What's Included 1 × SparkX i7 leveling sensor Specs Type: auto-leveling / strain-gauge style nozzle-contact sensor Role: measures nozzle contact pressure for bed mesh and first-layer setup Mount: integrates with the SPARKX i7 hotend / toolhead assembly Compatibility: SPARKX i7, i7 Autofill, and i7 Color Combo Part number / SKU: 4001010043 Good To Know Used for automatic bed calibration so first layers land flat. Install per the SPARKX i7 leveling sensor replacement steps (toolhead access required). No manual feeler-gauge leveling is required once the sensor and mesh are working. Good For Fixing failed or inconsistent auto-level results Restoring first-layer reliability after a toolhead service Keeping a spare sensor for SPARKX i7 maintenance kits
