fast or too cold". The print is filled with air. Can someone make this error a little easier for me to understand?
