Duet3D's Delta Smart Effector v4.0 allows the hotend to be used as a Z probe. It ensures excellent accuracy over the entire print area and eliminates the tilting effect. The Smart Effector comes with a custom e3d v6 heatsink and 3 PCB carriage adapters with a mounting hole spacing of 20mm. 1 hotend heating cartridge can be connected to the screw terminal on the bottom of the board (max. 5A). The built-in print lighting LEDs are compatible with 12V or 24V power supplies with a jumper that selects the voltage. This Delta Smart Effector is compatible with Haydn Huntley's MagBall delta arms.
