I recently installed SkyNet3D V1.1 on my Anet A8 printer. When I prepare the printer and select "auto home" it moves the head close to the upper right hand side of the bed. How do I change these settings so the printer auto homes to the center of the bed? Any help is appreciated.

Please note that Skynet3D is OBSOLETE, this was a fork from Marlin Firmware that was created to support the "odd" displays (due to alternative pin layout) Anet use on their printers and has been completely integrated in Marlin.

Note that homing is used to hit the end stops to determine the positioning of the head. There is no such thing as homing in the center of the bed (apart from the Z-axis). How would the head know where it is just after switching the printer on?

When using the constant:

#define Z_SAFE_HOMING 

the printer is instructed to move the head to (in this case to the middle of the bed):

#define Z_SAFE_HOMING_X_POINT (X_BED_SIZE / 2) // X point for Z homing when homing all axis (G28). #define Z_SAFE_HOMING_Y_POINT (Y_BED_SIZE / 2) // Y point for Z homing when homing all axis (G28). 

after sending the G28 homing command.

Basically it wil home X and Y, then move to the instructed position (in the example the middle of the bed) and then home Z.
