Hi all!

So I have been dealing with this since I set the printer up and I can not get it to print! I just unboxed a CR-10. Assembly seemed straight forward. I used Cura and thingverse to upload a simple file and used recommend settings.The machine homes out correctly in the front left corner. I did level the table, the y-axis switches are plugged in correctly. When I go to run the print it comes over in the x, down in the z to print height, and then starts vibrating and shaking as the y-axis try’s to run the wrong direction! It is trying to run towards me when it should go back so the print will be in the middle of the table?! So the belt starts slipping over the cog servo motors and I have to shut it off! I cant find anything in Cura to reverse the Y-axis. But it must be in the g-code or firmware? Because it homes out correctly… Help Please!!
