In that snippet, you have put in actual numbers for the temperatures. DON'T do that.
Cura does not look for M104, M140, M109 or M190 commands, but instead it looks for the literal text {material_print_temperature_layer_0} resp. {material_bed_temperature_layer_0}. If you fill in numbers yourself, Cura will still add its own preheat commands. If you put in the actual text, including the accolades, then Cura will see your preheat sequence (and it will fill in the numbers for you).

Hi, thanks for the response. I realise that I can create my own start code in Cura but Cura inserts its own start code prior to the the user defined one e.g. M190 S65 M104 S200 M109 S200 It was t

What I said was: you can, as pointed out in this thread. I have copy/pasted it below so you don't have to go look it up.
Cura checks if the start gcode contains commands to heat up the hotend and bed before the print is started. If the start gcode does not have command to do that, CuraEngine adds the three lines (M190, M104, M109) before your start gcode just to make sure that the hotend is not cold before starting the actual print.
If you don't want Cura to add these lines, make sure your start gcode contains lines which have {material_print_temperature} and {material_bed_temperature} or {material_print_temperature_layer_0} and {material_bed_temperature_layer_0} in them respectively. eg:
;... code that should go before the heatup sequence here! M104 S{material_print_temperature_layer_0} ;Start heating extruder M140 S{material_bed_temperature_layer_0} ;Start heating bed M109 S{material_print_temperature_layer_0} ;Wait for extruder to reach temp before proceeding M190 S{material_bed_temperature_layer_0} ;Wait for bed to reach temp before proceedingBe sure NOT to put in the actual temperatures; Cura will do that for you.

Thank you for your help.
like I told @GregValiant (he also helped greatly in another thread), this is the code that I use on Superslicer:
I have also tried the Cura's original g-code for ender 3 pro with addidtion of temp (just to see if somehing happens):
And this results in this code when generated a g-code by Cura:
I just wanted to use it like Superslicer, that is while printer is homing it also warming up the bed and nozzle and I think it is much efficient this way. But after reading some of the comments, I understand that there is also a safety aspect involved.
