The following messages when starting from terminal:

rob@RobsCNC:~$ designer -qt=5
('Qtvcp python plugin found:', '/home/rob/.designer/plugins/python/qtvcp_plugin.pyc')

I seem to recall Chris mentioning this somewhere recently but I cannot seem to find it, hopefully he will chime in.

This printout is expected now - This is not an actual error.

Script has been updated with some files required for other distributions and should now work for both python2 and python3 installations.

I can confirm that there is no qt5.11 folder within /usr/lib/python2.7/dist-packages/qtvcp/designer/x86_64/

This is also fixed and now available on buildbot installs.

Did you get this working on Mint 20.1 , I can't install the script from the repo 'linuxcnc-uspace-dev package' because of uninstallable python-serial and python-yapps dependencies. (master branch).
Doing it manual doesn't resolve my problems either.

Axis works, but QTplasma refuses to work. Always get Qtvcp / Qtwidgets and QT-core errors. (On Mint 19.3 everything works.)

I'm new and just trying to convert my router to a plasma table with a mesa 7i96. I've got a long way to go..

I don't use use Mint so I can't help you there...

If you are new to LinuxCNC then it would be best to start with a known working distribution.

mint 20 requires linuxcnc to be compiled for python3.
I don't believe there is a buildbot version for python3

Python3 is not ready for prime time IMHO

Yeah, does not work on Mint 20, even after having 6 versions of python installed, it fails to import QT5 modules!
