  • Ah… so I have failed and now have a dead duemilanove and easy driver.
    as a general question, how do I know how to hook up a given 4 wire stepper motor to this board ?
    I can test the connection between wires, so that gives me the wires for each coil, [a] [b], but .. does the orientation matter ? This still leaves open 4 possible writings ( 2 directions x 2 coils ).
    Whatever I hooked up worked for the default largest step size, but made weird noises when I tried to turn on half stepping. I wondered if orientation mattered, and how to test for this ?

    - people reselling on e-bay are sociopaths.
    - free day would have been over in seconds if servers had been infinitely fast: expect to lose either way.
    - brilliant advertising
    - Will you guys make enough money in the next week to cover free day, by virtue of people who didn’t get the discount placing smaller orders ?
    - Sounds like you should see if you can fund a small sponsoring program for poor college students ( submit schematics, cartoons, get X dollars in Free ? )
    - got in at the end (10:44). I was watching the little progress bar advance the whole time wholly expecting disaster. I will now be able to make a prototype for a new do-it-yourself. I usually dumpster parts, and I am grateful for this (less bleeding and snow involved, (besides, where am I going to get a boost converter in the trash (though I did find a nice little MIDI board the other day))?).
    - Free day went exactly as expected and exactly as advertised. It is unfortunate that some people had higher expectations that were dashed.
