Port Probe does not work

Mihey18

Good afternoon. Please help with (Probe). Controller DDCSV 2.1. Firmware 2019-06-06-111. Connected to GND. When closed, the signal does not pass. There may be problems with the input on the controller itself. How to programmatically reassign the incoming signal from the Probe input to the Z limit (since it is not used)?

Sorry, but is it worth the wait?

Good day. Thanks for the detailed answer and desire to help. I updated the casing. Settings did not go wrong. Problem still exists. I will solve it in the simplest way - I will replace opto-isolation with a new one. Most likely, opto-isolation is out of order during commissioning. Thanks a lot again.
