Thingiverse part:https://www.thingiverse.com/thing:3154398I made a completely new bracket to fit my ratrig vcore 3 and also filled in some gaps in the original part. I then added a new servo in Klipper and added a macro to run the cleaning. The macro may need to be adjusted for the cleaning pattern and the z height to match your nozzle height.servo setup in printer.cfg:[servo Cleaner_Brush]pin: PD2maximum_servo_angle: 180minimum_pulse_width: 0.0005maximum_pulse_width: 0.0025Macro:[gcode_macro CLEAN_NOZZLE]gcode: #save current state SAVE_GCODE_STATE NAME=pre_nozzle_clean maybe_home # Absolute positioning G90 #check if z > 25 else move to 25 {% set act_z = printer.toolhead.position.z|float %} {% if act_z < (25) %} G0 Z{25} F3000 {% endif %} #move x,y to 0,0 G0 X0 Y300 F3000 #deploy brush SET_SERVO SERVO=Cleaner_Brush ANGLE=180 G0 x0 y260 F3000 G0 x5 y300 F3000 G0 x0 y260 F3000 G0 x5 y300 F3000 G0 x0 y260 F3000 #home x and y G0 x0 y300 F3000 #stow brush SET_SERVO SERVO=Cleaner_Brush ANGLE=0 #restore state RESTORE_GCODE_STATE NAME=pre_nozzle_clean
