The Dual Extrusion Splitter for the Axis 3d printer has been updated.
The new design reduces the likelihood of jamming and provides a straighter path for the filament. We've also removed the need for the short PTFE tubes inside the splitter.
It uses the same hardware already included with the original splitter however you will also need three M3 x 10mm or longer bolts and three M3 nyloc nuts to secure the two halves of the splitter together.
The new splitter is available for download here:
In addition to the updated splitter the instruction for dual extrusion have been updated too. Specifically with the addition of step 9 of stage 4:

By adding the post processing step it removes the pauses that Cura inserts between switches.
Time-lapse of printing, both approx. 6 hours. (unfortunately we ran out of daylight before the cat print finished):
I could not get v2 splitter to hand feed out of one side even. Printed in PETG on a Prusa i3 MK3S... twice, once at .2 layers and then again at .1. Second one worked a little better but still couldn’t feed past the entry for the E2 side. E1 would work. I gave up with those and went back to the one that shipped with it.
Wrong size embedded nut for one screw on the hot end side, so could never fully close, had a crack. Wrong size screw sent for middle or maybe I lost it and that was just the extra small screw they sent (though directions i don’t think even mention the middle). I had 2.5mm screw so used that to mostly get tight.
was able to feed by hand so got my hopes up! and crushed. Whenever I extracted E2 after extruding a test, the stringing and blob at the end prevented it from coming back in.
thinking about it, there just seems to be too many variables for dual extrusion to ever be very reliable for like this. Going back to single.
The crap filament from Makertech, the red and the blue came in packages that were punctured before I even got them. The red and blue has always been brittle.
Yeah, the new splitter is junk. I thought I was doing well asking someone else to print me one with a better printer. I was wrong.
Im done with dual extrusion until my Prusa gets here.
So I had a friend that can print, print me one of these new designs. I will have to say that it is worse than the original. My filament, the red and the blue that came with the machine keep breaking off inside. I didnt have this bad of a problem using the original design once I got it figured out.
Man this is just a bad design.
Nice... Thanks for that updaye... it makes dualprinting worthy again :). Just one tiny problem after replacing the "M" codes in gcode the printer wants to start the print before nozzle temp is reached, but i guess its not that hard to pre heat the nozzle or pause the print...yingyang print ia printed with dualextruder v1 only code is altered... No gloggs/ absolute no problems duri g print (ca 45min) :)
If that solution is working well... would it mean that there is no more problem to print even with 3 or 4 colors. As long they are same material (same temperature).
But, as far as i know is the extruder amount in marlin still limited. And also the slicer have to support it.
