I think that your post predates my last one. Changing to the Revo unit does seem have made things worse. In this case the Bambu type wiper was cutting the filament but it was also rolling it onto the exposed Revo hotend next to the tip. Tonight I changed the wiper to the silicon type and this seems to have fully fixed the problem. That’s what my last post here was about. Tomorrow I can film the silicon wiper working if that’s what you are requesting. I don’t really want to switch back to the Bambu one though.

This is not what you asked for. It’s of the modified silicon wiper. Best video I could do. But is clear that the nozzle now gets a comprehensive wipe.
