I’ve seen a video online where someone is completing their H2D/H2C maintenance, and he removes the left nozzle in order to place a couple of drops of oil in the area just behind the nozzle - hence keeping it nice and free when the nozzle slides up/down. I don’t recall seeing this in the Bambulab maintenance guide? Is this a recommended step?
EDIT - Ignore - I need to pay closer attention! lol
