Ender 3 Pro Damper Spacers

thingiverse

This is a remix of the damper spacer by matthijsp (https://www.thingiverse.com/thing:3245255), designed for the Ender 3 Pro. You only need to print the one file provided in this remix for the printer and you can re-use most of the original Ender 3 Pro hardware. __You will need the following additional hardware:__ 2x M3x25mm screws* 2x M3 nuts 2x M3 washers (optional) **Longer screws are possible, but you will need to space them using M3 nuts and/or washers (see my pictures)* 1. Switch off and electrically disconnect Ender 3 Pro 2. Disconnect X and Y axis stepper motors and limit switches 3. Remove screws holding X and Y axis stepper motors (take care not to drop them) __NOTE: Set aside all screws for reassembly__ 4. Attach stepper dampers as per image with the original M3x6mm screws __NOTE: Swap stepper dampers so that the X axis motor goes on the Y axis and vice versa__ 5. Attach X and Y axis dampers as shown, using the M3x25mm screws and nuts to secure the Y axis and the original fasteners to secure the X axis 6. Flash a new firmware with the Y axis inverted (Refer to this video: https://www.youtube.com/watch?v=IjzrNoFnbcI) 7. Remove the bed and Y axis carriage, flip it upside-down (so the wheels are on the other side) and then reattach the carriage __NOTE: The Y axis carriage is asymmetric. There is a cutout on one side so that it doesn't contact the stepper motor. Refer to the picture if you are unsure__ 8. Perform an eccentric nut adjustment on the Y axis and reattach the bed 8. Reconnect all stepper motors and limit switches 9. Reconnect the Ender 3 Pro and test that the steppers move in the correct direction
