If there is serious mud leakage at the upper end of the extruder, the distance d between the coupling and the motor can be appropriately increased.
Sealing principle of CERAMBOT extruder: CERAMBOT is sealed with a silicone rubber gasket, and the silicone rubber gasket is compressed and deformed by using a coupling and a transparent gasket. If the distance d is too small, the sealing at the tail end is not good.
