Nozzle Cleaner for Ender 3 V3 SE (Klipper macro + instruction)

This is an improved version of the Nozzle Cleaner for the Ender 3 V3 SE (A1/A1 mini combs) , optimized for easier use and compatibility with Klipper firmware. This cleaner works efficiently with silicone combs to maintain a clean nozzle during prints.

🧽This macro is designed to clean the nozzle using a silicone comb . It uses a center-based approach , followed by a zigzag motion to ensure thorough cleaning.

🖨 Print settings: 🔷Material: PETG

🔷Layer height: 0.2 mm

🚀! No supports required

🤖 Install the Macro:

✅Copy the WIPE macro into your marco.cfg file on Klipper.

📝Adjust the parameters, such as the comb's center ( comb_x , comb_y ) and width, based on your specific setup.

✅Go to center comb

✅look at the coordinates in the klipper

✅ write them into a macro

✅add WIPE in your PRINT_START
