[Solved] Start gcode repeating after first layer  

Start gcode repeating after first layer

My start gcode is modified to heat the hotend to 70%, then doing the bed leveling, then heating to the 100%:

M862.3 P "[printer_model]" ; printer model check
M862.1 P[nozzle_diameter] ; nozzle diameter check
M115 U3.12.2 ; tell printer latest fw version
G90 ; use absolute coordinates
M83 ; extruder relative mode
M104 S{first_layer_temperature[0]*0.7} ; set no-ooze nozzle temp while bed heats
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S{first_layer_temperature[0]*0.7} ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
M104 S[first_layer_temperature] ; set extruder temp
M109 S[first_layer_temperature] ; wait for extruder temp
{if filament_settings_id[initial_tool]=~/.*Prusament PA11.*/}
G1 Z0.3 F720
G1 Y-3 F1000 ; go outside print area
G92 E0
G1 X60 E9 F1000 ; intro line
G1 X100 E9 F1000 ; intro line
{else}
G1 Z0.2 F720

G1 X100 E12.5 F1000 ; intro line
{endif}
G92 E0
M221 S{if layer_height<0.075}100{else}95{endif}

; Don't change E values below. Excessive value can damage the printer.
{if print_settings_id=~/.*(DETAIL @MK3|QUALITY @MK3).*/}M907 E430 ; set extruder motor current{endif}
{if print_settings_id=~/.*(SPEED @MK3|DRAFT @MK3).*/}M907 E538 ; set extruder motor current{endif}

That's the only thing I changed in the setting all else is default.

The start gcode works as expected, however, after the first layer, the print just stops for a few seconds, then sets hotend temp to /2, then restarting the whole print with the bed leveling and everything. What's causing that???? Please help!
