LCD resets / blanks out when I touch the Ground
January 09, 2016 06:21AM
I spent so much time trying to figure this out but every attempt failed.

When I switch on my printer:

• The menu on the LCD shows nicely
• Bed and Nozzle heat up OK
• XYZE move ok
• It can print with no issues

… however …

When I touch my nozzle, printer body (metal) or Ground with my tweezers, the LCD goes blank (light still on).
If it is in a middle of a print it will continue if not, pressing the rest button recovers the OS. Sometimes the LCD Menu corrupts, then I need to restart.

Another point … when I disconnect all peripherals but the LCD, it does the same when I touch the ground.

Please help! confused smiley
