External stepper motor driver board panel additional adapter A4988/DRV8825

This z-probe is developed for 3D printer leveling. As an external leveling sensor, it directly triggers from the nozzle, which greatly improves the printing platform accuracy. The leveling effort is much better than probe type, inching switch type, Ohmic proximity switch type and steering gear type.



Working with indicator panel, the super light will light up when the z-probe triggers. It’s more controllable.
The connection of indicator panel
Set Z Mini “Always-on” on the firmware. it’s not allowed to operate with power on, otherwise, the controller board and indicator panel would burn out. Wrong wire connection would have the same result.
The use of Z-Probe sensor with indicator panel
The Z-Probe can’t afford the high temperature, so it can’t be used until the nozzle drops to room temperature.
