    the pitch roll position didn't look like in the excel, but like sway or surge

    I dont know, thats a new one... you should take some videos of it,.. show any code that you have modified... I will see if I can help.

    It's so cool!
    I also want to build something like this
    Already started to take the first steps :)

    Thank you very much for the information!

    This servo could likely be used with some tinkering - the PCB connector to the driver box may need to have some modifications... but the low level of this logic is incrementing position step, and direction, and looking at the pinout it does support step and direction signals.. voltage requirements on the signals, and other specific engineering issues may arise after this,.. but from a high level this should be a good start...

    I can provide the PCB source files (for online editing on easyeda.com) if anyone would like to tinker with changes.

    Hi , thanks a lot for your fast info .
    I can see you have only one output ( direction and step ) HV1 and HV7 for Motor 1.
    For step
    For the low level of this logic is incrementing position step, 3.3 volt PWM to 10 volt analogic , I can use this ?:

    My first simulator with Esp32 work with this analog ampli and work realy good !
    But can I use only one input step+ ( Drive I/O Connector number 10 ) ?

    And for direction : I can use optocoupler 5 vdc to control another 10vdc to 24 volt relay at the Drive I/O Connector 12 and 13 .

    maybe i'm completely out :rolleyes: ....

    to move to controlling PWM that would be a large change in design, without significant testing its hard to say what impacts this would cause placing those other parts in the circuit,... if i was you, I would try to interface one motor using an arduino and whatever other parts are required to move it..... get it moving reliably in one direction first,..then get the direction change working,..the circuit/code is very optimized in its current form,.. so adding other bits into it may slow it down,.. so there is a risk there. though if you can interface it there is a good chance you can get it working.... are you sure the position step is only PWM?... sometimes these motors have several different ways to drive it...

    Thanks for sharing everything from your project! I am super impressed with your compact design and I'm actually in the midst of my own project to make a compact 6dof as well.
