I have a Creality Ender 3 Pro with Octoprint installed. Octopi gives me access to the printer wirelessly-maybe that is my downfall.
When I try to connect to the printer using the IP address within S3D, it gives me a connection error, although I have username, password, etc, all entered.
I can connect to the printer via browser, so I know the link is working. I can see on the touchscreen that the RPi is working, so not sure why I can't control the printer through S3D. Too many things for the app to go through? Looked for this topic, sorry if it was already discussed...maybe my search terms were wrong.
