    Can anyone help me with the simtools settings? I'm trying to do a test inspired by a post seen here that uses 2 rc servos, for now they work but I don't understand what to put in axis assignment and what to write in the 3 interface setting items, can someone explain to me in order to understand the meaning of what I write thank you.

    Download a copy of the SimTools manual and keep it handy for reference: https://www.xsimulator.net/community/faq/rtfm-start-with-the-official-simtools-documentation.117/

    Your interface settings suggest you are using @eaorobbie's RC code.

    Your Axis Assignment are for 2 axis, but Axis1a should be Roll for both DOF1 and DOF2, with the Dir box being checked orange or not determining which way each axis moves. This is what SimTools expects: https://www.xsimulator.net/community/faq/which-way-to-set-simtool-axis-movements.230/

    Same for Axis2a, DOF1 and 2 should be set to heave.
    You can assign more axis, even on a 2DOF, and those normally include pitch, sway and surge, in addition to the two you already have.

    There are a bunch of configuration tips in the FAQs: https://www.xsimulator.net/community/faq/simtools-settings-tips-and-tricks.18/category

    Like total axis allocation being kept to around 100% total, to avoid clipping: https://www.xsimulator.net/community/faq/axis-assignment-percentage-totals.120/

    And tips for refining a motion profile: https://www.xsimulator.net/community/faq/steps-to-create-a-motion-profile.228/

    thanks, I'll try to read the simtool manual well, I'm working hard to learn, I'm also trying to read a lot of things written by users but I realize that many things they take for granted but I don't understand them. even the entries that say: R<Axis1a>~L<Axis2a>~ I don't understand in which sense they should be applied, for a 2 dof this is fine or you can also put it like this: R<Axis1a>~R<Axis1b>~ L< Axis2a>~L<Axis2b>~? If you can explain the meaning to me I would be grateful.

    For a 2DOF R<Axis1a>~L<Axis2a>~ is the correct Interface Output settings, it defines how the Right and Left axis are designated.

    It is very hard to determine or give advice regarding changes when you have not concurrently posted pictures of all of your settings, that contribute to what is observed in the video.

    It is clear from the video that some axis configurations that contribute to the experienced effect of motion, such as sway, are not properly configured.

    I did it, now it looks good, thanks @noorbeast for your help!
    I was thinking of creating a new post where I explain the whole procedure even if perhaps there are already others but I wanted to make it more complete, proof of the clumsy like me who describes the whole procedure step by step, what do you think?then I also wanted to insert the stl files for printing so if one wants to do the same and doesn't want to draw them, download them and print them..

    Great to hear you got it working :thumbs

    I would likely be best to continue this thread with explanation and STL files, as it provides context and continuity.

    ok so tomorrow I'll put the print files here then I take a good look at the photo of the axis parameters that maybe I made a mistake in putting the right one, maybe I'll make a quick summary of everything! anyway I wanted to make this project to get some experience but if one wanted to create it real would it be suitable or would such large servos cost too much?

    here for those interested I attach the files for 3d printing

    and this is the wiring diagram, for the codes, search the forum for the rc model code that a user did, all this work I did apart from 3D printing was all inspired by this forum.
    however, for those interested, I am available to answer your questions.
