Simple: The 3D Press can be easily applied thanks to its compact size and simple design. Collecting information and configuring firmware will be a straightforward task. The 3D Press works normally to automatically calibrate sensors on the bed. Smart: Self-test: press the pin three times to test. Power alarm: LED indicator blinks if an issue is detected during self-test or operation. High precision: The repeatability standard deviation of the 3D Press is approximately 0.005 mm, ensuring precision. Choosing the 3D Press will make your 3D printer a masterpiece, giving you a pleasant experience. Innovative electromagnetism: ultra energy-saving in standby mode, and when the sensor detaches or retracts, there's no magnetic valve for current flow. The standby current for the entire unit is less than an average of 15mA, in operating mode, when you step on it, suddenly at around 100ms, the unit under 300mA current flow. Low power consumption further reduces Joule heating, avoiding thermal issues. Bed width selection: The 3D Press does not use light and is not close to the sensor (inductive/capacitive). The 3D Press offers high precision through Hall-effect control. Therefore, bed material can be chosen freely. Installation precautions: 1. Do not connect reversed +5V and GND. If connected for a long time, it may burn out. 2. Install as far away as possible from strong magnets, motors, fans, and other magnetic components. 3. Unintended interference with the sensor's aluminum rod may damage or affect detection accuracy. 4. To adjust or install the sensor's adjustment screw, apply thread lock. 5. Install the sensor to avoid deformation of the housing. 6. Pulling hard on the aluminum rod may damage or affect detection accuracy.
