Great news! Quite some hours getting this to work on the RPi in Pi OS. It's been working for ages in Arch Linux....

Just had the time to test this out. This is way better now scotta! Thank you very much!! The axis backplot still feels a little bit snappier (especially when rotating the view) But it is good enough for me to switch over from axis.

Does the ATC tab in probe_basic work for you guys? It does not show anything for me (in the sim as well as on my own machine). I don't really mind it not working since i am manually changing tools but i think it not working is messing up my tool screen and tool database.

the atc tab ist perfect for umbrella or side mount tool changers.
I like the widget, with a litte bit of work it can be adopted to different types of tool changers. I am working with a basket tool changer and modified my tool change code to detect if a tool is in the toll changer or If I need to manually change it.

I made the adjustments to suite my needs and really loving probe_basic.

I'm trying to get VTK to work on a Rpi4 with Raspian Lite and Openbox mainly because the desktop OS's change the colors of widgets to match someone's style in some far off place I guess.

Anyway I downloaded the deb and did dpkg -i and got this error.
$ sudo dpkg -i vtk_7.1.1-qt5py2-1_armhf.deb
[sudo] password for john: 
dpkg-deb: error: 'vtk_7.1.1-qt5py2-1_armhf.deb' is not a Debian format archive
dpkg: error processing archive vtk_7.1.1-qt5py2-1_armhf.deb (--install):
 dpkg-deb --control subprocess returned error exit status 2
Errors were encountered while processing:
 vtk_7.1.1-qt5py2-1_armhf.deb

Do you have the steps you used to build the deb?

Don't execute "wget github.com/scottalford75/LinuxCNC-on-RPi...1-qt5py2-1_armhf.deb"
You will end up for some reason with a incomplete downloaded file.
Try to download the link github.com/scottalford75/LinuxCNC-on-RPi...1-qt5py2-1_armhf.deb with a browser

Hi scotta,

i´ve tried to install probe basic on RP4 with your deb file but i still have the

ImportError: No module named qt

error.

Do you know a solution on this issue?

Thanks in advance.

Best regards,

Nic

Does qtpyvcp load the simpler QUI's? Looks like a basic config error and nothing to do with the VTK back plot.

Hi scotta,

thank you for your reply. No, none of the qtpyvcp UI`s work.

Best regards,

Nic
