Yes you can change the start gcode. You can do this in the machine settings In CURA.
The reason it heats the bed then the nozzle is to reduce the amount of oozing from the nozzle as it takes a long time for the bed to heat up. The oozing creates a cavity in the nozzle which requires more priming.
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 these I wanted to delete or be able to modify.
Ok on heating the bed first, I hadn't thought about the oozing issue, although my question was more about why, for the nozzle heating does Cura use an M104 followed by an M109. Wouldn't just the M109 serve the same purpose?

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

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 {ma
