What is the problem?
The UI on my Ender 3 v2 is showing as corrupted whenever I turn the printer on with my Octopi already connected. No loading bar is shown when the printer is turned on, and the display doesn't seem to update unless I try to navigate around the menu. When I do, many of the options are shown as corrupted icons.
Another thing I am seeing is that when the printer is turned off at the PSU, having Octopi connected will result in either the printer display flashing on and off (black screen powered / not powered), or one of the hotend fans will repeatedly try to spin.
None of these issues occur if I connect Octopi after the printer has been turned on.
What did you already try to solve it?
- Reinstalling / reflashing Octopi
- Installing latest Marlin firmware on Ender 3 v2
- Use different power supplies for the Raspberry Pi
- Use different cables for the Pi -> printer connection
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
