I have had the Lulzbot edition of Cura suddenly stop working on 2 different computers. One day it worked just fine, and the very next day the splash screen would load but after about 5-6 seconds it would just disappear. I have several computers in my home office so the first time it happened it was just easier to install on the next computer and keep going.
After this instance, I decided to upgrade to the latest version (3.6.25). I un-installed the previous version, cleared the cache files as recommended on the Lulzbot site, and installed the new version. I added the printer to Cura and went to test the connection and I get the error “Wrong printer detected” along with warnings about damage and being able to turn off this check in the settings.
The printer is on firmware version 184.108.40.206. I would greatly appreciate any advice anyone has and will also be happy to provide any additional information requested that’s needed (I am just not sure what else would be helpful at the moment).
Thanks very much,
