Stupid question, start/end gcode commands for ender 3


Just got a creality ender 3, and its not on the list of printers. I selected other and input the specs for the printer, but the command codes are empty except for “g28” I would like to add a nozzle purge and other things. How do I do this?


Find a profile that works (for example in Cura) and copy / paste the start / end gcode section.
