Attaching a layer of Teflon on the nozzle is not recommended as it may affect the printing quality and cause other issues. Instead, there are a few steps you can take to prevent residue filament from dragging along the first layer:
Adjust the nozzle height: Ensure that the nozzle is properly leveled and adjusted to the correct distance from the print bed. This will help prevent the nozzle from touching the printed part.
Clean the nozzle: Before each print, make sure the nozzle is clean and free from any residue filament. You can use a soft cloth or a brush to gently clean the nozzle.
Use a prime/wipe tower or skirt: You can add a prime/wipe tower or skirt to your print settings. This will help purge any excess filament from the nozzle before printing the actual model.
Adjust retraction settings: Properly calibrating the retraction settings can reduce the amount of filament oozing from the nozzle, thereby minimizing the chances of residue dragging along the first laye...
