It starts looking like hieroglyphics sometimes. It's not every time but it starts messing up after I hit print.
It's not octoprint's fault.
The display cable got no shielding so that can happen from time to time.
There are several options:
- shield the cable
- use a ferrit bead
- route the cable as far away as possible from components that generate electro magnetic interference
- press the center button to refresh the display when it happens
