P1 P1S nozzle cleaning Using the same brush head as the A1

The P1S factory wiper consistently failed to completely remove residual filament from the nozzle, impacting first-layer adhesion.

Therefore, I modified the wiper, utilizing an A1 wiper instead.

A1 wiper dimensions: 37mm * 8mm, 4mm thickness

The factory's three-screw fastening provides superior stability.

This significantly improves wiping efficiency.

The simplified version boasts a shorter print time.

During assembly, secure the three screws on the bracket before affixing the wiper component.

Attaching the wiper first will result in its destruction, due to an underlying screw requiring prior installation before wiper attachment.

Before attaching the wiper, briefly heat the adhesive surface with a lighter for enhanced adhesion.

If the A1 wiper is not genuine, the adhesive may not bond securely; consider using PET double-sided adhesive.

On May 6, 2025, I removed the full-length wiper version; the half-length variant performs better. Subsequently, I added a baffle to the half-length wiper, along with an aesthetically enhanced cover and a retraction-plus-wiper version.
