- Version compatibility and screw holes: Vyperr comes in four versions U Vyper-B, Vyper-C, Vyper-D, and Vyper-E. Vyper-B, Vyper-C, and Vyper-D have smooth, non-threaded screw holes. Vyper-E has threaded screw holes compatible with the Kobra4max series. Before ordering, confirm your printer model and screw-hole type to ensure proper fit. - Function and purpose: This strain gauge sensor is a replacement accessory for 3D printers. When the hot end mounting block and the induction strain gauge from a Vyperr model age fail or do not work properly, this part provides a reliable replacement to restore automatic hot-end stabilization and bed leveling. It is designed to work with the main board of the original printer model. - Installation and precautions: Easy to replace as part of routine maintenance or repair. Do not twist or bend wires at the welded area, as this can cause failure of the induction function. - Compatibility and performance: The part is intended to fix the hot end and level automatically, and it must be compatible with the main board of the printer’s original model for proper operation. - Quality and safety: Made from high-quality raw materials with good workmanship. Environmentally friendly, safe, and non-hazardous. - Use scenarios: 1) Replacing a failed induction strain gauge on a Vyperr B/C/D system to restore automatic bed leveling and stable hot-end positioning. 2) Replacing with a Vyperr-E version on a printer with threaded screw holes (such as those in the Kobra4max series) to ensure proper mounting compatibility. 3) Restoring auto-leveling and hot-end alignment on a printer where the original strain gauge or mounting block has degraded, while using only the printer’s original mainboard.
