Printing not startet in the Center (no replies)

Hi today i have print for the first time, the android object.
The printer moves to his homepositon and after this the printer moves down and to the left front => it works.

After this print i have would like to print the X Carriage Dial Gauge Mount, so i put it in to Repetier to get the geode.
My settings ar these:[attachment 23002 printSettings.ini]

After i have slice the code and toke it to Octoprint the printer would not start the printing in the center of the bed. It starts on the left front side of the bed.

So i have look in the both geodes, the first point is:
at android: G1 X9.279 Y-28.452
at my Repiter Slicer: G1 X66.630 Y60.684

So wehre in the config of Slicer can i fix m problem, that my center ist at x0 and y0??

Sorry for my bad english :-)
