[Feature Request] Filament diameter modifier, temperature modifier, cone supports and other ideas

[Alpacad]

Version

2.3.1+win64

Introduction

Maybe this feature request could be useless, but I hope someone would share my opinion and bring inspiration for future releases.

List of feature requests

• Possibility to change filament diameter via gcode placeholder / modifiers (for correct extrusion when changing color / material);
• Vary the flow through modifiers (for those who use different flows for different filaments, useful for color and / or spool change);
• Set a specific temperature for the bridge perimeters and overhangs (it could be useless to implement it, because if you want to set it lower than the printing temperature, the nozzle may not cool down in time, but it would help those who want a higher temperature for a better interlayer adhesion, but good bridging and overhangs quality) [N.B. I recognize that this is probably not doable];
• Vary the temperature also through modifiers (currently this can only be done using using the z_height placeholder and setting it from gcode);
• Cone supports (more precisely hourglass shaped) to support large flat parts and save material (this could also be useless if tree supports were implemented, but could be more useful with large suspended flat areas, like circles or rectangles);
• Ironing on the last layer of dense supports / raft before the model, for a smooth surface to support flat parts.

You can add M221 Sxxx command (flow) along with M600. Otherwise these requests are basically a duplicates of #3635, #2002, etc.

• Set a specific temperature for the bridge perimeters and overhangs

I don't see it as a good idea. It takes quite long time for the temperature to be changed/stabilized, so it would mainly lead to temperature destabilization without any actual positive outcome.

• Cone supports (more precisely hourglass shaped)_ to support large flat parts and save material (this could also be useless if tree supports were implemented, but could be more useful with large suspended flat areas, like circles or rectangles);

Tree supports are planned. Plus there is already similar FR #4128.

• Ironing on the last layer of dense supports / raft_ before the model, for a smooth surface to support flat parts.

I made some tests with SuperSlicer and the results were not so convincing. Please open separate issue on this, preferably with some examples, where this feature helped.

Side note. It is preferable to not combine too many topics in one issue.

Closing.
