I was measuring the voltage of stepper drivers with multimeter and suddenly computer shut down and LCD turned out totally white.
I think I probed somewhere else by mistake which caused that.
The current state is:
- If the Ramps is connected only to computer,
- LCD Screen works fine,
- Can see SD card,
- Able to move axies from Repetier Host and can see the changes on the LCD screen.
- If I also connect the system to means voltage,
- Computer shuts down immediately,
- Screen turns out white
- I can make it visible again by playing with the LCD backlight potentiometer
- Steppers does NOT move when playing from Motion menu.
- Cannot see SD card.
- Ramps 1.4 Shield - Elecfreaks
- Arduino Mega - Clone
- Pololu DRV8825 High Current Stepper Driver
- 12V-5A Switch Mode power supply > Measured it with multimeter and works fine.
