I downloaded the latest update to CR-6 SE and for some reason, it did not have the CR-6 SE printer listed. I had to uninstall the latest and reinstall the version that came with the printer. I even tried the Ultimaker Cura latest version but it also did not have the CR-6 SE printer listed. I can only assume that the CR-6 SE is so new that the software has not been added.
The printer worked fine for me straight out of the box on my first print from the model provided. However, I tried another model with some strings on the model. I did notice that leveling should be done before each print. Not sure how I can fix it. The bed is not stable, but I am not sure if that is the problem..
