🔧 Installation Steps
Prep the Rear Panel: Remove the stock plastic vertical cable cover on the inside back wall of the printer

. This will expose the two horizontal factory slots/tabs built into the chassis.

Mount the Chute: Take your printed upgrade and slide it directly onto those two factory slots. It aligns perfectly with the toolhead path out of the box.

Re-calibrate Purge Coordinates: Because the position shifts slightly away from the Z-screw to a fixed chassis position, you must update your coordinates:

On your Creality screen, go to Settings ➡ Expert Mode ➡ Purge Coordinate Settings.
Manually align your toolhead to the new chute opening and save the new X/Y/Z coordinates. Done!
🖨 Recommended Print Settings
⚠ Material Requirement: ABS or ASA only. Do not print this in PLA. The internal chamber temperatures of the K1 combined with hot filament purges will deform PLA within days.

Orientation & Supports: Print it vertically as oriented in your slicer.

The design is largely support-free, but adding a single Tree/Organic Support under the main overhang is highly recommended to achieve maximum precision on the mounting tabs.
Print Time: ~35 minutes (optimized for high-speed coreXY profiles).
Layer Height: 0.2 mm
Wall Loops: 4 walls (mandatory for structural strength around the locking clips).
Infill: 15% (Gyroid or Grid).
