Hi i’m new and just finished to build my k8400.
i’m quite please with the result of my first print. but my printer do not print on the center of the build platform. in Repetier it is placed in the center but it is print on the left side in front of the center. i’m not sure if i messed with the settings in printer configuration or what the problem is.

Hi,
You should have posted a screen capture of the Repetier placement screen.

The print area is smaller than the build plate area shown by Repetier. You can’t use the 4 left centimeter (i.e. left from the big black dot in Repetier) nor the 2 front centimeters. So the center of the usable area is more to the right and the back of the plate.

Hi
sorry for my late answer.
I reinstall repetier and now the prints are in the center
thanks a lot.
