Rather than relying on non-contact proximity or optical sensors, this module measures the minute mechanical deflection caused when the nozzle tip physically touches the build plate. This enables automatic Z-offset calculation and dynamic mesh bed leveling regardless of the bed sheet surface material (PEI, glass, textured steel).\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDirect Nozzle Bed Leveling: \u003c\/strong\u003eDetects physical contact force directly through the nozzle tip, completely eliminating manual Z-offset adjustments or offset errors caused by nozzle swaps.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eHigh Sensitivity Load Cell:\u003c\/strong\u003e Built into a flexible aluminum mounting bridge that reacts to micro-gram level changes in vertical pressure when probing the bed mesh matrix.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eUniversal Surface Compatibility\u003c\/strong\u003e: Works across all build plate textures and coatings (textured PEI, smooth magnetic sheets, garolite) without calibration shifts.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003ePre-Wired Interface Harness: \u003c\/strong\u003eComes integrated with high-flex lead wiring and a micro JST connector that plugs directly into the toolhead PCB board.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eCompatible Models: Anycubic Kobra S1 \/ Kobra S1 Combo.\u003c\/li\u003e\n\t\u003cli\u003eSensor Mechanism: Resistance Strain Gauge \/ Piezoelectric Load Cell Element.\u003c\/li\u003e\n\t\u003cli\u003eOperating Voltage: 3.3V \/ 5V DC (supplied via toolhead breakout board)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eMaintenance \u0026amp; Care Tips\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eKeep Nozzle Clean Prior to Leveling: Always ensure the nozzle tip is free of hardened filament globs before starting Auto-Bed Leveling (ABL).
