3D-Proto's Dual Parking Extruder

There are several different dual extrusion systems out there today. While dial extruders can be nice to have, they also very commonly introduce new problems into the 3D printing equation. Such problems include scratching and oozing. 3D-Proto thinks that they may have come up with a solution to both of these issues with a new Dual Parking Extrusion system. Basically the system takes the extruder not in use and parks it to the side, returning it back to the build area once it is needed again. This keeps the extruder away from the print while not in use. More details on this new extrusion system can be found here: http://3dprint.com/26590/dual-parking-extruder/

That's a cool idea! But maybe a video would be better than a picture? The reason is it doesn't look like this really works. Maybe this new system isn't really here today??? The left hand extruder doesn't have anything plugged into that big molex connector. And if you look at how it works... The center part of the extruder can't ever mate with the left hand extruder because those big wires are in the way. Can we have them tell us when they actually have a working unit and ask them to send us a video of it?

Oops, here is the video. It's in the article link:

That is cool! I want one!

That's really cool. The only thing is that he says this solves the loss of x-axis area which it does not. If anything it causes a great loss of area because instead of two nozzles right next to each other you now have the "magnet carriage" width in between them. Looking at what he has set up in that video there would be no way for either nozzle to reach the opposite side of the print surface without crashing into the parked piece that's already there. It definitely solves the dragging second nozzle and ooze problems though. It's a creative solution that I hope he continues to develop.

Very cool.

This is very similar to an old concept of mine ( which would have used a single selonoid for locking ) in 2012 : https://www.youtube.com/watch?v=EoPj...MgSIqNRqNYzh6w
And that idea was based on one by Ezra from Trinitylabs.
But never had time to go as far with it as you did.

Show us prints :)
