[Modifying gcode on export?]

Thanks a ton! I didn't know the startup Gcode field overrode the default commands. Seems to be working great now. 👍

[Modifying gcode on export?]

Hi, still relatively new to using Cura for only about a year. I noticed that whenever I create a gcode file to print on my Ender 3, it is written so the bed heats up first, waits until it is up to temp, then starts heating the extruder. I believe I can make small savings in print time by modifying it to preheat both at the same time. I have written out the gcode that Cura spits out below.

M140 S62
M105
M190 S62
M104 S210
M105
M109 S210

 

I rearranged this code to be:

 

M140 S62

M104 S210

M105

M104 S210

M109 S210

 

This seemed to work in preheating both at once. Is there a capability in Cura to change this on all gcode files that Cura generates? I looked in the printer settings and it seems the custom start gcode appears after this code snippet. I have attached an example gcode file to this post. My cura version is 5.2.1. I would greatly appreciate any help anyone can provide. Thanks!
