Essential for 3D Printing: This strain gauge sensor is a crucial replacement part for 3 Combo. If your original heatbed leveling block or strain gauge malfunctions, this accessory ensures your 3D printer remains operational, maintaining and efficiency in your printing projects. Hassle-Free Installation: Designed as a direct clone of the old, this strain gauge sensor can be installed effortlessly. Simply remove the defective unit and replace it with this one. Note: This part is not compatible with for 2 Max, for 3 Max, or for K3MC models. Advanced Sensor Technology: Strain gauges are sophisticated sensors that transform mechanical strain into electrical signals. When attached to a 3D printer's heatbed, they measure strain and stress distribution under load, aiding in the assessment of material strength, stiffness, and durability, thus enhancing printer safety and reliability. Versatile Compatibility: While specifically designed for 3 Combo, this strain gauge sensor is also suitable for various other machines. It can be used with components like hot end fans, extruder heatsinks, gears, small motors, nozzles, and even aids in managing filament storage racks and print beds.
