无法连接到AT960 pythonn激光跟踪器et-sig.johnnson-02-23-2023

I am not able to connect to an AT960 Laser Tracker using the RoboDK GUI.

When I click "Connect" in the "Laser Tracker System" pane, I get the following message in the "Laser Tracker Status log":

RE: UNABLE TO CONNECT TO AT960 LASER TRACKER-Sam-02-23-2023

I think pythonnet released a major version and the batch script doesn't take version range into account.
Can you try with pythonnet 2.5.2 or earlier?

C:\RoboDK\Python37\python.exe -m pip install pythonnet==2.5.2

I'll check with Albert for the specific version, and we will ensure it is working with the latest version too.

Hi Jeremy,

That solved the problem. Thanks!

Sam,

I am reopening this thread because I encountered another issue (on a different machine) when attempting to apply this fix.

Code:
C:\RoboDK\Python311>python.exe -m pip install pythonnet==2.5.2
收集pythonnet = = 2.5.2
Using cached pythonnet-2.5.2.tar.gz (1.9 MB)

Requirement already satisfied: pycparser in c:\robodk\python311\lib\site-packages (from pythonnet==2.5.2) (2.21)
Installing collected packages: pythonnet
DEPRECATION: pythonnet is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

This new machine runs Python 3.11.1, which I believe caused the issue.

I would like to continue using 3.11.1 because all my other code is written for 3.11.1 and match case is awesome. Is there a workaround for this besides switching Python versions to 3.7.3?

RE: UNABLE TO CONNECT TO AT960 LASER TRACKER-Albert-03-07-2023

Did you try installing the latest version of Pythonnet?

Just remove the version from the install command:
Code:
python.exe -m pip install pythonnet


RE: UNABLE TO CONNECT TO AT960 LASER TRACKER - pythonnet-Sam-03-07-2023

As specified on PyPI, pythonnet 2.5.2 only goes up to Python 3.8:
https://pypi.org/project/pythonnet/2.5.2/

I tested with pythonnet 3.0.1 this morning on Python 3.11 and did not get the crash in the driver.
Using pip freeze, I am using
clr-loader==0.2.5
cffi==1.15.1
pycparser==2.21

Albert, I tried removing the version from the .bat and still have this issue.

Sam, it looks like I have the same versions as you, but unfortunately, I am still encountering this problem.

RE: UNABLE TO CONNECT TO AT960 LASER TRACKER - pythonnet-Sam-03-07-2023

The Leica driver that ships with the RoboDK installer is more recent than the one//www.sinclairbody.com/downloads/private/Leica.zip.
Albert will update the link soon, but you can install update RoboDK in the meantime to get the latest version (located in C:\RoboDK\api\Leica).

RE: UNABLE TO CONNECT TO AT960 LASER TRACKER - pythonnet-sig.johnnson-03-07-2023

I downloaded a new version of RoboDK and grabbed the .bat, .dll, and .py out of the api/leica folder. This changed what error I was getting, but did not resolve it:
