Please Help for AutoLevel Tronxy X5S

Hi, I apologize for the corrupt English first.I have a Tronxy X5S 3d printer. And I bought a sensor( SN04-N NPN) to add autolevel property to the printer. I thought I would be able to get rid of the small curves on the hotbed. I've arranged my commands according to autolevel as follows. But when I want to print a large shape, the extruder remains in the air at some points of the hotbed, print properly at some points, and at some points worth the hotbed(no filament output). So the autolevel property is not working properly. Can you help me? What am I doing wrong?

I have been using Bilinear Bed Leveling for quite some time now. I find that you can level the bed using the LCD menu commands.

I have found that on my 3D Printer could level the bed using the LCD rotary and Click Bed Leveling, after the bed is leveled the Bed leveling data can be saved.
I have a 8Y x 6X matrix or 48 points. I would not want to bed level before every print. I can level the bed once a week or longer before needing leveled again.

Using the LCD Store Settings menu command.
Then when I want to print I simply restore the saved bed leveling data Using "M420 S1"

Video "Restore Bed Leveling Data Bi-Linear" On this video was using a 5Y x 4X matrix or 20 Points.
You can also save the Data Using M500

Thanks for the response. But I didn't understand. Is my code wrong? I did a lot of experiment with Autolevel. I recently wrote these codes. The Auyolevel process is running. Autolevel Measures from certain points of the table. When it starts to print, moving the table up and down according to the slope, it should keep the distance between the nozzle and the table in each area. But because the table does not move up and down, the nozzle touches the table in some places, and nozzle stays above it with some places.

#define MIN_PROBE_EDGE 20
#define X_PROBE_OFFSET_FROM_EXTRUDER -40
#define Y_PROBE_OFFSET_FROM_EXTRUDER 20

#define X_BED_SIZE 330 - edge = 310 - 40 = 270
#define Y_BED_SIZE 320 - edge = 300 - 20 = 280

#define LEFT_PROBE_BED_POSITION (60)
#define RIGHT_PROBE_BED_POSITION (270) // how far can nozzle travel over this bed edge.
#define FRONT_PROBE_BED_POSITION (40)
#define BACK_PROBE_BED_POSITION (280) // Sensor cannot travel beyond the bed rear edge

Please watch to understand my problem.
