Dual Filament position
Just got the dual tool unit and started printing . Not sure how I feel about the filament roll position on the side of the machine . The upper spool has a perfect alignment . The lower spool seems to have a tug on the PTFE tube and seem over time it may cause premature wear and tear . Worried this may cause filament drag considering there’s a good 2 foot plus of filament that has to get loaded to reach the extruder . Seems lime it screams for a little adapte with a bearing and wheel to ease filament in .

I think you are right...

The spool positioning on the XL feels very half baked. I'm in the process of routing it from a shelf above the printer with some PTFE tubes. Works fine for the single tool unit I have--waiting for the additional tool heads to become available.

This is an XL thingy in the MK4 sub. Can you move it there yourself? 😜
