I battled with the original profile and the quick change because of the tip shaping always causing jams. Please ensure to double check your switch location settings and tube length, from the outlet to the splitter my longest runs are about 475mm the bowden to the extruder is 550, this is giving near perfect loading without a glob, the extrusion could be tuned abit to help with the purge line efficiency. I've learned, if you make time adjustments do it one second at a time and test, it can have a huge impact. the park location of the filament is also crucial for this profile to work, please refer to the photos for reference, all of the filaments will visually be aligned below the splitter.
