    Replaced the MM, replaced the ArdUNO - it died too - both with the Chinese clones.
    It all worked for a couple of hours then the new Arduino died with no reason (no TX signal, PC doesn't see it anymore).

    At the moment I'm very discouraged, I should order another one, but there is the chance I could brake the new one too not knowing what broke it :(
    Maybe I'm leaving the project, maybe I'll go for JRKS, right now I don't know


    Anyway, attached you can find a driver I found for the Arduino Uno Chinese clone I found, that they delivered with no driver. It's for the CH341 chip.

    That is very disappointing for you @Blame73.

    That something works then dies after a couple of hours is very odd. Just a stray thought but it sort of sounds like something moves and then shorts.

    @Blame73: please de-wire the Ard from the MM. To check the arduino, first connect it via USB to the PC, push the reset button.
    Measure the pins "5V" and "3V3". If that is OK, re upload the Ard code of SMC3. Connect one pot as described in the SMC3 tutorial to control one motor. Start SMC utility, have a look of the Ard leds, they should flicker while starting SMC3. Check the values within SMC3. Perhaps you got a fake board. You never know...

    Thanks for the answer @Pit , I could measure the pins but I can no way re upload any codes since PC doesn't see arduinos anymore, no more COMs, as if the USB chips on the ard were dead.

    Nope, reset didn't solve it.

    The difference between the two boards is that the clone one has the RX led lit.

    mate, a clone of what? IMHO you bought the "wrong" hardware components, the quality of the manufacturing process is behind good and evil...sorry I have to say that.

    PS: I remember you are living in Italy. The original UNO r3 costs ~€20.-.

    I own both, I'm from Italy and I bought the original Arduino Uno for the full price.
    I also bought the Chinese one with two MMs from China as a backup.
    the original died, the 'clone' died after two hours of regular use. I'm aware it's a lot different technically speaking, I was just pointing out that the clone still had the RX led lit while the original doesn't, but both aren't seen by the PC

    hmm, sorry for misunderstanding. If the original died under normal working conditions,you could send it back for an exchange under warranty?

    PS: if both died you should have a deeper look in the wiring, creeping current, current leak, return current...
    My arduinos and MMs are running now more than 6 months w/o any issues.

    PPS: Perhaps you have to use an USB Galvanic Digital Isolator.

    Sorry its gonna sound like im a jerk, But damn i love my JRK's.



    Again Sorry to hear your woes Blame, I vote JRK if you couldn't guess already. ;);)

    I can't send it back, the first one probably died when I killed the MM by stupidly switching the power wires :oops:
    The second one, I have to investigate otherwise I could kill everything I'd use

    That's what I'm gonna probably do: two JRKS for 2DOF and since I still have MMs, order a couple of Chinese UNOs ad use 'em for traction loss.
    Well, I'm assuming I could run both (JRKs and Ard) together...

    Just ordered two JRKs 12v12

    @bsft did you write any guides to configure the software? I remember I saw something among the thousand pages I red this last month on the forum

    I have a arduino clone infact I have 2 and have no issues what so ever they work great even after doing the exact same thing as you did with your MM.

    I would try reburning the UNO bootloader back on using your spare UNO see if it works.

    full details there , it may not help at all but worth a try :)

    Thanks @SilentChill .
    One question, since English is not my first language (...): it says I have to "add a 10 uF capacitor between reset and ground"
    Having I two Arduino Uno, do I have to add it to the programmer, to the target, between target and programmer or on both?

    Edit: it's not that it matters, since I can't upload any sketches... PC can't see both boards, so can't connect to them
