marlin g-code

I have a creality ender 3 pro printer and have done a mainboard update (v4.2.7).Before this update I regularly used this bed level code: G90G28 ; Home all axisG1 Z5 ; Elevator Z axisG1 X32 Y36 ; Move to Position 1G1 Z0M0 ; Pause printG1 Z10 ; Elevator Z axisG1 X32 Y206 ; Move to Position 2G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X202 Y206 ; Move to Position 3G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X202 Y36 ; Move to Position 4G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X117 Y121 ; Move to Position 5G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X32 Y206 ; Move to Position 2G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X202 Y206 ; Move to Position 3G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X202 Y36 ; Move to Position 4G1 Z0M0 ; Pause printG1 Z5 ; Elevator Z axisG1 X32 Y36 ; Move to Position 1G1 Z0M0 ; Pause printG1 Z15M84 ; disable motorsThis worked perfectly, but now it no longer works with the new mainboard, the code for pausing (M0; Pause print) does not work and the printer continues as normal, I have already changed the code to G4 but this does not work either.Someone who can help me
