Ender 3 Pro Overhaul

A heavily modified Ender 3 Pro optimized for reliability and precision. Key upgrades include a BTT SKR Mini E3 V3 mainboard and a Sherpa Mini direct drive extruder for improved filament control. To ensure consistent first-layer accuracy, the machine features auto-bed leveling (ABL) and upgraded high-torque X/Y stepper motors. The system is controlled via a Raspberry Pi 3B running Klipper.
