Sarchopilus

Hi there everyone. I hope I am not asking the same question as someone else, but I couldn't seem to find anyone else having this problem. So I recently built my UM2 and after installing the firmware I go to do the initial bed leveling it doesn't go to the first position correctly. From what I can tell, from watching videos, The first position the print head should move to is the back center of the build plate close to the rear adjustment screw. If I am wrong please someone correct me on this. Instead of going there it goes to the front center of the build plate. Then it goes to the right and the left. So essentially it does the bed leveling in a straight line. Have I done something wrong with the firmware? Any suggestions would be greatly appreciated. Thank you.
