Ender 3 X Axis Motor Damper Fix (Non Removable Gears)
Description
__Update: New gear added! This one has a solid infill for better adhesion and is slightly longer (3mm) to improve spacing with belt. This design requires a few more washers, though.__ __Make sure you don't follow the fourth diagram! It is modeled wrong with the gear in the wrong position.__ EDIT: I have updated the model to be in centimeters size and rotated properly for printing. You can re-download or just rotate/resize the model (10x). If the cylinder is too small to fit (since every printer has different extrusion rates) you can just use a piece of paper to wrap around the gear or design your own. You can also change its scaling in your slicer to make it larger or print the larger sized one. This build will allow you to add motor dampers to the Ender 3 (that has non-removable gears) without replacing parts. Things you'll need: 6-12 washers, 2 M3x8 Screws, Superglue (If you do not have washers, you can print 2m high cylinders, but it isn't recommended). Watch out for the motor damper. Its hole MUST be larger than the pulley and if it has two little protruding bumps, they need to be filed off. Only a small amount of superglue is actually needed. If you add too much and it overflows, it actually becomes more of a problem. The belt isn't so tight that it'll fall off easily. Instructions: 1: Take off the facebook QR sticker. 2: Remove the four screws and disconnect the motor from the connector. 3: Pull the motor and bracket off. 4: Take the two printed parts. Place the cylinder over the current gear. It should fit in place. 5: Add some superglue to the printed motor (on the side WITHOUT the edge). __From my experience, the gear MUST be placed on FLAT without any bumps/skewed sides or else the belt won't run across the gear correctly.__ 6: Slide it into the cylinder. Press firmly and keep it there for 10-20 minutes. 7: Remove the cylinder. It isn't needed anymore. 8: Place three to six washers (or an equivalent) on any of the two holes across from one another. 9: Screw in the motor damper to the motor. 10: Place the motor back inside the belt. Look and see if the belt runs smoothly. If not, add/remove washers as necessary. 11: Place the bracket back on. using two of the screws, attach the motor back to the bracket. 12: Re-connect motor and verify that belt isn't getting snagged. Re-tighten the belt if necessary.
