I have a Anet A6 and it prints the preloaded items well. I have loaded and sliced a file I received from a friend that he has printed successfully on his printer of a similar make. When I print the file the bottom and top surfaces are good but the print gradually moves in the y direction about 1/4" while printing the part that is about 1/8" thick.
Any suggestions? I think it might be in the settings .
