Reprap Discount Full Graphic LCD Controller - Blue Screen
July 18, 2025 03:33PM
Hi everyone!

I have a Full Graphic LCD Controller that starts blue screen after the print starts.
Before comanding the print, the screen shows the status normally.
Bul after the print starts, the blue screen appears.
Sometimes starnge caracthers appear at any moment.
Does anybody know how to fix this?
Thanks!

... can you measure the +5V for the controller, if it breaks down?

... there should be several pins, marked with "+5" and "GND" -- connect a multimeter and look, if the 5V level drops, if printing starts ... most likely with unsufficient current from the PS

Ok, thank you.
I understood.
But is there a way to keep the 5V level constant? Even after the printing starts?
I believe that this blue screen starts after the BLTouch pins down.
But even with the blue screen lighted, the printing begins and goes up to the end.
I am still asking myself how to keep this 5V level.

... if it's lack of current, then a "stronger" PS will help smoking smiley
