Hi all,
I've got a Prusa i3 with a RAMPS 1.4 setup - a kit from reprapdiscount with the smart display.
Yesterday I went to use the printer, and did the usual stuff - turned on the ATX power supply, then plugged it into my laptop's USB port. However the laptop immediately rebooted, and the RAMPS reset itself (the smart display reset so I'm assuming the entire ramps board reset at the same time).
I then tried plugging into the USB port without the ATX power supply turned on, and whilst it powered the MEGA and RAMPS via USB, I cant connect via pronterface anymore. I've tried different USB cables, different ports, etc however it's simply not picking up that there is even a USB device attached.
I was wondering if anyone else had experienced anything like this? The printer still works fine using an SD card for printing, but wont communicate over USB (despite being able to draw some power via USB ).
Have I blown the USB port on the MEGA? Would it be worth picking up another MEGA board and trying that out?
