@rtyr can we include a sanity check for other less experienced users like me seeing this? I initially commented with that link, but deleted the comment because of the report text, so we obviously needed you :). @erseln says "this is actually also printed this way", which implies extrusion, so perhaps the right expression - which seems obvious once it's pointed out and you've confirmed it, but it made me wonder what they meant - could be "the printer head actually follows those paths"? No filament is intended to leave the extruder during the ramming, but I guess it happens above the wipe tower in case there's leakage to avoid marring any objects? If that's right, then the text of the explanation could include "The head is moved across the wipe tower during ramming to account for any cases where lower quality filament might lead to leakage, and ensures that this will deposit on the tower rather than objects."
