Cura 5.1 build plate empty after file open

Posted · Cura 5.1 build plate empty after file open

I have been using Cura 5.1.0 on Linux fine for a while now but today when I open a STL file or prior project the build plate is empty, then is nothing to slice.  I have not changed anything that I am aware of that would affect the operations.

 

When starting from the command line I see these messages:

 

david@kobo:~/Dev/lcd4linux/ax206case$ Ultimaker-Cura-5.1.0-linux.AppImage
PyInstaller/loader/pyimod03_importers.py:495: DeprecationWarning: the imp module is deprecated in favour of importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses
Cyclic dependency detected between "file:///tmp/.mount_Ultimad26iae/share/cura/resources/qml/Actions.qml" and "file:///tmp/.mount_Ultimad26iae/share/cura/resources/qml/Actions.qml"
QQmlEngine::setContextForObject(): Object already has a QQmlContext

 

There are no messages or warning when I open files.

 

I tried deleting ~/.local/share/cura folder to reset everything but that did not help.  Not sure what other info I need to provide or what other steps I can try?  Any suggestions would be welcome

    Well, it appears to have loaded after a long delay.  There was no feedback that anything was happening, I just notice after writing this the build plate had populated.  Opening it again I see it has taken about 4 minutes for the "Open Project" dialogue box to appear.

     

    I have found the cura.log file, attached is a trimmed version to show from start up to build plate population.  I am seeing a lot of messages such as:

    I guess it probing for printers.  My printer is networked via Octoprint, the devices it is probing are embedded devices I am doing development work on and I would rather not have probed.  One change since last running Cura is I have STM32F746-Disco devkit attached via USB which may be answering probes.

    I finished work with the STM32F746-Disco devkit so have disconnected it and have since used Cura with no problems.  So it does look like there is a bug or an undesirable interaction in play.
