Ender 3 X-axis stepper motor damper mount for press-fit pulleys

myminifactory

This model enables mounting a stepper motor damper on the X axis, provided the motor features a press-fit pulley that cannot be removed without risking damage to the motor. Printing a simple stop flag or a mount for an M18 sensor becomes possible, with the distance being measured from the nozzle as X +48. To complete the assembly, you will require the following fasteners: two M3x25 screws, two M3x20 socket head screws, two M3 nuts, and six M3 washers (although not strictly necessary, they are recommended for added stability). It is crucial to have a bootloader and an editable version of the firmware installed prior to commencing the assembly process. Due to the motor being assembled in reverse, it will rotate in the opposite direction. To rectify this, modify the value of #define INVERT_X_DIR in the firmware. Alternatively, you can alter the motor direction by swapping wires within the connectors; however, be cautious and aware that doing so poses a risk of damaging your circuit board. If you are unsure about these procedures, it is strongly advised to seek guidance from an experienced individual or avoid making such modifications altogether.
