saw somebody in this community did a print of maker muses tolerance calibration with dual extrusion. thought I give my newly dialed in printer a try
sliced with 1.0 extrusion multiplier in S3D
only get 0.5 and 0.4 to move freely 
honestly I’m just happy it printed without tower, ooze shield and purge bucket!
@Step_Cia ​ I’m glad I’m not the only one that uses a foam dust cleaner on my filiment pre extruder! I use dabber brush foam for mine they are cylindar shaped all I have to do is pop them off the wood dowel and poke a paper clip through them
yours more thoughtful. mine just cut on the side and slip the filament in and hope it doesn’t fall off 
@Step_Cia Very clean print!
Nicely done!
I use a bit of foam wrapped around the filament and pinched with a small binder clip. Cribbed from a setup I liked at the local makerspace.
