auto zero sensor

To make the automatic zero on the part, I have a simple printed circuit board.

When testing with the "Probing" script, I see that the value of the tool changes.

I do not use T or H in my code.

I only need that once the two touches have been made, it goes up to 20mm, discounting the thickness of the plate.

Thank you so much.

You need a different macro.

Instruction :

# 17:58 10-3-2020 Edit Wojtek
# The macro is intended for mobile tool length (cable) sensors.
# We are talking about pressure sensors (with a spring and a micro switch) or touch sensors (common board) placed on a material.
# In the case of touch sensors, remember that there is such a thing as a braking distance (ramp).
# It is therefore not recommended to use too high measuring speeds with this type of sensor.

# In case of a failed measurement (no material detected at "Maximum_distance" or the sensor was already active at the time of measurement), the Z-axis returns to the point where the measurement was started.
# If the measurement is successful, the Z axis goes to "Parking_position."

# After starting the measurement, please wait patiently for the console message " - - - - - - - - Probe End - - - - - - - - -".
# Until it appears, do not place your hands in the machine's working area.

Sensor_height = 10 # Height of the pressure sensor or touchpad
Probing_vel = 200 # Probing speed
Return_vel = 500 # Returning speed
Distance = 20 # Maximum measurement distance
Parking_position = -1 # Parking position after measurement (machine coordinates)
