Klipper 3D Printer Servo Armed A1 Nozzle wiper

In Action: 

Added Additional screw holes to secure the system to a flat surface.

Added screw holes to secure the Servo motor.  Use M2.5x15mm screws.

Purchase Servo from here (AGFRC B13DLM V2 4.5KG) : https://s.click.aliexpress.com/e/_okWuwF7

Use M3 Square Nuts and M3 x30mm screws to fix the servo slider, servo and the servo bracket to the base.

Use Bambulab A1 Nozzle wiping Pad.

The Wiper Arm Model is split into 2 Bodes if you need to Lengthen it Or you can use the arm from the Original Printables Model.

In Klipper Config / .cfg file use the following: (This is for BTT Octopus Pro).

To Move the servo arm, just type “SET_SERVO SERVO=wipeServo ANGLE=115” In the console to change its angle. Change the 115 Number to desired Number.

!!!!Only use my Print _Start Gcode macro as a Guide to adjust yours.!!!

Add servo info: 5v 1.2 Amps minimum. If you want max speed and torque, 8.4V and 2Amps.

pin: PG13 ( your mainboard pin, i use estop port on my octopus pro, THE PORT NEEDS TO SEND 5V GND AND Signal)

Add a gcode macro:

[gcode_macro CLEAN_NOZZLE]
gcode:

G1 X45 F6000
G1 X10 F6000
G1 X5 Y104 F6000  ; Custom position after wipe
SET_SERVO SERVO=wipeServo ANGLE=0  ; Move servo back to 0 degrees
G4 P1000  ; Wait 1 second to ensure servo moves before finishing
#SET_SERVO SERVO=wipeServo WIDTH=0
#[gcode_macro CETRACT_WIPER]
