MMU2 filament load inspection through mirror under Lack table as enclosure

thingiverse

I highly recommend installing a mirror directly above the MMU2 that's situated beneath a Lack table, serving as an enclosure. This setup provides a fantastic view of the filament loading process. Initially, I experienced difficulties in spotting the PTFE tubes when manually inserting new filament to switch colors for a multi-material print. This issue became particularly pronounced when dealing with more than five different colors. To resolve this, it's essential to separate color usage along the Z-axis. By doing so, switching between two or more colors during printing becomes much simpler, provided you swap them mid-process. Additionally, having an unobstructed view of the MMU2 from above greatly facilitates inspection and maintenance tasks.
