    Hello all awesome guys

    First of all special thx to this guy I call now Mr awesome. Its crazy what you have realised and even more that you are still giving support after all these years.

    I'm really looking forward to copy your hell machine and reading/gathering information about building 6dof Plattforms for nearly 6 months now. Since my budget is very limited I have to find a solution for these superexpensive AASD15A drivers as well as for the planetary gears.
    Before I throw my mind and life completely into this project I have to check first several points:

    1. Can i use an alternative driver?
    This is the description at amazon (sorry, I'm not allowed to post links yet.)
    Ac Servo DriveHTNC-C30S-L20A-RABN-B

    I've tried to understand your controller architecture (without reading the code). As much as I know thus driver is similar to the AASD15A. But I don't know if the commands for communication are the same. Do you think it is possible to adapt your controller and software to this driver? Or do you think that it will be like developing it from the roots?

    2. I don't think I,ll be able to manage this completely on my own (especially the coding part). Do think it will be possible to rely on your awesome support?
    I think this project would help a lot of people with budget issues.

    My background:
    I'm an aerospace engineer with the possibilities to construct most stuff on my own. Only my programming knowledge is limited. But with chatgpt I have realised my own hotas with arduino. I understand the fundamentals of programming but I don't know the syntax etc.

    So what do you think Mr awesome?

    I took a look at the website for the driver, they do say that it works with step/direction commands for control, as one of their methods, these drivers do look like they can be used with multiple communication protocols, step/direction being one of them. you may be on your own as far as wiring them as they may/most likely are not the same, but that should be a trivial task... give or take... what is step/dir control you may ask,... just pulses ,each step the motor travels, it gets a pulse for the given direction that is indicated by the dir wire, high or low, forward or back. will take some tinkering to get the ratios and virtual gearing right, but should be dooable.

    I can help, I dont spend much time on this lately, got other bigger projects i am working on. but i can help,, suggest attempting to play with 1 motor at first, once you get it working/ characterize its ability with the pcb circuit, then the rest of the build becomes trivial.
