I connected a reprapdiscount smart LCD to my MPCNC (I admit I didn’t source it from vicious1, couldn’t stand another battle with UK customs).
After a while the image loses registration ( see photos). This happens:
after a variable time (minutes);
Whether powered by USB from laptop or vicious1’s supplied power supply; Resetting the ramps by pressing the button on the ramps side doesn’t correct it; Moving the display away from the ramps and ensuring its leads don’t pass near any obvious electric fields doesn’t stop it happening.
Removing power and then repowering corrects it for a while.
Is this a known issue with a fix, a faulty LCD display or ?
