What is the problem?
When I try to print using the interface on the Ultimaker 2, I select Print option using the dial, and the contents of the SD card appear. As soon as I try scrolling through the list it selects the first file it goes over (when trying to scroll) and sends it to print on Octoprint. It means I cannot select the correct file to print.
What did you already try to solve it?
I don't really understand what has caused the problem to work out where to start to solve it!
Additional information about your setup
Effectively I was using the RPi to monitor the printing process and include the ability to cancel the print if I saw something going wrong. This used to work by connecting Octoprint to the Ultimaker 2, then sending a print job from the UM2. I was then able to monitor the print through Octoprint, and if I saw something going wrong from the camera feed, I could select the currently active job in Octoprint and cancel it. The problem described in the "problem" section, has become evident since moving from Rasbian with octoprint installed, to Octopi installed on the RPi. I used to be able to effectively print from the printer and monitor and control from the RPi.
I have an upgraded Ultimaker 2 (upgraded to 2+ with official kit) attached to an RPi B+ with an official camera attached and Octopi installed and Octoprint running. This is a recent change to how we were working (mentioned above), and it has not worked how it did since the change. It was changed because the RPi and octoprint stopped working, and wouldn't update anymore.
OctoPrint 1.3.10 running on OctoPi 0.15.1
Ultimaker 2 firmware _3.3.0
I hope this is enough information for someone to be able to assist.
Thank you in advance
