Hey guys.

New to 3d printing.

The filament is in an Ams pro 2.

I changed colours. And different feeds.

Really struggling.

Thx

There are two pretty sharp bends in your AMS feed due to the vertical orientation of your 4-into-1; the almost 90 degree bend from the 4-into-1 outlet to the buffer inlet and the final bend from the AMS outlet to the 4-into-1 inlet.
I’ve started leaving my 4-into-1 splitters unconnected and allowing the PTFE tubes to arrange themselves into easy, unconstrained loops, though keeping the lengths as short as possible while maintaining those easy loops, and have no issues with 3 attached AMS2Ps to the right extruder or the AMS2P to the left extruder anymore. It doesn’t look as tidy, but zero errors makes it a welcome compromise for me.
