I think I've got a broken UM board:
Recently bought UM kit, with UltiController - spent the weekend building it meticulously and was mostly successful. I got the system powered up, saw output on the UC, was able to see menus (got the motors to go to home position at front left) etc.
Then moved on to connecting with computer, using Cura 13.04-2 (Linux Fedora 18 x86_64), added myself to the dialout group to be able to get comms permission, ran Cura, cancelled first time wizard, switched to 115200 baud. All OK so far. Then ran first time wizard again - uploaded the latest Marlin firmware and then problems ever since:
Whilst firmware can upload and I can see comms back and forth with Arduino there's nothing from the printer itself apart from the buzz of the fan and the motors getting rather warm.
The display on the UC now just shows a row of white blocks row of blue, row of white and another row of blue. I've adjusted contrast as discussed on the forum to no avail (even tried switching the cables over - no change).
I've re-flashed the firmware several times (uploads and verifies) and get nothing different - I'm now suspecting it's the UM main board but I'm not sure how to diagnose / confirm this - any pointers?
I'd love to get up and running and do my first print but think I've hit an insurmountable brick wall and will have to get the UM board replaced before I can proceed. :(
