Error: Checking the trigger height
-
If I follow the instructions "Checking the trigger height" step by step, I get the error: "Probe already triggered at start of probing move" at the step with the command: G30 S-1, although I did the first steps M561 and M564 S0 entered. What can be the reason?

Have you done the static and dynamic test of the probe to verify it's working first?

Probe already triggered may mean the input pin needs to be inverted, or the probe wiring is incorrect, or the probe has a fault, or that it's actually already in a triggered state. You'd need to provide a lot more information to determine which it could be.
