bcnc : autolevel only zero in output

[clerfe]

Hello everyone
I"m new in your community ; thank you for welcoming me and I apologize in advance for possible mistakes.

My project is to transform a milling machine Proxxon MF70 into a CNC with Arduino and Shield CNC V3 GRBL.

My configuration on my computer is : Windows 10, Python 2.7,18 bcnc 0.0.14-dev.

All is perfectly working except the results of the autolevel** (my intention is to mill Printed Circuit Boards).
After clicking on the gear Scan button, autolevel is progressing well. For information, there are no offset data on the matrix when the probe is running, contrary to what I have seen on tutorials .

At the end, after selecting "ZERO" in the Probe Tab, there are only zero :

• on the image on bcnc
• and in the file probe as you can see below testing a very simple example :

-62.69 -3.35 5
-36.95 0.3 3
-2 0.6 2

-62.69 -36.95 0
-47.855 -36.95 0
-33.02 -36.95 0
-18.185 -36.95 0
-3.35 -36.95 0

-62.69 -18.325 0
-47.855 -18.325 0
-33.02 -18.325 0
-18.185 -18.325 0
-3.35 -18.325 0

-62.69 0.3 0
-47.855 0.3 0
-33.02 0.3 0
-18.185 0.3 0
-3.35 0.3 0

And last, I looked in the information in Terminal, there are offsets !

Thanks a lot in advance to anyone who can help me
