The Bulldog extruder seems to be a fine addition to my printer, however it is not configured as well out of the box for use with a bowden cable as it is for a direct drive. The extruder comes with a filament guide for 1.75 and 3mm filament that screws into the base of the extruder and hopefully prevents the formation spaghetti if the hotend stops working. When screwing the provided push fittings into the extruder there is a lot more space (I found out) for spaghetti to occur. This thing is a small extension piece that provides the filament guide and still has an M6 thread for the bowden push fitting
