We don’t have a fan mount made up just yet, but if anyone would like to get a head start on making one, all the available FreeCAD source files are available here: http://devel.lulzbot.com/TAZ/accessories/dual_extruder/dual_extruder-1.0/source/
When will Lulzbot have a kit for dual extruders? I could order another hot end and print the parts, but would be nice to jump right to the dual extruder now. I would really like to use PVA/ABS prints.
Or ABS & HIPS.
And will either PVA or HIPS work reasonably as support material for ninjaflex?
Here is the new Lulzbot Dual extruder

And I think PVA is water soluble, thus very usefull for support
I know PVA is water soluble.
The question is whether HIPS or PVA work well as support material with Ninjaflex. Not all pairs of materials work well together for fused filament deposition.
I have an older TK-0 (pre Taz) that I built about two years ago. Would this new dual extruder work with it?
How difficult would it be to get Marlin working with a Rumba controller for dual extrusion?
it should physically fit. Worst case scenario the spacing for the X carriage itself should be unchanged, so you could just upgrade that bit.
Looks like the Rumba has two extruder control headers, so it should be easy enough to enable.
I’m told by tech service that ABS, HIPS and Ninjaflex work well together and that they are all extruded at about the same temp which helps them to bond well to each other.
Thanks! That’s good to know. Aside from compatibility, I wasn’t sure about the temperatures.
I just built the FlexyDually. I switched the stepper motor on my original TAZ4 extruder to a half height stepper and checked the calibration with it mounted on the dual extruder. I had to increase the Esteps from 848 to 957 to get it to extrude 100mm of ABS. I was surprised by this because I expected it to be about the same as before? Do the half height stepper motors have such different behavior from their full height brothers? Anyone else experience this?
