Ender 3 wiper brush holder

thingiverse

These are wiper brush mounts specifically designed for the Ender 3. They attach securely to the two bolts located on the right side of the X-axis, requiring no modification whatsoever to the printer itself. The only difference between these mounts is their orientation, but they can both be printed without any support structures. The brush needs to be carefully glued onto the part. The wiper brush moves in tandem with the Z axis and can be utilized on any layer. This means it's incredibly versatile and can be used across multiple printing projects. For those interested in using this feature, a specific brush is recommended: https://www.aliexpress.com/item/32717622692.html. When positioning the brush, aim for around 235 to 249 on the X-axis for optimal results. To take full advantage of this feature, you will need to enable wiping in Marlin 2.0 and use G12 commands to wipe. For a visual demonstration of how G12 works, check out the following videos: https://www.youtube.com/watch?v=fycvtZrwkFU https://www.youtube.com/watch?v=syfyJmdJV2U Here is some sample code for Marlin 2.0 to get you started: ```c #define NOZZLE_CLEAN_FEATURE #if ENABLED(NOZZLE_CLEAN_FEATURE) // Default number of pattern repetitions #define NOZZLE_CLEAN_STROKES 12 // Default number of triangles #define NOZZLE_CLEAN_TRIANGLES 3 // Specify positions for each tool as { { X, Y, Z }, { X, Y, Z } } // Dual hotend system may use { { -20, (Y_BED_SIZE / 2), (Z_MIN_POS + 1) }, { 420, (Y_BED_SIZE / 2), (Z_MIN_POS + 1) }} #define NOZZLE_CLEAN_START_POINT { { 235, 100, (Z_MIN_POS + 1) } } #define NOZZLE_CLEAN_END_POINT { { 249, 100, (Z_MIN_POS + 1) } } // Circular pattern radius #define NOZZLE_CLEAN_CIRCLE_RADIUS 6.5 // Circular pattern circle fragments number #define NOZZLE_CLEAN_CIRCLE_FN 10 // Middle point of circle #define NOZZLE_CLEAN_CIRCLE_MIDDLE NOZZLE_CLEAN_START_POINT // Move the nozzle to the initial position after cleaning #define NOZZLE_CLEAN_GOBACK // Enable for a purge/clean station that's always at the gantry height (thus no Z move) #define NOZZLE_CLEAN_NO_Z #endif ```
