Probe interface problem

good morning
since update 1.57 the probe no longer works.
I work with the black box 4 and the interface
the bet went well but since then the probe via the interface no longer works.
here is the error I have on the interface screen:
GRBL error
Error n2
numeric value
Not valid

I tried to make the probe with the black box directly and it works
Everything is up to date

can you give me solutions to my problem?

Thank you

 

ok but interface or Blackbox X4?
thank for your answer

 

Ok I just did the manipulation and it does not solve the problem
here is what i do
I will look for the file in the PROBE folder
I select ¨ROBEXYZ PRB and nothing happens
I cancel and strangely I can launch the sequence like a machining program
but as soon as he touches the probe he gives me the error

firmware interface black box 1.57
openbuilds controle 1.0.344

 

I made a mistake in my way of launching the probe sequence I am really sorry because in fact it worked very well from the beginning

all my excuses

 

thank you for your answers
