LCD on my k8400 blinks sometimes

Vertex 3D Printer Vertex - Parts issues

Hi!

I’ve just assembled my K8400 printer. Everything works well. The one thing is interesting for me. During the printing my LCD sometimes blinks (display text disappears for a microsecond). Is it normal behavior?

Regards,

Hi, mine does the same, but only when I use Repetier, but still prints ok, I normally use Simplyfi and that is fine. Ted

I use Repetier also. It seems to be working as designed. I just wanted to make sure.
Thanks for reply

You might try reseating the connection between the LCD and SD board.
If this doesn’t work try it without the stand offs.
If that works then maybe shave just a little off of each stand off
