How to change default heat up temp?

So… every time i start a new print, the printer heats up to 210c then i would have to manually have to adjust it down to 190, where can i find the setting to change the default heatup to 190?

Look in Cura settings/Filament (don’t forget to save).

You would need to make these changes in the Cura configuration.

And what if printing from Sd card card is issue?

If you set it up in the configuration in Cura and then slice the project the settings will be in the Gcode.
