Tired of twisting bed leveling knobs before every single print job? The 3D Touch Auto Bed Leveling Sensor is an open-source clone of the classic BLTouch sensor, designed to make your FDM 3D printing experience completely hands-free. Utilizing a physical, solenoid-driven push-pin, this high-precision sensor physically probes multiple matrix points across your heated bed to calculate the exact tilt of your printing surface. Your printers firmware then dynamically adjusts the $Z$-axis height in real-time while printing, preventing nozzle scrapes and corner lifting.
Universal Bed Compatibility: Unlike inductive sensors that only detect steel, the physical touch pin works flawlessly on Glass, PEI, Aluminum, Tape, and Magnetic Sheets.
Ultra-Precise Repeatability: Delivers a standard deviation precision of roughly $0.01ext{mm}$, ensuring identical first-layer squish across every quadrant.
Intelligent Self-Test: The sensor automatically cycles its pin up and down upon power-up, flashing its internal LED to signal that its internal optical sensor is fully functional.
Compact & Lightweight: Easily mounts onto standard MK8 or V6 extruder shrouds without adding noticeable moving mass to your X-axis carriage.
