Ender 3 Pro Y-axis Damper for press fit steppers

thingiverse

I found that my Ender 3 pro has press fit pulleys on the X and Y axis stepper motors. I didn't want to damage them by trying to remove them and I wanted a better way to fit dampers on. I created this print so that I could use all the parts already included with the Ender and not have to buy any additional hardware or relocate any endstops. Steps: 1. Print part 2. Remove X and Y steppers 3. Be sure that Y stepper is longer (if your stepper shafts are equal height then this mod won't work for you) 4. Install dampers on both motors 5. Install longer shaft motor on x-axis (re-use 2 black 40mm bolts and the plastic cover with endstop) 6. Install shorter shaft motor on y-axis using printed part to line up the belt (use the spare black M3 40mm bolts from x-axis cover) 7. Change your firmware to invert Y-axis OR do what I did - rewire the y-motor plug -This is a simple process if you have a very small flat head screwdriver or even a sharp knife would do the trick. The stepper motor has a 6 wire plug we'll call them positions 123456. Slots 2 and 5 don't have wires so should look like: 1-34-6. Just swap all wires with it's opposite - so new wiring should be 6-43-1. -Simply lift the small white plastic square enough to remove the wire (see photo) and press it into it's new home.
