They are printed quite a to the left of where they should be. you need to move the endstop plug on the controller to the Y min endstop position (presuming a ramps type controller) and set #define Y_HOME_DIR to -1 (ie home to min endstop) If this this already -1, then you need to invert the Y axis of travel, find #define INVERT_Y_DIR if this is set to true change it to false, its it is set to false change it to true. Hope it helps. Use M428 to set a persistent offset to the native home position and coordinate space by assigning the current position as the native home position. Here is a pic of our setup: Electrical.

The result is that any movement command after this will be lowered by 0.1 mm in the Z-axis. When printing large prints, the skirt, brim or the object itself is printed outside the heated bed. The current position is set to the native home position. A prerequisite of this method is that it requires the G-code command [M206](https://reprap.org/wiki/G-code#M206:_Offset_axes) to be supported by your firmware; note that not all 3D printer firmware solutions are able to use this G-code command for axes offset definition. When I start a print I have to manually twist the Z axis up a bit so it doesn't force filament through other areas (happened once and caught it and cleaned it before permanent damage).
