When I click "Faind Z" to measure the Z axis, after the probe touches the workpiece, it looks like the picture and Mach4 stops.

Please tell me the solution.

The alert "ESS: Homing of axis completed successfully" pop out when probe hit work piece?

Hello.
When the probe touches the work　piece, nothing is displayed in the red frame.

Hi, you work with inches?
If you touch with hand the probe tip the probe led work as it suppose?
With G31 the probe led must turned on, not probe1 or probe2. Make sure at configure/control/inputs/probe is set the input of your controller.

Hello.
I have confirmed now.
I set it as shown in the picture.
-For the probe, a switch is connected to the input terminal (probe) and the probe is operated by turning it on and off.

-The unit is mm.

・ Please see the photo. The two LEDs turn on as shown in the red frame.

-I confirmed the controller input with configure / control / input / probe. Please look at the photo.

I'm passing, but I'm currently using Nach4 DEMO.
Is this the cause?

No, demo shouldn't affect the use.

Change the settings/options at TouchOff UI to metric units like Retract Distance if is 0.1 do it 5 and Prep. Distance 0.5 to 15

Are you sure your probe work ok?
Is homemade/DIY? 

Thank you.

> Distance 0.5 ~ 15

Is it okay to change the red frame in the photo?
I set the inside of the red frame to 0.5, but the problem is not solved.

It's DIY.

That's the distance when probe hit material will lift away. Means that will retract 0.5mm, i would had this more like 5mm if is for simple height measure or z offset.

If you can, try with simple cables in probe input of your controller and simulate the probe movement, if it work means that is probe problem and not software (Mach4).

Thank you.
I'm using MB3.
Please tell me the solution in this case.
