Adding to the question of Cura's backward compatibility debate, I too am having issues whilst using Cura 4.13.1
After slicing an STL file, previously used in2018 successfully, the G-Code details show the following message:
"Make sure the g-code is suitable for your printer configuration before sending the file to it. The g-code representation may not be accurate."
The model is then shown in red and cannot be selected, modified or moved.
Before resuming 3D printing in 2022 I was successfully printing these models on a previous version of cura. Can you confirm that it is NOT the installation of the latest version of cura that is causing this issue and give me some guidance on what it could be?
If I need to install an old version of Cura, can you suggest which release I should try?
Thank you
Best regards
David
