    I agree, I should have. But the simpit is shut down for the evening. As mentioned, the SMC3 settings are stock but I will get some screenies up tomorrow if I cannot figure it out. :)

    I knew there was some slop as the issue is with the gear connected (welded) to the output shaft. It seems to be slightly small and doesn't mesh well with the three internal gears. I need to take it apart and see if there is a way to adjust the three internal gears closer to the center. I doubt it but it is worth a try.

    @Historiker turn your clipping off maybe or max it out ?? then the motor wont be turning itself off because its going beyond the limit in SMC3 shutting it down ?

    I had thought of that as well, but no I have it out to the max setting . As a matter of fact my motors do not have enough travel anyway. I need to regear my pots to get more range.

    I removed the electronics to put them on the bench and inspect the connections. I did not find anything amiss so will get them plugged back in and some screenshots/pictures later today. Here is a picture of the
    Arduino/Pololu setup.

    WARNING: @Pit , @SeatTime , cover these pictures with your hand when you read this so the tangled mess of spaghetti will not upset you! :D

    Someday I will reconfigure my wiring but for now I just spliced into the setup that I had been using for the old motors. I added another Pololu 755 to each motor one at a time so I would not get the wiring...er..messed up....any more than I already had it :)

    Bench tested fine, and everything seems to work as far as power output and Simtools. Just have the eventual motor 1 drop after 10-20 minutes of gaming requiring an Arduino reset.

    Possibly swap the Pololu cards around and see if one is faulty or maybe is it a heat issue ? Is it just turning itself off with load on it or is it turning off when you are just on the test bench ?

    No issues at all on the test bench but then I am not putting high amperage through them then either :)

    Good idea about swapping drivers around. I will have to remove them from this arrangement and use breadboards as @Pit recommended in his MM thread.

    Yeah im just thinking of a process of ilimination until you find the fault, could possibly be overheating issue those heatsinks do look tiny. I take it you have fans when they are on the rig ?

    I do, but they do not get more than warm. This was true when I was using them as singles as well. As a matter of fact I was not using heat sinks at all with the old motors.

    Wow my MM's get scorching hot without heatsinks and fans and even with them on they get hot. If its not a heat issue thats one less thing to worry about :)

    Your opinion need not be humble Speedy, it always has gravitas :)

    But I have to admit that I do not exactly understand. I am using hall effect continuous turn pots, tested to make sure they are responding correctly in SMC3 before connecting power to the motors. The pots are clearly marked with the polarity and sweeper (not the correct term for hall effect I know) and they are connected so on the arduino. And of course the polarity on the motors seem correct as the motors seek pot center when powered on. The rig does work well for 10-20 minutes. I would assume that if the pots were not wired correctly I would not get the proper movement from the sim?

    But (part 2) I will definitely test my connections to verify that the two connectors are not swapped internally.

    Thanks for the tip.

    IMO if the rig works fine for 20 minutes I assume an overheating issue.

    Exactly ... OK pots are fine then

    So, (2nd opinion) review the max outputs in the game engine ... it may be forcing the Arduino to hit the max. limits so it is shutdown ...


    Edit : @Pit ... I guess it is not a heating problem cause @Historiker is resetting the Arduino and it is alive again ...

    Nice buzzle BTW ... :) more description please .

    I was thinking that an overheated driver might be causing a feedback issue for the arduino?

    Nob ... there is no actual relation between them ... when the driver is overheated resetting the Arduino will not solve the heat problem issue ..

    @Historiker please can you check out after the motor driver was shutting down and directly after that you start SMC3 the driver will be alive again?
