Stigern, thanks. I mostly print using USB. I thought maybe my cable or the port was bad so I wrote the gcode to an SD card to try it. That way I'd eliminate the whole USB connection path. It failed the same way, so, I know my cable is probably OK.
I have everything taken apart. Today I'm going to totally rewire the whole machine. I'm going to also switch the stepper driver boards around and see if I can get a failure on a different axis. That might help me diagnose what component is bad. Finally, I have a new RAMPS coming via Amazon tomorrow. If my tasks today fail, I'll have a new board. If the new board fails, then I'll have a whole RAMPS board that I can then use to build a new printer one day. I wish I knew how to test stepper motors and have also been looking for info on testing/diagnosing the Mega 2560. So far I haven't found anything useful.
EDIT: I found a simple way to test stepper motors. Pretty handy: https://www.youtube.com/watch?v=27pplRj_384Last edited by RobH2; 11-28-2014 at 09:53 AM. Reason: stop, halt, stepper, test, led, mega, ramps,
