I managed to get the printer up and running with the single extruder. But getting the cable through the splitter is rather hard cause the cable needs to enter the splitter at specific curve to be able to come out of the other end. While printing with both extruders this causes an issue because the second extruder won't be able to wiggle the second filament through the splitter. Anyone got any suggestions how this can be solved ? I have been taking it apart multiple time and I'm not sure what's setup incorrectly.

For me the filament got stuck on the ends/starts of the metal connectors PC4-M5 Coupling (x3). The holes are smaller then the flexitube holes. So i drilled the holes of the metal connectors over with 2.38mm drill. Well first i used smal file and it was a massive improvment.
We've updated cura to increase distance of filament unload between dual extrusion switches for the Axis 3d printer.

Unfortunately it is a bad design. I am going to use the pictures from the web and reduce the bottom tube length to almost nothing. Also I am going to try a bigger loop for the extrusion. You are correct on the specific curve.
