Details
The Unique Prototyping extruder was designed to be a drop-in replacement for the popular Wade's extruder, for those who are interested in upgrading to a geared stepper motor. It is also great for new machines, including the beginner who doesn't want to deal with the headaches and challenges associated with the extruders that are less forgiving. The extruder is designed to fit the J-Head nozzle and the J-Head mounting plate. Using the optional flush-mount spacer, the extruder can also mount atop a flush-mount style hot end, such as the Budaschnozzle. An open slot on the side of the extruder allows visibility of the hobbed pulley as it feeds the filament. The heavy duty design allows the geared stepper motor to rigidly attach to the main extruder housing with three screws, preventing any unwanted movement of the motor while extruding.
The quick-change filament feature allows you to quickly change out filament with just a few turns of a single thumbscrew. You do not have to adjust the spring tension each time you change out filament. The springs are separate from the thumbscrew, so the spring tension will be retained. To change out filament, simply back off the thumbscrew by turning it a few times and the pressure on the filament will be relieved. You do not need to completely remove the thumbscrew like the picture shows unless you want full access to the hobbed pulley. Remove filament, insert new filament, then tighten the thumbscrew back up and you are done!
