The jumpers his talking about are next to your reset button 3 pins, 2 front or 2 back be jumped.
2 front for firmware threw usb "no psu," back 2 pins for normal function.
Cant see that being the problem. Put your cache to 63 under, printer settings, communication and that drop down menu for restart on emergency button.
On your baudrate page under the baudrate.
Try that but im having issues with this board too its the melzi, your motors look off too like mine.
Could be firmware im new too but ive been researching hard hard aha.
