Need advice please

Hi Guys am new to all this only has my laser 2 weeks.

Just starting to play with my Ortur master 2 and geeting some funny results
Just lasered some name tags out of plastic and for some reason the laser started in the wrong place but when it came around it was in the right place plus it is not burning a perfect circle as you can see in the pic.
Has anyone else had this problem if so how did you solve it
