Hello

I have a Prusa every thing was working fine when I first tested the printer,
All the axis moved the right way, the LCD screen worked fine, so did the heated bed and the hot end.

This is where its gone wrong.....



I downloaded ARDUINO and starting looking at the configurations but i did not change any but I did press upload.

Now my prusa only moves in + direction on pronter face and the LCD screen had two line of white blocks and I can not work out how to fix it.

Hello,

If it only moves in the + direction, it is the problem of endstops seetings in the firmware. In my firmware, the direction to the endstop is the negative direction and without the endstop is the positive direction.
you should set again the firmware.
