Antclabs BLTouch Smart+ Levelling Sensor

The BLTouch Smart+ from Antclabs is a precise levelling sensor that enables automatic bed levelling regardless of the printing surface (glass, bluetape, etc.).

The BLTouch Smart+ is simple in design and can be used on almost any printer. It ensures high precision through the use of a progressively designed solenoid and Hall sensor. The sensor aims for ease of use and convenient printing by incorporating many smart features, including self-test, alarm, alarm trigger and touch switch mode, blue LED for servo signal indication and Z-Probe (Zmin) testing.

Easy installation

The BLTouch Smart+ has two wiring groups: One with three wires and one with two wires. The group of three wires is a standard servo connection and the group of two wires is a switch. The probe is controlled via the servo connection and extended and retracted as required. The switch informs the printer when the probe has touched the bed.

Note: You can find the exact function of the individual wires in the user manual. When installing on your hotend, make sure that the extended probe reaches under the nozzle, otherwise the probe will be unusable! Be sure to test this visually before attempting to use the BLTouch Smart+.

► Note that depending on your 3D printer, a firmware update may be required for the BLTouch Smart+ to function properly.
