I have ender 3 pro with skr mini 3.0 and TFT35 3.0 display and BLtouch and smart filament sensor and sprite extruder.  
When I am printing over Octoprint it doesn’t print in the center of bed and everytime I want to print on whole bed it doesn’t because on right side I have 3cm free space and on top of bed 1.5 cm free bed. I use marlin 2.1.2.4  
how to setup so I can use whole bed size and when I print on ceter of the bed it will be center.  
// The size of the printable area

#define X\_BED\_SIZE 225

#define Y\_BED\_SIZE 235

// Travel limits (linear=mm, rotational=°) after homing, corresponding to endstop positions.

#define X\_MIN\_POS 0

#define Y\_MIN\_POS 0

#define Z\_MIN\_POS 0

#define X\_MAX\_POS X\_BED\_SIZE

#define Y\_MAX\_POS Y\_BED\_SIZE

#define Z\_MAX\_POS 250  
#define NOZZLE\_TO\_PROBE\_OFFSET { -35, -45, -1.06 }

// Most probes should stay away from the edges of the bed, but

// with NOZZLE\_AS\_PROBE this can be negative for a wider probing area.

#define PROBING\_MARGIN 10

// X and Y axis travel speed (mm/min) between probes

#define XY\_PROBE\_FEEDRATE (133\*60)

// Feedrate (mm/min) for the first approach when double-probing (MULTIPLE\_PROBING == 2)

#define Z\_PROBE\_FEEDRATE\_FAST (4\*60)

// Feedrate (mm/min) for the “accurate” probe of each point

#define Z\_PROBE\_FEEDRATE\_SLOW (Z\_PROBE\_FEEDRATE\_FAST / 2)

I found out with AI I should use M206 X20 Y12 and than M500 to save  
Now is ok I get center and whole bead to print.
