Bambu Lab Style Nozzle Wiper 2020 Extrusion

Bambu Lab Nozzle Wiper for 2020 Extrusion

 

Update 060123: 

1.  Redone the rounding between base and arm
2. For better stability i added another STL with two holes, so the wiper can't rotate anymore.
   In future updates i'am planning to add a magnetic poopbox, but this will rise the base.

 

Print:

• ASA or ABS (heated chamber)
• PETG (open/cold chamber)
• Voron Specs
• print flat on the back with Brim Ears

Additional hardware:

• M3x20 Screw
• M3x8 Screw
• M3 T-Nut
• Silicone Tubing 6mm OD - 3mm ID, ~14.5mm long

The M3x20 comes into the finger with the little 45° notch and screws directly into the plastic in the rectangular finger. DONT overtighten, otherwise you will notice the whole swiper to bend to one side.

IF you use a Voron V2.4 you might need to move the bed 5-6mm forward.
Then you need to update your printer.cfg with:

[stepper_y]
...
position_endstop: 356
position_max: 356
...

TEST THE COORDINATES OUT BEFORE RAMMING INTO ANYTHING!

 

Macro for Klipper, which needs the position of your installment:

[gcode_macro SWIPE]
variable_start_x: ##YOUR X POSITION##
variable_start_y: ##YOUR Y POSITION##
variable_start_z: ##YOUR Z POSITION of the Nozzle a bit lower##
my location, but i moved the bed 6mm forward
#variable_start_x: 80
#variable_start_y: 355
#variable_start_z: 9

variable_wipe_dist: 20
variable_wipe_qty: 4
variable_wipe_spd: 200
variable_raise_distance: 10
gcode:
 {% if "xyz" not in printer.toolhead.homed_axes %}
   CG28
 {% endif %}
 G90                                            ; absolute positioning
Move nozzle to start position
 G1 X{start_x} F6000
 G1 Y{start_y} F6000
 G1 Z{start_z} F1500
Wipe nozzle
 {% for wipes in range(1, (wipe_qty + 1)) %}
   G1 X{start_x + wipe_dist} F{wipe_spd * 60}
   G1 X{start_x} F{wipe_spd * 60}
 {% endfor %}
Raise nozzle
 G1 Z{raise_distance}
 G1 X175 Y175 F6000
[gcode_macro CG28]
gcode:
 {% if "x" not in printer.toolhead.homed_axes or "y" not in printer.toolhead.homed_axes or "z" not in printer.toolhead.homed_axes %}
