Has anyone actually gotten this to work? I have tried virtually all of the trouble shooting steps (the few there are) and no matter what the filament seems to not be loading far enough to reach to the printers extruder. I load the filament (t0) in clip it using the clippy change to another filament (t1,t2,t3) so the chameleon backs itself out then when going back to (t0) it does not send enough filament thru to reach the printers extruder.. What am I missing here?
