From the project

This repository contains the Shecmatic and PCB design for a timer circucit providing 24v backup power to a 3d printer hotend fan in the even tof power loss during printing. This is aimed to reduce the chances of heat creep that can cause filament tp swell in the heatsink passage and cause clogs and jams inadvently

A KiCad PCB design for a timer circuit that provides 24 V backup power to a 3D printer hotend fan in the event of a power loss during printing. This prevents heat creep — the condition where residual heat travels up into the heatsink passage, causing filament to swell, clog, or jam.

When a 3D printer loses power mid-print, the hotend heater turns off but residual heat remains in the heater block. Without the cooling fan running, this heat can creep up the cold zone, softening and swelling the filament inside the heatsink passage. The result is a jam that requires manual disassembly to clear.
