AM8 Belted extruder (geared)

thingiverse

geared extruder for bowden set up on Anet AM8 or custom printer on 2020 or2040 extruded aluminum. this thing was made to be used with the stock extruder feed parts or aftermarket bowden extruder plate. the pulley/gear file included was something i found here on thingiverse but i cannot find it again to thank the guy/gal that made them. and to give them credit so if the belted extruder pulleys are yours please let me know so i can fix this post. Materials needed: Qty. Description. 1 5mmx 60mm screw/bolt 1 5mmx8mm Nut 1 5mmx8mm Nylok nut/lock nut(jam nut) 2 22x7x8id mm bearing i believe z608 or skate bearigns 1 extruder feed plate/mounting plate lever system 3 35x3 mm screws/bolts (mounting stepper) a few 188 mm closed loop gt2 timing belts. ( i made my own with some superglue and some spare gt2 timing belt, follow online instructions use belt jig found here on thingiverse.) CAUTION!! home made belts tend to break after a few prints. notes when assembling be a bit patient. every hole is made to hug the part that goes in it so push slowly but with force on the bearings as for the nuts that go into the motor mounting holes use a 10mm screw and place the nut over the hole for it and screw the screw in from the other side as to manually seat it into place. it is the easiest way i have found plus it breaks nothing and is and even pull all the way through. also place belt on large pulley first ans shimmy the extruder pulley connected to the stepper motor into the loop and once the motor is mounted it should take any slack left in the belt. Enjoy! Modify! Share!
