Dmitry made a great model and supplied the Marco code for Klipper. I just made it work for the AI3M bed!

For macro setup, look back at Dmitry post.

Note: You may need to take off the bed to get it on.

description: Wipe nozzle on silicone comb (center-based + zigzag)

Comb parameters

variable_comb_x: 100. ; X center of the comb variable_comb_y: 223. ; Y center of the comb variable_comb_z: 4.00 ; Z when touching the comb

General parameters

variable_comb_z_lift: 5.0 ; Nozzle lift before/after wiping variable_comb_width: 40.0 ; Full width of the comb (mm) variable_comb_cycles_1: 4 ; Number of cycles in the first pass variable_comb_cycles_2: 3 ; Number of zigzags in the second pass variable_comb_offset_y: 1.0 ; Y offset for the second pass variable_comb_zigzag_shift: 1.5 ; X shift for each zigzag step

Return to specified position

variable_return_x: 100.0 variable_return_y: 20.0

gcode: {% set half_width = comb_width / 2 %} {% set zigzag_shift = comb_zigzag_shift %}
