Ender 3 - Y-Axis Stepper Damper V2

prusaprinters

When I originally ordered my Ender 3, I also purchased a few stepper motor dampeners. To my dismay, the stepper motors had press-fit pulleys, preventing me from being able to use most of them. My previous design worked very well, but it was a little more complex than I liked. This is a completely new design that's much cleaner and easier to install! This design reuses the existing stepper mount plate and screws. It also doesn't require any fiddling with the end stop.NOTE: Does not work on the Ender-3 ProAlso, check out these other mods that dramatically reduce the sound of your Ender 3X-Axis Stepper DamperZ-Axis Stepper DamperLow Profile FeetEnjoy the silence...Print SettingsSupports:NoResolution: 0.2Infill:40% Notes: 3-4 Wall Lines4 Top/Bottom LayersPost-PrintingRequired:1 x NEMA 17 Stepper motor damperwith large inner diameter like this one2 x M4*16mm screws (optional)Steps:Power down printerRemove wires from y-axis stepper motor and end stopRemove the stepper motor screws (4 x M3*6mm)Remove the stepper mount plate screws (2 x M4*16mm)Test fit siding the printed mount plate adapters into the end of the y-axis(this will give you an opportunity to ensure the mounts fit flush) 6. Attach the stepper damper to original mount plate with 2 x M36mm screws 7. Attach stepper motor to stepper damper with remaining 2 x M36mm screws 8. Sandwich the original mount plate between the left and right printed mounts 9. Screw the printed mounts together with the 2 x M4*16mm screws(do not tighten fully) 10. Slide the mounts into the end of the y-axis 11. Tighten the M4*16mm on the mount, until snug(do not over tighten) 12. (Optional) Screw additional 2 x M4*16mm screws into the side of the stepper mount to improve stiffness 13. Loosen the belt tension assembly on the front of the printer(this will need to move approximately 2mm towards the printer) 14. Slide the belt over the stepper motor pulley 15. Making sure the belt is under proper tension, tighten the front belt tension assembly 16. Reattach stepper motor and end stop wire connectorsIt's a good idea to ensure the belt remains centered when moving the bed back and forth.  Category: 3D Printer Parts
