Permanently change the default temperature nozzle/bed values for a particular filament type.

[Mitchimus 0]

I overrode the temperature values for PETG in the materials section only to get this code.

See inserted image immediately after this line.

 

 

It looks to me like CURA for some reason always defaults back to the template values. Can someone tell me why? Or am I just Barking up the wrong tree?

See inserted G-Code immediately after this line.

Not 100% sure but material related settings should go into material profiles. So you should create a new material in the settings and then select this custom material.

I was just watching a video on YouTube that explains what I think you are talking about https://youtu.be/nQLJrSf4aXE .  Hope this helps...
