#Place the 2 large bolts in place from underneath the extruder assembly back plate. Hold those in place with one hand, and with the other hand, place the filament motor/gear assembly, aligning the holes with the bolts. You may have to jiggle the filament motor/gear assembly to get the bolts to line up, initially or during tightening. | #Place the 2 large bolts in place from underneath the extruder assembly back plate.

#Attach the completed extruder assembly to the Y-axis assembly by sliding the wide-V shaped bottom of the extruder assembly into the similarly-shaped receiving slot, ensuring it is seated all the way down (apply gentle pressure). Insert the remaining bolt and tighten using 2.5mm Allen wrench. (Suggestion: first put the bolt in the extruder assembly, holding in place with the Allen wrench, and then seat the extruder assembly into the receiving slot; then tighten the bolt.) | #Attach the completed extruder assembly to the Y-axis assembly by sliding the wide-V shaped bottom of the extruder assembly into the similarly-shaped receiving slot, ensuring it is seated all the way down (apply gentle pressure).

#Reload filament by inserting filament through the top of the extruder assembly and pushing down as far as possible; approximately 3 inches/75mm of filament can be pushed in after initial entry into the aluminum plate of the Budaschnozzle before the filament end “hits bottom” at the actual nozzle. (Note: if a bulb of filament makes this difficult, snip off some filament with scissors at the point where the filament is the proper diameter.) | #Reload filament by inserting filament through the top of the extruder assembly and pushing down as far as possible; approximately 3 inches/75mm of filament can be pushed in after initial entry into the aluminum plate of the Budaschnozzle before the filament end “hits bottom” at the actual nozzle.
