Hi All!

So I just got my first printer the CR-10. I unboxed it and downloaded a few different step files and put them into Cura. I used settings a trusted individual on youtube suggested along with trying the recommend settings from Cura. No matter what I do, the first thing the printer does is home, then dive down at an angle in the front of the table and starts printing lines back and forth. It might be a nozzle wipe routine?

But either way when it dives down its making a loud horrible knocking noise! It vibrates the whole bed and I was told from a friend it could be stepper issue? Has anyone ever heard of this?! I have a video I could send to someone to show exactly what its doing but if anyone could please help that would be much appreciated! I can put it in control and move the X & Y axis smoothly so its not always doing it?! Just when I go to run the program?! Please Help! Thank you!!
