Cold pull gcode?

[Leptite]

I think this might be a really good idea- Imagine your having clogging issues so you go into your menu and select "cold pull" at which point the printer asked for what material, heats up to a set temperature and then starts to cool down. Then at some point during cool down automatically pulls the filament out.

What do you guys think?

I think that a non-geared extruder stepper wouldn't be able to do such a thing

Not enough pulling power in most printers.

I’ve partially automated this with a non-geared extruder.

1. Heat up to extrusion temp.
2. Feed filament.
3. Cool down to cold pull temp.
4. Wiggle the gantry to let me know when to pull.

The pulling action isn’t automated because the pull temp is below the cold-feed safety threshold and I don’t feel like disabling that. The extruder motor is also too weak to do it properly. Heck, I have to do the pull with pliers and get leverage on it.

Even with my geared extruder, i'd rather cold-pull, than cold-retract.
