I bought a Cheetah v2.0 and have installed it on an Ender-3 Pro.
Previously, I had Cheetah v1.2 and was working without any issues.
I have stock display connected on the EXP3 connector. The screen light is powered up accordingly but nothing is displayed on it.
There is also some little moves from all axis.
Is there something to flash before using it?
Many thanks in advance!
