Hello reprappers!
I just finished building my Mendel Prusa and I'm having trouble getting it connected to my Windows 7 computer. I think I've successfully installed the Arduino drivers with the Sanguino additions, but when I fire up the RepRap host software and try to move the motors, nothing happens (and it reports a 0.0-degree bed temp). I can't figure out how to troubleshoot from here. The electronics are Sanguino 1.3a with the Sprinter firmware loaded, but I can't even figure out if communication was working. I didn't want to run the Arduino blink example as I assume that would overwrite the firmware that's there. I did calibrate my stepper-motor drivers according to the instructions, though I erred a little on the low side, as I had two multimeters that disagreed at that low voltage level (they agreed on the 12v source). Any suggestions would be greatly appreciated.
Thanks.
Andrew
