So, basically in every menu I go the feature selected will start going up and down in values by itself. In attached video you can see the bedtemp going up a down by itself and also the feedrate (printer was idle at the moment of recording). But this is for every menu (move, probe offset,...) and already made my bed crash into the nozzle while performing the probe offset. The moment I go in the move menu my X-axis starts going left and right. I also noticed the marlin mode does nothing. What I already did:
* reflash firmware
* clean screen and did a screen calibration
* checked the wiring for the screen
Anybody got the same problem or a solution?
