    Hey BigBoxers!
    So, I have this dual hybrid B.B. converted to IDEX using Greg’s Bowden IDEX conversion but replacing the Bowden Titans for 2 remote direct drive Zesty Nimble extruders. But I never liked the ooze shield or purge tower or (sorry Greg) Greg’s oozeless ram purge script. So, I added some silicone rubber wipes running along the sides of the bed and a stainless steel plate under each nozzle where they park when not in use. This way the filament does not bleed out while idle because it is blocked shut by the steel plate, and the silicone rubber wipe keeps cleaning the nozzle every time the nozzle moves in either direction; either going to print or going to idle. The result is a clean print and zero bleeding from the nozzles. Still running tests but as you can see it looks pretty good! See video please.

    Wow! I'm not an IDEX convert, but that's impressive! Beautiful implementation of your idea.

    This is TOO much! every time I get a plan to improve my BB along comes another mod !!!

    Only kidding !!! great idea, and fascinated to know that the ooze problem (normally a quick flick with a bronze wire brush, then let it print a perimeter to get things flowing) fix works so well.

    Great idea! How have you mounted this? Replaced the Z Rod caps?

    The wipes are superglued to the rod caps, the steel plates are attached to a 3d printed piece that screws to the Y carriages, I just drilled a vertical hole centered between the belts to attach them with M3 screws..
