UM3 style dual extrusion upgrade for UM2+Ext?

[ScarletImpaler 0]

Hello!

I was wondering if anyone had successfully upgraded an UM2+E (or I guess any other UM2) with a dual extrusion set up, like what the UM3 has. One nozzle printing PVA as support and such.

I bought the UM2+E primarily for build volume, but not knowing what the UM3 does and just how amazingly useful the dual extrusion with PVA supports really is. UM3 Extended is out of my budget, so if an upgrade for my UM2+E is out there, to make it on par with UM3, I'd want to get it done!

Thank you!

Depends on what you consider UM3 style.

You can achieve the same print quality and almost same user friendliness with the tool changer (scroll a little back and forth get get an impression) a community project which is in beta testing right now.

The good thing, it's by far the least expensive dual extrusion approach available. Besides the 2nd feeder and hotend it's just 30 €/$. And it leaves single extrusion printing completely unchanged.

There are indeed several upgrades to the UM2 for dual printing but I believe foehnsturm's is the best.
