    Hey guys,

    i am messing around with my first setup, 2DOF, IBT2 H-bridge. And I wanted to use one of my old arduino mega 2560s for this project.
    The smc3 firmware flashes just fine, but i cant get it to run on more than one direction, strangely pwm 11 is the only one active pwm pin for motor 1, while A0 is motor1 feedback as expected.
    Yes it is a clone sadly, but it worked perfectly when i used it for my 3d printer back in the days, so it should be running this code easily..
    would you have some recommendation for me please?
    i also have another uno r3 clone, wich gets flashed with smc3 but is not recognized by smc3 utils 1.01.

    i did order an original uno r3 now, but this takes some days and of course i wont give up wasting my time with these clones..

    Any idea would be appreciated :)
    Thank you!

    Many members have reported that clones and other Arduino models do not always play nice with SMC3, hence consider putting aside your existing hardware for other potential purposes and projects, as waiting on an original Uno is likely to save a lot of wasted time and angst, which you have already encountered.

    All right, today i tried SMC3 with my arduino nano clones - and they seem to work just perfect, i could finish my electrical installation now with SMC running really smoothly my 2DOF setup.

    Do you have any concerns about that atmega 328p chipset in general or the device itself?
