Cura keeps resetting start gcode

[Ch3vr0n 2]

I have a annoying issue since updating to 4.13.1 and its that cura is constantly resetting my start gcode for temperature values. My preferred config is as follows (slightly modified from default)

However for some damn weird annoying reason cura keeps resetting the pre-levelling and final heating section temperatures to

And to make it even more weird. When i change it, it's remembered for a few times closing and starting, and after a few times it's back to reset. I wanna know how to fix this without loosing my printer profile & custom quality& material profiles

Are you perhaps loading old projects? Projects contain all settings, including start & end gcode.

Well i just tried and it's a 3mf file that had the embedded image so i'm pretty sure it saved with 4.13.1. So you're telling me, start/endcode settings that may have changed since the project was created get overridden and i have to redo them all? That shouldn't be happening. I don't mind the sidebar stuff getting overridden, that's the job. But start/end gcode shouldn't get replaced

Well, that's how it works in Cura. Cura can't read your mind and know what settings you do or don't want to load from the project. It would be nice if you could select from a list of options which (sets of) settings you want to load from the project when loading a project.

It probably does ask, but with limited choice. I'm guessing the first "dropdown" when you open is for the startcode as it asks if you want to update the printer or add a new one. But there's no way to select to KEEP the current one

You are guessing incorrectly.

 

Loading settings from projects is currently "all or nothing". It would be nice if there were options to eg keep the current preferences, what settings are visible, and the machine settings. There are no such options. The whole state of the application is imported from the project file. All that dropdown does, is letting you select what "printer instance" these settings are loaded in to; you can have multiple of the same printers configured in Cura.
