Autolift Hotend on Kickstarter

Post by Legion 2.3 »

Dear community

I discovered a new AUTOLIFT-HOTEND :!: on Kickstarter: ... r-hot-ends

This hotend lifts itself automatically for something like 0,5 mm when you retract the filament.
It uses a spring mechanism and micro-linear-bearings for that.

I think this could make 2 - or more - colour - printing, especially for larger objects, finally possible without the problems we actually have (scraping inactive nozzle, etc.).

Well, it´s quite expensive, but it could be a great update if it works.
I found something compareble here:
But I didn´t find out more about this modell yet (Merlin Hotend).

What do you think, can this work? Do you see any problems at the mechanics?

I'd like to see something like this but incorporating a cutoff in the nozzle to prevent oozing, something like a needle valve internally

The needle valve would stop oozing but the filament would stil melt to allmost liquid on the nozle causing some blobs. I've been researching a way to separate the two extruders and dumpin some filament in to some kind of ooze cup before printing again

Wow, autoretract hotends. This is exactly what I think the dual extruder system needs on the Felix 3.0! Would love to see anyone have this in action...
